Corrosive Ooze Giants
Corrosive ooze giants are a hulking variant of sentient ooze that stands about 15ft. tall. Unlike the ooze giant progenitor, these ooze giants known to develop naturally when certain species of ooze that evolved a primitive level of sapience. Although common depictions of corrosive ooze giants resemble that of a large bipedal slime monster, corrosive giants have been known to take a variety of different forms. Some assume their classic amoeboid shape, but many replicate the appearance of creatures in its environment resembling a slimy copy of a dragon, a worm, or other creature suitable to its biome.
Ravenous Hunger
Despite their heightened intelligence, ooze giants are still subject to their massive appetite and will patrol wide berths to find enough food. Thanks to the extremely acidic nature of its slime, the ooze giant is able to eat through nearly any form of organic matter. Because of their strength, limited intelligence, and versatility, it is not uncommon for ooze giants to find themselves in the services of those who are willing to trade food for their aid.
Corrosive Nature
As their name suggests, corrosive ooze giants have the ability to dissolve any nonmagical substance. As a result, adventurers must be extremely cautious when fighting these entities as they are able to fully dissolve any form of nonmagical weapon or gear that they may possess. A single touch from this hulking ooze is enough to drench their opponent in burning acid that not only continually eats away at one's skin but will melt any non-magical possessions in their grasp. Not only must one evade the ooze giant’s flailing pseudopods, but they also must also watch their footing lest they step into a trail a bubbling acid left in the ooze's wake.
Dissolving Bile
However, their deadliest attack is their ability to eject a spray of vitriolic acid onto creatures within range. The slime stored within its body, is much more potent than the ooze found in its ectoplasm. If one is not careful, this corrosive acid will completely dissolve every aspect of the victim leaving nothing but a bubbling pile of ooze.
