Arcane Redirection

When you are targeted by a single target ranged spell attack you can use your reaction in an attempt to redirect the spell off it's original course in mid air. Make an ability check using your spellcasting ability modifier the DC equals 15 + the spell's level. On a successful check, the spell is redirected up to 20ft away. If the attack spell is redirected into another creature you must make the attack roll as if you had cast the spell. On a failed check the spell stays on its original course.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the DC is reduced by 1 for each level above 3rd level.
