Chaos oozes are heaps of chaos-protomatter, incorporating a dozend of so eyes and mouths of different sizes and types. they roam dungeon corridors in search of prey. When lying in wait with their eyes and mouth shut, they can be taken for heaps of earthly materials. Chaos oozes are sometimes created by magical experience gone wrong, when creatures are suffused with pure chaos energy their bodies and minds cannot withstand. Such poor creatures melt away into near nothingness, leaving only a few semi-intelligent remnants behind: the chaos ooze whose sole existance is reduced to kill and eat.
Devour
A chaos ooze attacks by extending and biting with 6 mouths per round. Each mouth which hits will fasten on and drain an additional 1 point of damage per round attached. When 3 or more mouths are attached to a single character, that person must make a saving throw va. paralysis or slip and fall prone. If the character falls, the gibbering mouther will flow over the victim with its next action and automatically bite with 12 more mouths.
Confusion
When any edible object is sighted by a chaos ooze, it may begin an incoherent gibbering that causes confusion (as the spell) in all characters within a 20’ radius unless a savevs.spells is made. For each round that monster is heard, characters within range must roll another save.
Note
The brain of chaos ooze is located in its mid-portion, and its gelatinouslike body makes it difficult to strike this one vital spot; thus its armor class of 9.
