Knights of the Frozen Throne Guide
Hero PowerLifestealDeal 3 damage.
Really really strong. But it balances the crappy battlecry and expensive mana cost.
Really Great Hero Power
I'd arguably say this is the best Death Knight power. To be able to every turn deal 3 damage and heal for 3 health will never not be good.
Even better then fake "discover a spell" hero power.
Sweet Jesus. This is almost as strong as INFERNO! and DIE, INSECT!
Probably the best hero power yet... very flexible, usefull in nearly all situations
Deal 3 damage and Restore 3 health to your hero ... Well that sounds great for warlocks !
