Core Mechanic	Make a D20 Test by rolling d20, adding relevant modifiers, and comparing the total to a target number. Ability checks, saving throws, and attack rolls use this procedure. Advantage and disadvantage use two d20s and keep the higher or lower result.	Subtract your venture (skills, spent bene from stat pools, situational modifiers) from the GM's challenge to find the number you must meet or beat on a d10. If venture meets the challenge, no roll is needed. Spending bene from the Sorcery pool casts spells and adds extra dice to magical actions (succeed if any die meets the target), but a flux result on a magic die triggers magical flux, an unintended side effect. The Sooth Deck of 60 cards plays along the Path of Suns board, and each new card shifts which colors of magic strengthen or weaken at the table.

Best For	Groups who want heroic fantasy with configurable tactical combat, broad character options, and campaigns that span multiple levels.	Groups who want long-form magical roleplaying in a surreal setting where character arcs and spellcasting matter as much as combat. Particularly suited to tables willing to invest in deep character creation and the elaborate physical components (card decks and the Path of Suns play board) that the system uses.
Highlights	Advantage and disadvantage resolve common situational effects by selecting the higher or lower of two d20 rolls. Backgrounds, classes, subclasses, and feats distribute character choices across creation and advancement. Weapon Mastery gives qualifying weapon users distinct tactical effects without replacing the action economy.	Four distinct magic orders each use different rules: Vance sorcerers prepare and cast spells learned from books, Makers craft lasting magical items through the Maker's Matrix, Weavers improvise spells by combining aggregates, and Goetics summon and bind demons. The Sooth Deck of 60 cards plays along a Path of Suns board to shift which colors of magic strengthen or weaken in real time. Character arcs are the primary advancement engine: players pursue personal goals to earn Acumen and Crux points, with arcs ranging from short stories to entire campaigns. Between-session 'side-scenes' let characters take significant actions in writing without taking up table time.
Considerations	Spell preparation, spell slots, class features, and conditions create several interacting resources for players to track. High-level characters combine many spells and features, increasing adjudication work for the DM. Bastions add a separate downtime procedure for campaigns that use the stronghold rules.	The full game uses an extensive physical-component library (Sooth Deck, multiple spell and ephemera decks, the Path of Suns board, character tomes, and stat pool sheets), all integral to play. Character creation runs eight steps across multiple chapters and typically occupies a full session before play begins. The Satyrine setting and its dream-logic surrealism are built into the rules; adapting Invisible Sun to a more conventional fantasy world requires reworking the magic registers, currency, and order structure. The Black Cube boxed set's premium pricing creates a higher barrier to entry than typical RPGs.
