Calamity

In reaction to receiving damage, you may use your reaction to cast this spell. When you cast this spell, all damage received until the start of your next turn is pooled and negated to you, all of the enemy's attacks seeming to either completely miss or phase straight through you. When your next turn starts, choose up to 5 attackers that damaged you within the time you pooled their damage. Those three attackers take the total pooled damage divided by however many attackers there are, as seemingly the universe causes mysterious and random consequences to unfold upon them, such as a falling brick they didn't see coming in a dungeon or a random arrow flying out from the shadows of nowhere. After all, no one escapes Calamity.

If the total damage pooled exceeds over 150 HP worth of damage, you start to receive damage that exceeds it and no more damage is pooled. This spell cannot be cast against damage from sources such as terrain damage or falling damage and any damage that does not come from a creature is still received.
