Counterspell: Redirect

You attempt to take control of a spell a creature in the process of casting. You must Succeed on a Arcana DC check 10+ spell level to identify the spell and take control. To be able to redirect the spell you must succeed a contested spell modifier saving through with the opposing spell caster to redirect their spell.  If the creature is casting a spell of 3rd level or lower, its spell is cast and you are able to redirect it to a different target. If it 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, you are able to redirect the spell.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the interrupted spell has no effect if its level is less than or equal to the level of the spell slot you used.
