Just a bit of a warning for those who want to play Pool of Radiance with the Ranger and Paladin. Don't get level drained. Weird stuff starts to happen when you try to restore them. First the character's gender will cycle from male-->female-->copper-->' '. Second, the restoration spell won't actually restore the level but give the character, literally, 10,000,000 xp. This was done just using restoration scrolls so maybe GBC's Fix-Drain option will work better.
I just tested GBC's Fix-Drain option and it seems to work fine for the Paladin and Ranger. Just don't use any restoration scrolls on them.
