Welcome to the Spirit Game

Core Rules known by all spirits, and the caster.

When the caster performs a significant action of a particular alignment, the spirit(s) that are in line with that alignment gain a boon point, and the opposing alignment(s) gains +1 Permanent max mana. At 10 max mana, new traits or boons will be unlocked for that spirit.

When spirits take actions on their own, these do not directly count towards 'significant actions' but may unlock or grant them unique boons.  Enough uncontrolled actions can also grant unexpected benefits or penalties.
