The Pity Plead

Whenever a sole target has damaged you for 1/2 or more of your max hp you may cast this spell at them in an attemptt to stop the battle. The target must succeed a wisdom saving through or be forced to stop fighting until the spell ends. If the succeed on the save they are not forced to stop fighting however the caster will have advantage on all future charisma checks/saves for the next round against the target. 

The spell ends if you or any of your companions attemptt to attack the target.

For every level you cast the spell above 3rd you can target on more person.
