1. The vampiress. Finish her mission. The Scroll of Banishing, which she sent you for, will not let her and her vampiresses out. After bringing the scroll, you will be offered:
- to become a vampire (you can decline it) and
- one of two rewards (a key and a ring)
I am speaking about it because it's good to know which reward to choose in advance.
a) The key: It opens the level 12 five star lock in the castle. The lock can be picked. If you are able to pick the lock yourself (only one such lock is in the Castle) then do not choose the key. Otherwise, choose the key - the chest behind the lock contains good stuff [img]smile.gif[/img]
b) The ring: You can sell it for, IIRC, about 17000 gold. Do not try to wear the ring. It crashes the game. Sell it.
After finishing the quest and getting your reward, you can kill all vampiresses there. If you do it now, you do not get your reward. Well, you do not spoil anything by killing the vampiresses now.

2. I don't think you'll be able to kill G'Ezzered Ra. He has a role later in the game. I've never tried killing him. I recommend to bring the Holy Relic to him. He will give you the staff. Beware! If your inventory is full, the staff will be dropped on the ground instead of being placed in your inventory! Check yourself whether you have the staff! You will need it at Anephas Shrine as the lich has said to you.
You will be able to help the lich later - in the Pyramid.
