Actions

• Multiattack. The grindylow makes two attacks: one with its bite and one with its claws.
• Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) piercing damage.
• Claws. Melee Weapon Attack: +3 to hit, reach 10 ft., one target. Hit: 8 (2d6 + 1) slashing damage and the target is grappled (escape DC 13). Until this grapple ends, the target is restrained, and the grindylow can't use its claws on another target.
• Ink Cloud (Recharges after a Short or Long Rest). A 20-foot-radius cloud of ink extends all around the grindylow if it is underwater. The area is heavily obscured for 1 minute, although a significant current can disperse the ink. After releasing the ink, the grindylow can use the Dash action as a bonus action.
