Multiple Rulesets
A plug-in ruleset system that adapts to different d100 game variants and house rules.
Configurable Strategies
Rulesets define how the game works: characteristic generation (roll vs point buy), hit points (hit locations vs single pool), armor behavior (blocks vs reduces damage), combat complexity (standard vs simplified), and action points (variable vs fixed).
YAML-Driven Data
All game data — species, cultures, careers, skills, combat styles, weapons, spells, and more — is defined in structured YAML files. This makes it straightforward to create new rulesets or modify existing ones.
Formula System
Skills and attributes use derivation formulas like STR+DEX
that resolve against character characteristics. The formula evaluator handles arithmetic,
functions (ceil, floor, round, avg), and lookup table references.
Multiple Game Variants
Ship with multiple rulesets out of the box, covering different game settings and rule variations. Characters are always tied to their ruleset, so you can run multiple campaigns with different rules simultaneously.
