Feat: Along the Deep River

Access Tian Xia origin, or you're a follower of Sangpotshi.

Once per year, when you die, you turn into an immaterial ball of light. After a week, you return to life with the effects of a successful (but not critically successful) 9th-rank Reincarnate ritual. You always reincarnate into a sprite, but you reincarnate as a randomly selected sprite heritage.
