I'm in a game where a character who had gained negative levels from resurrection. In the last session this character was again killed by a wight, and then raised as a wight. The question is do/should those negative levels stay? If they do stay how would they go about healing those negative levels, if positive energy spells inflict damage to undead. So spells like restoration would be out of the picture? Then could a negative energy spell like the wights, energy drain, or some other negative-energy-level-drain-spell cure the drained levels?
If any one could clarify this it would be very helpful, for the player and the DM. Thanks!
