Ooze (species)

Types
Jellies do not leave corpses and do not suffer from poison or disease, they do however suffer from bleeding making it possible they are still fleshy creatures.

It also appears that they can steal minions or at least break the bonds (perhaps Verata's Gaze); which ones do so is not known.

Trivia
Jellies appear to be based on the Ooze monsters in Dungeons and Dragons.
