The bloater is a zombified corpse at the point of corruption when the body swells with foul gas and ichor. It is all too easy to hit (AC 9 descending/10 ascending) and moves extremely slowly (move rate 3). But it is robust (2+4 HD), attacks with both hands to claw and strangle (2d4 damage) and has a special defense. When hit for more than 4 hp damage, foul ichor sprays out, and the monster rolls an extra "to hit" with an extra +2 against the attacker. Success means the ichor burns the attacker for an amount equal to the amount dealt by his or her own attack, minus 4. Also, the victim must save (Fortitude/Poison) or contract a disease that picks a random ability score and drains 1 point/day until cured.
