Vengeful Spirit

( Complete Mage, p. 48)

[General]

Your watchful spirit takes revenge on foes that have harmed you.

Prerequisite

Watchful spirit class feature (see the wu jen class in Complete Arcane),

Benefit

If you use an initiative reroll from your watchful spirit class feature, the first creature to deal damage to you in the encounter immediately takes half the damage it dealt to you. This damage is untyped, so damage reduction and resistance or immunity does not apply. Also, you gain one extra initiative reroll from your watchful spirit class feature.
