Holy Book

Create your own sacred text and then guide a prophet who is bound by it. Your holy book is effectively a skill tree which you write. The skills (or "verses") in it trigger automatically based on trigger conditions you choose. Common triggers will make your limited charges run out faster. Some triggers are easier to control than others. These verses can deal ranged damage, heal you, apply buffs and debuffs, and summon monsters. Verses can retrigger each turn (for free) and the chance to retrigger increases with how many skills already triggered.
