Death Wish

You call upon Death itself, summoning the reaper into the battlefield. You target a creature or any other kind of living being within range (it does not matter how many hit points any of the two have or how much powerful one is), the reaper puts your and the target’s souls in a balance.

Roll a d20. If the roll is an even number, the target dies. If the roll is an odd number, you die. Death itself takes the soul of the unlucky one, destroying its body. This is the ultimate death, only a wish would be able to bring back a soul taken by the reaper.
