I use a flamethrower while you are still down there. Diamonds are compressed carbon...and that burns well...then I sell the produced coal dust for 0.25$ (Glowstone block - dust ratio).
I take away any regen potion from you. Aswell, I hit you with antimatter until every single atom of you has been eternally annihilated.
With the help of a patented IndustrialCraft Diamond Drill I easily pierce through your mask. it breaks and your complete face is visible to everyone.
