Traits

Fungal Aura

A creature that starts its turn within 5 feet of a mindrot thrall must succeed on a DC 13 Constitution saving throw or become infected with mindrot spores.

Actions

Acid Breath

Recharge 4–6

The thrall exhales a blast of acidic spores from its rotten lungs in a 15-foot cone. Each creature in that area takes 36 (8d8) acid damage, or half damage with a successful DC 13 Dexterity saving throw. If the saving throw fails, the creature is also infected with mindrot spores.

Claw

+4 to hit, reach 5 ft (1.5 m). Hit: 2d6 slashing damage.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) slashing damage.

Mindrot Spores

Infection occurs when mindrot spores are inhaled or swallowed. Infected creatures must make a DC 13 Constitution saving throw at the end of every long rest; nothing happens if the saving throw succeeds, but if it fails, the creature takes 9 (2d8) acid damage and its hit point maximum is reduced by the same amount. The infection ends when the character makes successful saving throws after two consecutive long rests, or receives the benefits of a lesser restoration spell or comparable magic. A creature slain by this disease becomes a mindrot thrall after 24 hours unless the corpse is destroyed.

Multiattack

The mindrot thrall makes two claw attacks.
