| Core Mechanic | Roll a d10 + Characteristic + Ability against an Ease Factor. Simple die rolls count the result at face value; stress die rolls on a 1 double the next roll (cascading), while a 0 risks a botch by rolling additional botch dice. Magic uses Technique + Form (five verbs like Creo, Perdo combined with ten nouns like Ignem, Corpus) to define any spell effect. Formulaic spells are pre-learned, spontaneous spells can attempt any Technique + Form combination by halving the casting total, and ritual spells handle large-scale or permanent effects. | Roll d20 + modifier against a DC. Four degrees of success: critical success (beat DC by 10+), success, failure, and critical failure (miss by 10+). Each turn grants three actions to spend freely on strikes, movement, spellcasting, or other activities. Multi-attack penalty (-5/-10) discourages repeated strikes and encourages tactical variety. |

| Best For | Groups who want a deeply researched medieval European setting with the most flexible magic system in tabletop RPGs and troupe-style play where multiple characters share the spotlight across seasons of game time. | Groups who want deep character customization, tactical grid combat with meaningful turn-by-turn decisions, and a richly detailed fantasy setting with free rules. |
| Highlights | Technique + Form magic system allows freeform spell creation by combining five verbs with ten nouns. Troupe-style play rotates magi, companions, and grogs so every player has multiple characters. Covenant management adds strategic play between adventures. Mythic Europe setting blends historical accuracy with medieval folklore and theology. | Complete rules available free on Archives of Nethys. Three-action economy gives every turn meaningful tactical decisions. Character customization through ancestry feats, class feats, skill feats, and general feats at every level. Four degrees of success on every roll add granularity to outcomes. |
| Considerations | Core rulebook is dense at 240 pages with extensive magic subsystems that require study before play. Laboratory rules, seasonal advancement, and covenant management demand significant bookkeeping. The troupe-style format requires buy-in from the whole group. Combat is deliberately secondary to magic and social play. | New players must learn the trait system, conditions, and four degrees of success before combat runs smoothly. Multi-attack penalty and numerous combat actions can slow turns for indecisive players. Character creation requires selecting feats from multiple categories at every level, which can overwhelm new players. |
