Actions

Rancid Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:8 (1d8 + 4) piercing damage plus 7 (2d6) acid damage. If the target is a creature, it must succeed on a DC 12 Constitution saving throw or have the poisoned condition until the start of the sewer king's next turn.

Summon Swarm (1/Day). The sewer king chitters and summons a swarm of rats to its aid. The swarm appears in an unoccupied space within 30 feet of the sewer king that the sewer king can see. It acts as the sewer king's ally, obeys the sewer king's commands, and takes its turn immediately after the sewer king's. The swarm remains until it dies, the sewer king dies, or until the sewer king dismisses it as an action.

Bonus Actions

Skitter. The sewer king moves up to its speed without provoking opportunity attacks.

Lore

Sewer kings are hulking, monstrous rats empowered by fiendish blood. This unholy influence gives sewer kings their enormous size, supernatural strength, wicked cunning, and ability to speak.
