Traits

Actions
Multiattack
The quavilithku makes two Bite attacks.
Bite
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) piercing damage plus 17 (5d6) poison damage. If the target is a creature, it must succeed on a DC 18 Constitution saving throw or have the poisoned condition for 1 minute. While poisoned in this way, a creature can't regain hit points. A poisoned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Dissolving Web (Recharge 5–6)
The quavilithku expels acid-drenched webs in a 90-foot cone. Each creature in that area must make a DC 18 Constitution saving throw, taking 44 (8d10) acid damage on a failed save or half as much damage on a successful one. Nonmagical objects in the area that aren't being worn or carried take 44 (8d10) acid damage.
Bonus actions
Assess Weakness
The quavilithku sizes up a creature it can see within 40 feet of itself. Until the start of the quavilithku's next turn, it has advantage on attack rolls against the creature.
