What is inside the Vampire Hunter's restricted area on Vengoth Castle?

Question

Vengoth castle has a hidden floor acessible only by Vampire Hunter's. What do we expect find there?

Answer 1

The room is relatively small, shaped like a "+", in there you can find some of the following creatures:

1. Vampires
2. Vampire Brides
3. Mutated Bats

Not many of them, should be safe for anyone above level 80. You can also find a chest with a "Blood Skull" in it. After picking it up and completing a few other requirements, you will get the achievement: Castlemania.
