You gain a slightly weaker version of the Sting action from the Giant Wasp. It can also be used as a bonus action after a successful grapple.

Sting. Natural Weapon Attack: Reach 5 ft., one creature. The target must make a Constitution saving throw, taking 6 (2d6) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

For the saving throw DC, use 10+Half your character level.

Your wings give a flying speed of 30.

You gain proficiency with the Poisoner's Kit, and once during a Long Rest, you can use a kit to extract some poison from your stinger. This produces 3 of the "Poison, Basic (vial)" item, or one vial of poison equivalent to the "Serpent Venom" item. After doing this, you cannot use your Sting action for another 8 hours, or until you finish a Short Rest.

Waspmen live in large nests. To make these nests and get around them, they have become skilled at burrowing and climbing. You have a burrowing and climbing speed of 20.

You have a thick, hard shell around much of your body. Your unarmored AC increases by 2.
