Rookery Combat System

The Rookery Isles roll system is a d20 engine. You roll to act against a Cast DC, your target rolls a save against a Resist DC, and damage is rolled in dice. Every class runs on this one engine and differs only in its abilities and the name of its resource.

Start with the Core Rules, then read your class.
