Lifedrinker

This weapon uses the power of water to draw out the life essence of its targets. On an attack roll of 20 which is confirmed as a critical hit, this power comes to the surface, granting 25 temporary hitpoints to the wielder and dealing 25-45 damage to the target. Creatures with the Fire trait take double this damage instead.
