Courupted Husk

Hydrophobia. This creature cannot enter water that is deeper than one foot. If it becomes totally submerged in water it becomes incapacitated, and takes 1d10 force damage every turn.

Corrupt. 

Upon activating this trait, the creature willingly destroys itself, dissolving into a bubbling puddle of corrupted biomass that immediately spreads to cover a 15-foot square area centered on its original position (i.e., within 5 feet in all directions). This act is irreversible—the creature ceases to exist as its animating corruption disperses to seek new hosts.

At the end of the following round, the puddle animates a number of nearby humanoid corpses based on a roll of 1d4 + 1. Each Medium humanoid corpse counts as one target. Small humanoid corpses count as half a target (two Small corpses equal one Medium). Tiny corpses are ignored for this purpose.

All animated creatures rise as corrupted units of the same basic type as the creature that initiated the corruption, regardless of the strength or magical potential of the corpse.

Corpses that were previously corrupted and destroyed cannot be animated again.

Slashing Arm. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage.
