Displace Damage

You attempt to transfer the damage dealt on a creature from a melee attack or a ranged attack to another creature. If the attack hits by meeting the creature's current armor class or exceeding it by 1, the spell automatically succeeds.
If the attack hits the creature by more than one above its current armor class, make an ability check by using your spellcasting ability. The DC equals 10 + 3 for every additional two numbers over the creatures armor class.
On a success, a purple portal appears between the damage dealing weapon or ammunition and the creature being hit. Choose another creature other than the one who was hit within 60 feet of you or an object in a five foot space. The same portal will open up in an open five foot space next to that creature or object. Roll a spell attack roll against that creature. On a hit, that creature takes the intended damage instead.

When you cast this spell using a spell slot of 5th level or higher, the attack is automatically displaced if the attack hit by an amount equal to 2 more than the original success per level of the spell slot you used. For example, a 5th level automatically succeeds if the attack hit by exceeding the creature's current armor class by 2 or 3.
