Tower Cellar Level 5

Tower Cellar Level 5 is the last level of the Black Tower and you'll find

The Countess here.

She will use

Fire Wall on the entrances to her room, but is a fairly easy kill otherwise and drops a bunch of runes. For this reason Tower Cellar 5 is one of the most farmed areas in this Act (besides Terror Zones).

The weapon and armor racks in the wings of this cellar are often farmed on Hell difficulty for base items.

Number of elite pack spawns:
Normal: 1
Nightmare: 2 - 3
Hell: 3 - 4

Superunique:
