Kill me, damn you!

You have lived by the sword and now you'll die by the sword, if you have anything to say about it. 

You may activate this feature when you have 10 HP or less remaining, and the ability automatically drops if you exceed this HP cap. 

While active, attacks made against you are done so at advantage, as you throw yourself into your potential final moments. During your frenzied state, your deal critical hits on a die roll of 15 or higher.
