one of my players decided they want to take a giant wasp as a totem animal and i need help make the coming up with ideas , one of my ideas is they will be able to make unarmed attack
Bonus Action melee attack, usable only in rage 1d4+str poison damage. Target must pass a con save (based on the barbs CON) or be poisoned. Lasts up to one min or until the target saves.
Other than that just copy the Eagle totem barb. Compound eyes for enhanced vision, and the fly/jump power.
