Q120: Assuming that a troglodyte has been energy drained (1 negative level) by a wight and that it has failed its saving throw. So one racial HD is gone. Could you use that kind of troglodyte as a player character race? Is it ok rules wise, cheesy or a house rule?
Troglodyte has +2 LA, +2d8 HD, +1 BAB, +6 natural armor, Multiattack(B), Weapon Focus(javelin), etc.
Q121: Could you treat that kind of troglodyte as a 1HD monster and take class levels instead of the monstrous HD (Savages Species p.13)?
Q122: If the answer is yes for Q121 then what benefits would you get? Would you gain these: +2 LA, +6 nat armor, special attacks/qualities, natural attacks and racial skill bonuses? Would you get both of those 2 feats (Multiattack(B), Weapon Focus(javelin))?
