i have broken the altar but cant defeat gulnan
Like all caster battles, your best defense is a strong offense. That means a fast rush to immobilize the spellcasting. Without knowing what class(es) and level you are playing I can only suggest general tactics. Buy a few potions of both invisibility and speed. At the entrance door to Gulnan's lair, pause, buff you and your hench and with at least the 2 I mentioned, then place your hench on Stand Ground. Race straight to the back of the room to the right of Gulnan. Do NOT engage in any combat at this point.
Ignore the altar bashing. It just puts your PC at an immediate disadvantage by alerting Gulnan to your presence.
When your PC is near the back wall, pause and command your hench to Follow. As soon as it reaches your PC, change it to Attack Nearest and attack Gulnan BY MELEE. If you elect to cast spells or other range attack, Gulnan will begin casting spells and this will likely unnecessaily extend the kill shot on Gulnan giving all those annoying zombies time to reach your party.
This is a basic method to neutralize a caster's strength. Especially useful is KD, if you have it (or stunning fist, for a monk).
also she keeps putting a cursed spell on me which i cant find a potion for, any help please
Aribeth will remove any detrimental effect... or use a Greater Restoration scroll, if your class permits. If it is only a negative ability spell, a Lesser Restoration potion should cure it.
