Rune of Thirst

The weapon turns an opponent's blood and flesh into life for its master. Dwarves say it thirsts; those who carry one say it hungers.

Whenever the weapon hits, its bearer recovers HP equal to 5% of the damage dealt per rune level—5% at level 1, 25% at level 5, and 50% at level 10. Count the damage the target actually suffers after DR.

This is true healing. It never raises the bearer above maximum HP or creates a temporary reserve.

The rune drinks only living flesh. Undead, constructs, elementals, and creatures without blood or flesh cannot feed it. A bearer facing a horde of skeletons usually discovers this detail at the worst possible moment.
