This rare subspecies of bloat is filled with a peculiar vapor that, if released, will cause the floor to vanish out from underneath it.
A Pit Bloat dies when it attacks. When a Pit Bloat dies it releases a heavy vapor that acts as a potion of descent. An irregular hole will appear in the ground and anything that was there falls through to the next level. This hole seals itself over the next few turns. By destroying pit bloat from a distance, in strategic locations you can put out fires and avoid totems, among other helpful things. Beware, any potions that fall through the floor will be destroyed!
