Actions

Infestation. Melee Weapon Attack: +3 to hit, reach 0 ft., one target in the swarm's space. Hit: 10 (4d4) piercing damage, or 5 (2d4) piercing damage if the swarm has half of its hit points or fewer. A creature damaged by the swarm must succeed on a DC 12 Constitution saving throw or contract a disease.

Each time the diseased creature finishes a long rest, roll a d6 to determine the disease's effect:

• 1-2. The creature is blinded until it finishes a long rest.

• 3-4. The creature's hit point maximum decreases by 5 (2d4), and the reduction can't be removed until the disease ends. The creature dies if its hit point maximum drops to 0.

• 5-6. The creature has disadvantage on ability checks and attack rolls until it finishes its next long rest. The disease lasts until it's removed by magic or until the creature rolls the same random effect for the disease two long rests in a row.
