Creature - Horror 5/3, 2B (3) Drinker of Sorrow can't block. Whenever Drinker of Sorrow deals combat damage, sacrifice a permanent.1 It strikes at your soul, heedless of your prayers.

If this card leaves play before it deals combat damage, then you do not have to sacrifice a permanent. If it leaves play because of combat damage or after combat damage, you do. [Legions FAQ 2003/01/23]
You only sacrifice one permanent, no matter how many things it deals damage to. [Legions FAQ 2003/01/23]
