Casting Time: 1 reaction, which you take when you see a creature within 60 feet of you casting a spell
Range: 60 feet
You attempt to redirect the spell energy used by a creature casting a spell. Make an ability check using your spellcasting ability against a DC equal to 10 + the spell’s level. On a success, the spell has no effect and the creature casting it takes 4d6 damage. If you fail your ability check, the spell has no effect, but you take the damage instead.
