Multiattack

The tosculi hive queen makes four Scimitar attacks.

Scimitar

Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.

Stinger

Melee Weapon Attack: +11 to hit, reach 5 ft., one creature. Hit: 22 (6d4 + 7) piercing damage, and the target must succeed on a DC 17 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. The hive queen's potent poison can be removed only by the greater restoration spell or similar magic.

Implant Egg

The hive queen implants an egg into an incapacitated creature within 5 feet of her that isn't a Construct or Undead. Until the egg hatches or is removed, the creature is poisoned, paralyzed, and doesn't need to eat or drink. The egg hatches after 30 days, and the larval tosculi bursts out of the host, killing the host in the process. A creature can take its action to remove the egg by succeeding on a DC 20 Wisdom (Medicine) check. Alternatively, a spell or effect that cures disease disintegrates the unhatched tosculi.
