From publisher blurb:
The third volume in our new Mythic Monsters series, Mythic Monsters: Oozes brings you a dozen and one sinister scavengers and primordial predators to torment your PCs! Twelve of your favorite oozes are here, updated for the mythic rules, and when we say updated we mean complete stat blocks, yes, but more than that every globbulent horror has its own unique and exciting new mythic abilities, from an mythic id ooze’s psychotropic vapors to a mythic carnivorous blob’s skeletal liquefaction.
This product includes mythic oozes of commonplace varieties like the black pudding and gelatinous cube, as well as variants like the electric jelly and white pudding, made far more distinct in their mythic evolutions, covering CRs from 4 to 16. In addition to a dozen familiar oozy monsters, Mythic Monsters: Oozes also includes suggested alternate rules for dealing with some common ooze abilities as they interact with the mythic rules and mythic characters. To top it all off, Mythic Monsters: Oozes introduces an entirely new 13th mythic ooze, the swift and deadly quicksilver ooze, congealed from the divine forges of the gods themselves.
