Physical Description

General Physical Condition

The average black pudding measured 15 ft (4.6 m) across and 2 ft (0.6 m) thick and they weighed around 18,000 lb (8.2 mt).While most of these monsters were an inky black, some could be brown, grey, and even white.In underground locations, these creatures appeared as dark blobs. Some black puddings that managed to survive for a very long time came to be known as elder black puddings, they were significantly bigger than their younger counterparts and had almost impenetrable outer layer of aged material. These ancient black puddings were immune to all damage, unless the outer layers were dissolved first by a very specific concoction.

Personality Characteristics

Motivation

These creatures were mindless underground-dwelling hunters and scavengers that wandered and absorbed whatever they found.A black pudding would position itself in a dungeon hallway like a shadow and wait for unsuspecting prey.
