Lol does trucks like, flip a coin a decide if you don't die when you protect?
First you're a bodyguard
Then you're a bodyguard who can protect himself (not actually how a bodyguard works)
Then you say you didn't protect anyone because you were saving it
Then you say your protection degrades over usage, and have a chance to die if you use it too much.
All of which are things that are against the wiki entry.
You're role isn't just out of the box...it's completely bizarre and mislabeled as well.
