Your Tail Stab and slashes apply acid to living lifeforms that slowly burns them, and slashes against targets with acid stacks fill your acid glands. You also gain Corrosive Acid equivalent to that of a Praetorian that you can deploy more quickly than any other caste, at the cost of a chunk of your acid reserves with each use. Finally, after a twenty second windup, you can force your body to explode, covering everything near you with acid. The more acid you have stored, the more devastating the explosion will be, but during those twenty seconds before detonation you are slowed and give off several warning signals which give talls an opportunity to end you before you can detonate. If you successfully explode, you will reincarnate as a larva again!"
