Necrotic Strike

Necrotic Strike is a new death knight ability that comes with Cataclysm, learned at level 83. It was first announced in the Cataclysm death knight preview.

Necrotic Strike deals weapon damage and applies a debuff that absorbs an amount of healing based on the damage done. "blizz"

This ability is meant to bring back some of the old flavor from when death knights could dispel heal-over-time (HoT) effects. It also gives the class a bit more PvP utility without simply replicating a Mortal Strike-style effect.
