Affliction Devil (Kocrachon)

Magical darkness doesn't impede the kocrachon's darkvision.

A creature afflicted with this disease has the poisoned condition until the disease ends. While diseased, creatures gain no benefits from a long rest, gaining exhaustion when necessary. If a creature dies while afflicted with Infernal Rot, its corpse transforms into a newborn kocrachon after 4 (1d8) days.

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

The kocrachon gains a +1 bonus to attack and damage rolls for each different creature it damaged on its previous turn.

The kocrachon makes three Claw attacks. It can replace one of the attacks with a Proboscis attack.

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.

Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 10 (1d12 + 4) piercing damage plus 14 (4d6) poison damage. Creatures damaged by this attack must succeed on a DC 16 Constitution saving throw or suffer the Infernal Rot disease.
