# Ars Magica *Created:* 2026-09-12, *Modified:* 2026-11-03 ![[Ars Magica - Revised Edition (cover).jpg]] ![[Ars Magica - 4th Edition (cover).jpg]] ![[Ars Magica - Definitive Edition (cover).jpg]] *Left to right: the Revised Edition (1989), Fourth Edition (1996), and the Definitive Edition (2026) — the illuminated 1996 cover is the one the Definitive Edition's gold on leather is quoting, two editions on.* **Ars Magica** is a game about wizards as professionals — members of a guild with a legal code, a House, a shared research tradition, and an overwhelming preference for being left alone with their books. It is set in 1220, where the folklore is true and the most powerful people in Europe are a small, suspicious order of scholars who have sworn not to rule anyone, largely because ruling people is how you start a war and the last one cost them one of their own Houses. Everything else in the game follows from that: if you are that powerful and that constrained, then ambition has to go somewhere, and in this game it goes into the laboratory. The **Definitive Edition** (2026) is that game in its final, enormous form — still Fifth Edition, but with two decades of errata and supplementary rules folded back in, twice the page count, new art, and a gold-stamped leatherette cover priced like an heirloom rather than a rulebook. ## Setting **Mythic Europe** is the Middle Ages with the myths left switched on: "a world very like the Middle Ages of our world, but with magic," set by default in 1220. That means history as written — popes, kings, crusades, guilds, bad roads, worse medicine — with everything medieval people believed sitting on top of it as literal fact. Angels guard shrines, demons stalk cities, faeries make mischief in villages, and dragons lair in the Alps. The Church holds the **Divine** realm and the **Dominion** aura that comes with it; the wilderness belongs to the **Magical** and **Faerie** realms; and something worse keeps its own. ### The Order of Hermes The game's spine is the **Order of Hermes**, founded in the eighth century when the wizard Bonisagus produced a universal theory of magic — one that could be taught, written down, and shared — and, with it, the **Parma Magica**, the ritual that lets magi stand near each other without instantly trying to kill one another. Trianoma handled the politics, and the result is a continent-spanning body of roughly 1,200 magi, divided into thirteen **Tribunals** and twelve **Houses**: Bonisagus, Bjornaer, Criamon, Ex Miscellanea, Flambeau, Guernicus, Jerbiton, Mercere, Merinita, Tremere, Tytalus, and Verditius. They are bound by the **Code of Hermes**, which forbids interfering with mundanes, slaying fellow magi, and a handful of other things magi would otherwise do constantly. Disputes go to **Tribunal**, which convenes every seven years; the **Quaesitores** of House Guernicus investigate breaches and present the evidence. The Order has already survived one catastrophe of its own making — the **Schism War** of the early eleventh century, which destroyed House Diedne and very nearly destroyed the Order with it. ### The Gift and the Covenant Magic comes from **The Gift**, and The Gift makes ordinary people uneasy in a way they can't articulate. That single fact explains the game's entire social architecture. A magus cannot run a shop, hold a bishop's trust, or pass for a normal person for long, no matter how charming. So magi build **covenants**: fortified houses on a magical aura, with a library, laboratories, servants, tenants, and a source of raw magic. Covenants are classified by season — Spring for the newly founded, Summer for the rising, Autumn for the established, Winter for the dying — and the covenant is treated as a character in its own right, with its own resources, flaws, and stories. ### The Four Realms Every supernatural thing belongs to one of four **Realms** — Divine, Infernal, Magical, Faerie — and each projects an **aura** that strengthens its own powers and penalizes everyone else's. A magus casting in a town with a Dominion aura of 3 is at −9 and rolling three extra botch dice, which is why magi prefer their own hills. Creatures of the Realms have a **Might** score, which is both their power ceiling and the fuel for their abilities. And not all magic is Hermetic: hedge wizards, cunning folk, and rival traditions exist outside the Order, usually to the Order's irritation. ### Magi, Companions, and Grogs Characters come in three tiers. **Magi** are the wizards, the most powerful characters in the game and the reason the saga exists. **Companions** are important non-magi — a knight, a friar, a noblewoman, an unGifted Redcap — who carry the stories magi are too busy or too alarming to carry. **Grogs** are minor characters: guards, specialists, servants, and the people who die so the magi don't have to. Play is **troupe-style**, meaning most players run a magus plus a companion or a stable of grogs and switch depending on whose story is being told. ## Mechanics ### Resolution Most actions are **Characteristic + Ability + die roll** against an **Ease Factor**: 6 is easy, 9 average, 12 hard, 15 very hard, 18 impressive, 21 remarkable, 24+ "the greatest masters of a skill succeed when they get lucky." There are two dice. The **simple die** is a d10 read straight, zeros as ten — used when nothing is at stake. The **stress die** is the same d10 read with two exceptions: a **1** means roll again and double the result (and keep doubling if you keep rolling ones, which is how totals in the hundreds happen once in a long saga), and a **0** means zero *and* a **botch check**. Roll the botch dice — one by default, more for bad conditions or hostile magic — and any zero among them is a botch, which reduces your total to zero and makes something go badly wrong. More zeros means worse. Characters also spend **Confidence** points for +3 each, decided after the roll is known. ### Character Creation You start by picking a tier — magus, companion, or grog — because the tiers buy different things. Characteristics are bought with **seven points** (scores run −3 to +3). **Virtues and Flaws** are bought on a **ten-point Virtue budget against up to ten points of Flaws**, at three points for Major and one for Minor; magi must take The Gift, and each House hands out a signature Virtue. Childhood gives **45 experience points** of Abilities, later life **15 per year**. Magi then get the part that makes them magi: **240 experience points** divided between Hermetic Arts and non-Supernatural Abilities, plus **120 levels of spells** in total, none of them above Technique + Form + Intelligence + Magic Theory +3. An optional rule adds **30 points per year** for time served after the gauntlet. Magi and companions start with a Confidence Score of 1 and three Confidence Points; grogs get neither. ### The Arts Hermetic magic runs on fifteen **Arts**: five **Techniques** — Creo (create), Intellego (perceive), Muto (transform), Perdo (destroy), Rego (control) — and ten **Forms** — Animal, Aquam, Auram, Corpus, Herbam, Ignem, Imaginem, Mentem, Terram, and Vim. Combine one of each and the Latin tells you what the spell does: *Creo Ignem* makes fire, *Rego Corpus* makes a body do what you want. Your score in a Form also gives a small bonus (a fifth of the score, rounded up) to resist damage of that type, so a magus with a high Ignem is harder to burn. ### Casting Your **Casting Score** is Technique + Form + Stamina − Encumbrance + the local aura modifier. What you do with it depends on which of three kinds of magic you're using: - **Formulaic** — a spell you actually know. Roll a die, add your Casting Score, compare to the spell's level. Meet it and it works cleanly; miss by up to 10 and it still works but costs a Fatigue level; miss by more and it fails and costs a Fatigue level anyway. Most magi live here. - **Spontaneous** — magic invented on the spot. Divide (Casting Score + stress die) by 2 for a fatiguing version, or your Casting Score by 5 for a free one. Weaker, endlessly flexible, and the reason magi can always do *something*. - **Ritual** — the big, permanent work: fifteen minutes and a pawn of vis per magnitude, always on a stress die, and a long-term Fatigue level even when it works. Spell levels are built rather than looked up: a base effect plus **magnitudes** for Range, Duration, and Target, at five levels per magnitude. That's why "I make a light" and "I make a light that follows the duke for a year" are the same spell family and not remotely the same spell. ### Penetration and Magic Resistance Hitting a supernatural target is a second contest. **Magic Resistance** for a Hermetic magus is Form + (Parma Magica × 5) + aura; **Penetration** is your Casting Total plus your Penetration bonus, minus the spell's level, plus aura. If Penetration doesn't exceed Resistance, the spell simply doesn't touch them. **Arcane connections** — a birth name, a horoscope, blood, a signature — multiply your Penetration ability, which is why magi are so careful about what they let people keep, and why a pawn of vis spent at the right moment can push a spell over the line. ### The Laboratory The other half of the game happens indoors, one season at a time. Your **Lab Total** is Technique + Form + Intelligence + Magic Theory + aura, and a season of laboratory work buys one of: inventing a spell, enchanting an item, fixing an arcane connection, extracting vis (a tenth of your Creo Vim Lab Total in pawns), binding a familiar, brewing a Longevity Ritual, or training an apprentice. Laboratories themselves are customizable, with their own Virtues and Flaws, and **experimentation** is a real gamble: push the Lab Total too far and the Extraordinary Results chart may hand you a discovery — or a side effect, a wrecked lab, an explosion, and two Heavy Wounds. ### Warping and Twilight Living near magic changes you. **Warping Points** come from strong auras, powerful effects aimed at you, continuous enchantments, and botched supernatural rolls; the **Warping Score** rises like an Ability, at five times the new score in points. Gain two or more points from a single event and a magus must roll to avoid **Wizard's Twilight** — Stamina + Concentration + Vim + stress die against Warping Score + the points gained + Enigmatic Wisdom + the local aura, with the Twilight rolling a stress die of its own. Fail, and the magus goes somewhere else for a while; how long depends on the Warping Score — two minutes at 1, seven years at 8 — cut short by however well he comprehends it. At 10 or higher, the Twilight is **Final** — the magus becomes a creature of pure magic and stops being a player character. It is the game's quiet answer to immortality, and it is not a kind one. ### Combat Combat is not the point of **Ars Magica**, but it is genuinely dangerous when it happens. Five totals: Initiative (Quickness + weapon − Encumbrance), Attack (Dexterity + Combat Ability + weapon), Defense (Quickness + Combat Ability + weapon), Damage (Strength + weapon + Attack Advantage), and Soak (Stamina + armor, plus Form bonus for magi). **Attack Advantage** — your Attack Total minus their Defense Total — feeds straight into Damage, and the wound table reads by Size: a Size 0 character takes a Light Wound at 1–5, Medium at 6–10, Heavy at 11–15, Incapacitating at 16–20, and dies at 21+. Botch a Defense roll against a competent opponent and the math does what the math does. ### Seasons and Advancement Time is the real currency. Advancement is measured in **seasons**, not sessions: a season of study, teaching, practice, or adventure produces experience points, and **Source Quality** sets how many. Books are the fastest route to power — *summae* that teach a subject to a level and *tractatus* that can each be read once — and the Order maintains standard primers called the Roots and Branches of the Arts. Arts cost (current score + 1) experience points to raise; Abilities cost five times the new score. Characters also age, roll on the Aging table, accumulate Aging Points and Decrepitude, and eventually turn to a **Longevity Ritual** — which buys decades at the price of a Warping Point a year, forever. ## Editions - **Ars Magica** (1987) — Lion Rampant's 160-page first edition, by Jonathan Tweet and Mark Rein-Hagen: the Form-and-Technique magic, troupe play, and Mythic Europe all present from the start. It took the 1988 Origins Gamer's Choice Award. - **Ars Magica Revised Edition** (1989) — Lion Rampant again, and the first edition to reach wide circulation: a streamlined rulebook, and the one that put seasons at the centre of laboratory work and advancement — and still this garden's pick of the lot. - **Ars Magica Third Edition** (1992) — White Wolf's revision, co-authored by Rein-Hagen with Ken Cliffe: darker in tone, 392 pages of much expanded setting and peripheral rules, and the first appearance of Passions. - **Ars Magica Fourth Edition** (1996) — Atlas Games, landing after the rights moved from Wizards of the Coast: Jeff Tidball developed and edited it with John Nephew, on Tweet and Rein-Hagen's original design, and it was an Origins Award nominee for Best Roleplaying Rules. *In the library.* - **Ars Magica Fifth Edition** (2004) — Atlas Games, with David Chart as line developer; the longest-lived edition, and the winner of the 2005 Origins Award for Best Role-Playing Game and an ENnie gold for Best Rules, with a silver for production values. Chart's **four design notes** for the revision (now in the library) are blunter about the scale of the change than any blurb: Fourth Edition combat was "broken" — the more armour you wore the more damage you took, so "the mightiest force on the medieval battlefield was a naked man with a stick" — and he threw the whole thing out and rebuilt it on the same five statistics. The Laboratory was unified so every activity runs off one **Lab Total** with no exceptions, and the spell guidelines were re-based so that every Technique and Form pair shares a common Range, Duration and Target, which ended both the "level shaving" exploit and the old exception-making around wards and magical senses. Story and Personality Flaws were reworked as well, from disadvantages into hooks the storyguide can actually rely on. - **Ars Magica Definitive Edition** (2026, copyright 2025) — Atlas Games; crowdfunded on BackerKit in the autumn of 2024 and printed at 582 pages, over twice the size of the Fifth Edition rulebook. Still Fifth Edition rather than a sixth: David Chart's brief was to gather rules that had been scattered across more than forty supplements — Mystery Initiation and the integration of non-Hermetic magic among them — plus years of errata, clarifications, and a slew of small integrations, with all existing supplements remaining compatible. The set ships with a storyguide screen, a 14-page Reference Guide booklet, printable character sheets, and a poster map of Mythic Europe, and the core text is released under a Creative Commons BY-SA 4.0 open license. *In the library.* ## Supplements The Fifth Edition line ran from 2004 to 2016 and past forty books, and the **Definitive Edition** absorbed the pieces of it that belonged in a core rulebook. What remains is regional, institutional, and practical — how the Order actually lives rather than how it casts. ### The Houses of Hermes - **Houses of Hermes: True Lineages** (2005) — Bonisagus, Guernicus, Mercere and Tremere: the four Houses where every magus was taught by a magus of the House, master to apprentice back to the founders. Adds **original research** and each House's own forms of magic. - **Houses of Hermes: Mystery Cults** (2006) — Bjornaer, Criamon, Merinita and Verditius: the Houses whose magic is a set of Mysteries, initiated one at a time under a House Lore, from the Bjornaer Heartbeast to Verditius crafting. - **The Mysteries (Revised)** (2006) — the Mystery Cults beyond the Houses, and the machinery for joining them: initiation scripts, Hermetic alchemy, Hermetic astrology, and sample cults with their own secrets. - **Houses of Hermes: Societates** (2007) — Flambeau, Jerbiton, Tytalus and Ex Miscellanea. Flambeau "celebrates fighting for a cause"; Jerbiton seeks beauty in life; Tytalus "thrives on combat: between nature and law in the soul of the magus, and with the world around him." - **Legends of Hermes** (2011) — five of the Order's great magi written up in full, on the argument that they may be the most detailed characters the line ever published. - **Apprentices** (2012) — the fifteen years before the gauntlet, from a page and a half in the core to a book: stories about children, rules for creating young characters, and what a master actually teaches, cantations included. - **Grogs** (2012) — the minor characters promoted to protagonists: grog concepts, the life of a grog, and the bookkeeping that makes a turb playable, with rules for running years of aging at once and training packages to update them between sagas. ### The Realms of Power - **Realms of Power: The Divine** (2005, revised 2011) — the highest and most sublime powers: the three faiths of Christianity, Islam and Judaism, the ubiquitous Dominion, miracles, and the Heavenly Host. The revised edition replaced the original's Judaism chapter after plagiarism was found in 2009 — text that had already appeared in the Fourth Edition's *Kabbalah: Mythic Judaism* — and the new chapter was posted free. - **Realms of Power: The Infernal** (2006) — the legions of hell: sample demons by the dozen, rules for corrupting auras and Infernal vis, characters tainted at birth, and the traditions of the infernalists. - **Realms of Power: Magic** (2008) — the realm the book calls "at once the most familiar and the most alien": the source of Hermetic power and entirely indifferent to human concerns. Auras, the realm itself, and its characters, from elementals to dragons to spirits bound to the natural world. - **Realms of Power: Faerie** (2009) — the good neighbours, who must not be named: Faerie auras, more than one Faerie realm, the fae themselves, humans they have touched, and **ars fabulosa**, the bargains by which a wizard buys faerie power. ### Magic Beyond the Order - **Ancient Magic** (2007) — Hyperboreans whose spells lasted a generation, Canaanite necromancers, rune magic that "brushed aside Magic Resistance like cobwebs": magics old enough that only legends of them survive, written for Seekers to find and possibly integrate into Hermetic theory. - **Hedge Magic Revised Edition** (2008) — six hedge traditions to play, or to use as allies and antagonists: the scholarly **Mathematici** clustering in universities, village folk witches, elementalists, the curse-and-blessing **gruagachan**, the nightwalkers, and the Norse **vitkir**, whose chapter carries the Order of Odin and the rune poems. - **Mythic Locations** (2014) — the great supernatural places of Mythic Europe, where the four realms have left their marks on the landscape: Bath, Bear Island, the Farne Islands, the Cursed Waste and more. The book was kept deliberately spoiler-light, with no public table of contents. ### The World - **Covenants** (2006) — the covenant built as a character: Major and Minor **Boons and Hooks** across sites, fortifications, resources, residents, external relations and surroundings, with structure flaws to pay for it — then actually run, through chapters on governance, covenfolk, wealth and poverty, vis sources, the **library**, the sanctum, and the **laboratory**. - **City & Guild** (2006) — the urban Mythic Europe: towns, labour, guilds, crafts, travel, fairs and markets, with commerce rules built for stories rather than ledgers. - **Art & Academe** (2008) — the other scholars of Europe: Artes Liberales, Philosophiae, medicine, experimental philosophy, and the universities of 1220, with rules for *disputatio*. Timothy Ferguson, who writes for the line, calls it "the big book of 'Timothy, you can't do that'" — a complaint about canon limits from somebody who has to write around them. - **Lords of Men** (2010) — the nobility who rule Mythic Europe: the vows, land, and mutual obligation that bind them, plus a chapter on the peasants who support them, and mass combat that resolves a battle as scenes rather than a miniatures game. - **The Church** (2011) — the institution that "touches every aspect of life, and every individual heart," worked outward from the parish: the congregation, the diocese, the religious life, the women of the Church, and the corrupt. Even magi in their covenants must contend with it — and many trust it with the salvation of their souls. - **Transforming Mythic Europe** (2013) — what magic would actually do to the world: land conjured from ocean, labour replaced, and a social order quietly upended by magi who never intended to touch politics. - **Hooks** (2014) — eight short scenarios, each tied to a published sourcebook, meant to be dropped into an existing saga rather than run as a campaign. - **Lands of the Nile** (2015) — Egypt under a sultan in Cairo, its ancient treasures dug out of the ground by the **Guild of Seekers** with his blessing; Christian Nubia, kept off the Muslim armies by an ancient treaty; and a resurgent Ethiopia whose ruler has just come back from Jerusalem. - **Dies Irae** (2016) — *A Book of Wrathful Days*, and the last book published for the line: wizards who serve the powers that ruled before the world began and plot to hand it back to them, wizards who would take everyone into a glorious new existence whether they want to go or not, and wizards with nothing but the best of intentions. ### The Tribunals - **Guardians of the Forests: The Rhine Tribunal** (2005) — the edition's first tribunal book, set in the land it calls the birthplace of the Order of Hermes: Mythic Germany, where prince-bishops, dukes and merchant gilds fight over temporal power and the forests are thick with faerie. It adds **The Gilds of the Rhine Tribunal** and the **Paths Through the Forest**, which the book suggests may explain the long-running disappearances of Rhine magi. - **The Lion and the Lily: The Normandy Tribunal** (2005) — the tribunal where the wilderness has been tamed and ploughed under, the Church plants monasteries in the wastes, and magi cannot avoid the mundanes: a vis-poor, deeply feudal corner of the Order that forces more interaction than most. - **The Sundered Eagle: The Theban Tribunal** (2010) — Byzantium after the Fourth Crusade: Constantinople sacked, and the ancient bindings once held by Rome's relics broken with it, releasing beasts and demons across the land. The monsters draw hunters and Seekers alike, and the book writes the Greek and Orthodox half of the Order as a place to go looking for them. - **Against the Dark: The Transylvanian Tribunal** (2013) — the land between two empires: Hungary under the richest king in Mythic Europe, with restless nobles and Teutonic Knights who want no overlord, dragons in the mountains and vampires in the villages, and "to the east, a greater storm gathers." It is also the home ground of House Tremere, whose domus magna at Coeris sits in the middle of it. - **The Contested Isle: The Hibernian Tribunal** (2015) — Hibernia, where the magi respect the land and its supernatural inhabitants, leave much of the tribunal to hedge traditions, and let supernatural creatures vote at Tribunal — until magi from elsewhere arrive to "reform" the Peripheral Code and lay siege to all of it. ### Earlier-Edition Tribunals Four tribunal books from before Fifth Edition, each still usable for the geography and the Order's history: - **Tribunals of Hermes: Rome** (1993, Third Edition) — the Roman Tribunal as the most magnificent land in Mythic Europe "and utterly damned": the powers of Darkness corrupt its people, taint its Church, and stifle its magic. - **Lion of the North: The Loch Leglean Tribunal** (1994, Third Edition) — Mythic Scotland: covenants inside faerie mounds with sentient walls, Saxon renegades in caves, the rough wizards called **gruagachan**, and old Damhan-allaidh at the end of it. - **Heirs to Merlin: The Stonehenge Tribunal** (1999, Fourth Edition) — England and Wales, by David Chart, from Arthur and the death of Thomas Becket to the coming of the Order and the rise of Blackthorn. - **Sanctuary of Ice: The Greater Alps Tribunal** (2003, Fourth Edition) — the tribunal that has kept the Hermetic peace for centuries, where Alpine covenants flourish undisturbed by the squabbles of the borders. ### Fan and Open-License Work - **[[Mythic Venice]]** (2024) — Timothy Ferguson's fan-created city sourcebook, released under the Ars Magica Open License and funded through his *Games From Folktales* Patreon (Atlas handed it to Definitive Edition backers as a stretch goal, but it isn't an Atlas book): Venice as a faerie theatre whose growing aura quarantines the city's anachronisms, with its factions by realm, a year of festivals, and a chapter of Venetian domestic alchemy. *In the library.* - **Ars Magica 5: Character Creation Summary** (2026) — Gary Barber's sixteen-page rules summary and flow diagrams for character creation. *In the library.* - **Forgotten Magic of Hermes** (2026) — Patrick M. Murphy's *A Mad Irishman Production*, v1.0: fifty-nine pages collecting spells from earlier-edition Ars Magica books and restating them in Definitive Edition terms under the open license. *In the library.* ### Freebies and Web Supplements Atlas has given away a long tail of small material over the years, and most of it is worth having at the table rather than on a shelf: - **[Promises, Promises](https://www.atlas-games.com/pdf_storage/promises.pdf)** — the Fourth Edition Jump Start Kit: a sixteen-page welcome to Mythic Europe that teaches the core rules through a starter story. *In the library.* - **[Nigrasaxa](https://www.atlas-games.com/pdf_storage/nigrasaxa.pdf)** — a three-part intro mini-saga for Fourth Edition, written to run after the Jump Start Kit, taking a new troupe through an extended tutorial saga. *In the library.* - **[The Icelandic Wars](https://www.atlas-games.com/pdf_storage/IcelandicWars.pdf)** — a Fourth Edition web supplement complementing *Land of Fire and Ice*: the conflict between Iceland and the Order, and the galdramen the magi would face there. *In the library.* - **[Secrets in Sand](https://www.atlas-games.com/pdf_storage/secretsinsand.pdf)** — a Fourth Edition web supplement that calls itself a supplement to a supplement: the material that didn't fit into *Blood and Sand*, including the Islamic Tradition. *In the library.* - **[Lords of Men: Arms and Armor](https://www.atlas-games.com/pdf_storage/LoMWebSupplement.pdf)** — an eight-page Fifth Edition web supplement to *Lords of Men*: the weapon tables, encumbrance, and weapon-breakage rules that overflowed the book. *In the library.* - **[Semita Errabunda](https://atlas-games.com/livingcovenant)** — a Fifth Edition "living covenant", packaged with twenty-three character sheets across magi, companions, and grogs. *In the library.* - **[Twilight's Inheritance](https://atlas-games.com/atlas-cms/resources/downloads/armtwilightsinheritance.zip)** — a Fifth Edition demo adventure, distributed as RTF with handouts, character cards, PC sheets, and maps. *In the library.* **Ars Magica**'s Form-and-Technique magic is also the acknowledged ancestor of the flexible casting in **[[Ironsworn - Arcanum|Ironsworn: Arcanum]]**, the fan-made high-magic supplement for **[[Ironsworn]]** — so if you want this magic without the six-hundred-page tome, that's the modern, solo-friendly way to get it. ## Related products - **[[Grand Tribunal]]** (2006) — the board game, and the only one Atlas has made from the line: three to five players spend Vis on item and spell cards, vote each round on which categories will be rewarded, and chase archmage status across three Tribunals. Phillip R. Chase design; no knowledge of the RPG required to play. *In the library.* ## References - [Ars Magica Definitive Edition - Atlas Games](https://atlas-games.com/definitive) - [Ars Magica Definitive Edition Set (AG0215) - Atlas Games](https://atlas-games.com/product_tables/AG0215) - [Ars Magica Definitive Edition - DriveThruRPG](https://www.drivethrurpg.com/en/product/584214/ars-magica-definitive-edition) - [Ars Magica Fifth Edition [digital] - DriveThruRPG](https://www.drivethrurpg.com/en/product/329468/ars-magica-fifth-edition-digital) - [Ars Magica Fourth Edition, free PDF - Warehouse 23](https://warehouse23.com/products/ars-magica-4th-edition-core-rulebook) - [Ars Magica Fourth Edition - Project: Redcap](https://www.redcap.org/page/Ars_Magica_Fourth_Edition) - [Ars Magica Open License - Atlas Games](https://www.atlas-games.com/arsmagica/openars) - [Ars Magica Open License corpus in Markdown - GitHub](https://github.com/OriginalMadman/Ars-Magica-Open-License) - [Ars Magica Definitive Edition - BackerKit campaign](https://www.backerkit.com/c/projects/atlas-games/ars-magica-5th-edition-definitive) - [History of Ars Magica - Project: Redcap](https://www.redcap.org/page/History_of_Ars_Magica) - [Game Mechanics - Project: Redcap](https://www.redcap.org/page/Game_Mechanics) - [Ars Magica - Wikipedia](https://en.wikipedia.org/wiki/Ars_Magica) - [Review of Ars Magica Fifth Edition - RPGnet](https://www.rpg.net/reviews/archive/15/15020.phtml) - [David Chart on Ars Magica Definitive Edition - Thoughtful Dane](https://thoughtfuldane.com/2024/10/10/david-chart-on-ars-magica-definitive-edition) - [Ars Magica: the Definitive Edition - Doctor Comics](https://doctorcomics.substack.com/p/ars-magica-the-definitive-edition) - [Ars Magica: Preserving 30+ Years of Wizardry - Thaumavoria](https://thaumavore.substack.com/p/ars-magica-preserving-30-years-of) > [!note] Editor's Note > > Definitely one of the best and most involved magic systems ever properly put to page.
