Actions

Multiattack.

The raklupis makes a Bite attack and two Serrated Sword attacks. It can use Venom Globe in place of one of these attacks.

Bite.

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 5) piercing damage plus 18 (4d8) poison damage. If the target is a creature, it must succeed on a DC 20 Constitution saving throw or have the poisoned condition for 1 minute.

A poisoned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
