Deathless Predator

Become a near-complete vampire predator. You are immune to poison damage and the poisoned condition, resistant to necrotic and nonmagical weapon damage, do not breathe, and gain a climbing speed. While in dim light or darkness, your regeneration from Vampirism powers increases by your CHA modifier.

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