Shambling mounds, or "shamblers," are found in dismal marshes or
certain wet subterranean places. They are omnivorous, feeding upon any
living material (via their weird roots and tendrils). They attack fearlessly,
clubbing with their limbs twice per melee round. If both of a shambler's
clubbing attacks hit a single opponent, the victim is entangled and will be suffocated in the creature's slime in 2-8 melee rounds unless the creature is killed.
The brain of the shambler is located in its mid-portion, and its thick fibrous layers make it difficult to penetrate to its only vital area. In fact, most hits upon it do but little damage (thus armour class 0). As it is wet and slimy, fire has no effect, lightning causes it to grow (add 1 hit die), and cold does either one-half or no damage due to its vegetable constitution. All weapons score only one-half damage. It can flatten itself, so that crushing has small effect. Spells which affect plants are effective against shambling mounds, plant control and charm plant being good examples.
Description: Appearing as a heap of rotting vegetation, the shambler is
actually an intelligent form of vegetable life. It is generally from 6' to 9' in
height, with a girth of about 6' at its base and 2' at its summit
