Death and Decay (death knight ability)

Death and Decay is a targetable AoE ability for death knights, learned at level 8.
It is the key to AoE tanking, and should always be used on cooldown when facing two or more mobs. It should not be used against single targets, as your other attacks provide more threat. 
For DPS, it is worth using when facing large packs.
