Mark of Vengeance

(Dragonmarked, page 143, DnD 3.5)

[General]

Your aberrant dragonmark strikes at the hearts of dragonmarked foes you attack.

Prerequisite

Any aberrant dragonmark

Benefit

When you make a successful melee attack against a creature that bears a true dragonmark, you deal an extra 1d6 points of damage and heal an equivalent number of hit points yourself. This is a necromantic effect.
