Return to the Seed

FEAT 17
Frequency once per month

Once per month, when you die, you can instead choose to fade away. Your corpse is swallowed by the earth, leaving behind only a seed. This seed is very fragile with an AC of 10 and only 1 Hit Point. Another creature can spend 1 minute to plant the seed in a safe space and water it. If so cared for, the next morning a tree grows from it with a single large fruit or flower bud that splits open to reveal you, alive and returned to maximum Hit Points.
