I am about to play an undead character with a level drain ability, and I think I need a little clarification. From what I've read so far, Level Drain effects actually bestow a thing called a negative level. These negative levels reduce Saving Throws, Attacks, Skill checks, and ability checks, and incur a -5 hp. My question is about feats and Spellcasting. 1. Do negative levels affect feats? 2. Taking a wizard, level 3 with 14 Int. This wizard should be able to cast 2 level 2 spells (1 from his level, one from intelligence). If he is bestowed a negative level, can he still cast second level spells?
