Edit: I do have 1 question. I notice you ran a dwarf. I have had a B of a time if I dont run Elf/HE because I get Sleep-F'ed. How do you pull that off?
Always kill the spellcasters 1st if possible. Hope you get woken up via damage without dying. The only fight so far where sleep has been a big issue is the undead in the ruins but if you pop a potion of fire resistance and retreat back into the final room they come at you one at a time.
