Drizzile (5e Creature)
From D&D Wiki
Small elemental, any alignment
Sniper. The drizzile scores a critical hit on a roll of 19 or 20 and rolls the damage dice three times, instead of twice. Additionally, attacking at long range doesn't impose disadvantage on its ranged weapon attack rolls.
Multiattack. The drizzile makes two water pulse attacks, and uses focus energy if it can.
Water Pulse. Ranged Weapon Attack: +6 to hit, range 180 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
Laser Focus (Recharge 5-6). The drizzile's next attack that hits automatically results in a critical hit.
