I started a new character....
I found out something i didnt even know.
When in the lowest catacomb area..after you speak to the skeleton Desmond and before you pull the lever to ressurect the Necromancer..if you talk to the other skeletons,they will give you items.
I got a small healing potion,gold and a dagger.
For fun i talked to all of them, one of them was a merchant in Verdists,killed by Pembura, one was a female trying to be my girlfiend(lol).
War Drummers- you can also force them into a corner,they will start fighting you and hence not be able to heal.
