Flammable

The Vile Corruption is considered flammable and ignites as if it were a flammable object. If the Vile Corruption takes more than 35 fire damage from a single attack or effect, or if it is on fire for 3 or more rounds, it explodes in a black ball of flames. Each creature within 20 feet of the Vile Corruption when it explodes must make a DC 14 Dexterity saving throw, taking 35 (10d6) fire damage of a failed save, or half as much damage on a successful one.

Magic Resistance

The Vile Corruption has advantage on saving throws against spells and other magical effects.

Shapechanger

The Vile Corruption can change its shape to match that of any beast, demon, elemental, monstrosity, or spirit at will. Its statistics, other than its size, are the same in each form. While in this form the Vile Corruption still keeps its watery appearance.

Actions

Multiattack

The Vile Corruption makes three attacks: one with its bestial bite and two with its claw mimicry.

Bestial Bite

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage. The target must then succeed on a DC 14 Constitution saving throw or have putrid water forced down its throat. On a failed save, the water enters the creature's stomach and nullifies any potions currently affecting it.

Claw Mimicry

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) slashing damage.

Avian Mimicry

Waterlogged copies of songbirds burst from the Vile Corruption and soar toward up to 3 creatures that are within 30 feet of it. Each target must make a DC 14 Dexterity saving throw, taking 11 (2d10) necrotic damage on a failed save, or half as much damage on a successful one.

description

Vile Corruption is the name given to one of the dangerous manifestations of living sicknesses that plague the eastern side of the island-A shapeshifting aquatic thing that terrorizes the Brackwater Wetlands, mimicking the creatures that live within the woodland and striking without cause or hesitation. Since its introduction to the environment, factions such as the Toraf and Boulder's sword school and the Rangers of the Greenward Path have been adamant about warning travelers to avoid the creature at all costs. Both organizations share the opinion that it is best to not get where you are going if it means keeping your life.
