Sundering Strike

When an ally within 300ft, including your self, rolls a natural 20 you are filled with a mysterious power.

Regardless of turn order you may launch yourself to a creature within 60ft  and make a melee attack for 1d20+20 radiant damage. If you roll a natural 20 on damage or the to hit, it triggers this ability again, twice if you rolled the 20 on both.

If you hit the attack, you may choose to push the creature up to 5x the distance you moved in a direction of your choice and the creature is knocked prone. If this kills the creature it is cut in half by your attack.
