So, I was happily running through the Battle Squares with my Fighter/Rogue/Barbarian, smiting everything that appeared in about three hits.. when suddenly I get hit with Energy Drain.. I know how to get rid of it with the Restoration spell, but I was wondering - what does it actually do?
[edit] Note to self - read manual. "-1 to hit, -1 to saves and -5 Max HP per 'level' drained"
