His Grace.

[Bob]

Basically, add his grace from ss13. Its a 20 TC chaplain item that looks like a toolbox, once you interact with it you awaken his grace. His Grace does 25 Damage, once you crit someone you can eat that person by hitting them in crit. His Grace will hunger, if its hunger is at its peak it will simply eat the one holding it. You are also immune to stuns. Once his grace ate 20 people you ascend, his grace will constantly heal you, his grace wont starve anymore, and it will only take 1 hit to crit an unarmored person.
