You attempt to redirect a spell cast by a creature you can see. If the creature is casting a spell of 3rd level or lower, you can redirect the spell. If the spell involves a ranged spell attack, you can cause the ranged spell attack to target a different target of your choice within 10 feet of its original target. If the spell has an area of effect, you can shift the area of effect up to 10 feet in any direction. If the creature is casting a spell of 4th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a success, the creature’s spell is redirected as described.
