Mythic Summon

Call one mythic spirit, avatar, dragon, guardian, elemental prince, ancestral champion, or custom legendary summon approved by the GM. It acts after your turn, follows your commands through the binding, and vanishes if reduced to 0 hit points, if concentration ends, or if its story limit is violated.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
