Description

The Abyssal Corroder was born from the fusion of the Plane of Water and the Abyss, wielding corrosive power not for destruction,
but to dissolve stagnation and make way for renewal. Though feared as a bringer of ruin, it follows a natural instinct to cleanse corrupted lands,
ensuring that from decay, new life can emerge.


While many elementals are bound to a specific natural force, the Abyssal Corroder exists as a pure manifestation of corrosive energy,
dissolving everything in its path.
Its body drips and churns as it moves, eroding the ground beneath it with each step.

Its attacks bypass armor, melting even magical defenses, making it a fearsome foe.
However, those who understand its purpose may find it to be a powerful ally in restoring balance to decaying lands.
