Bomb Vest

In a server that I ran/was on, there was a meeting between two leader. I disliked both of them and tried placing tnt and lighting it, but it took too long. So I made a mod that lets you craft and detonate a bomb vest.

It blows up the moment you right click and takes you and everyone around with it.
You craft it by taking one leather tunic and surounding it on four sides with tnt.
