Multiattack. The tosculi warrior makes one Claw attack and one Stinger attack.

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (2d4 + 5) slashing damage.

Stinger. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 10 (2d4 + 5) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or be poisoned for 1 minute. While poisoned in this way, the target is also paralyzed. A poisoned target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Prepare Host. The tosculi extends the paralysis on a creature within 5 feet of it that was paralyzed by a tosculi's Stinger attack. The paralyzed target must succeed on a DC 13 Constitution saving throw or be paralyzed for 8 hours and no longer makes saving throws to end the paralysis. The paralysis ends if the target takes damage while below half its hp maximum. Otherwise, a spell or effect that cures disease ends this paralysis.
