Bloody Wager

You point at a creature and make a wager with death, then touch the target of the heal. Immediately take 1d6 necrotic damage as you place your ante. This damage cannot be reduced, mitigated, or shared in any way. If the creature you gambled upon dies before the end of your next turn your target heals 2d6 + spell casting ability modifier hit points.

If the target does not die before the end of your next turn, you lose the bet and the spell ends with no further effects.

Casting at a Higher Level: When cast at 2nd level or higher, for each spell level higher then 1st, increase the initial damage done to the caster by 1d6 and the healing done on target death by 2d6.
