Kroshius' Infernal Core

Kroshius lays in a heap to the northeast, in the Shatter Scar Vale. Take this Fel fire and use it on his remains. The fire should reanimate the fallen infernal.

At this point, I fully expect him to kill you and any friends that you may have brought along - and trust me, you will want to bring along some friends.

If by some miracle you happen to kill Kroshius, take his infernal core and return it to Niby.
