I got level drained by a mummy I think. Now I've been trying real hard to get back to normal but it doesn't seem to be possible (I'm sure it is though). I've tried with dispel magic and remove curse but it won't work. I really can't run around with a level 1 paladin for too long... =) So, I'd appreciate any help I can get.

You need a restoration spell. Lesser Restoration is a fourth level priest spell. I recommend picking up Amonen because he can get this spell right away for. Its handy when fighting vampires.

theres also a priest spell called negetavie plane protection (level 4) that protects u from level drain

you can get it removed at most temples to for 1000 gold I think
