Arcane Reflection

Whenever targeted by a spell by an enemy within 60 ft that forces you to make a DEX saving throw, you can use your reaction to reflect the spell back at them. If the spell is equal in level or lower than the spell slot used to cast Arcane Reflection, the enemy must instead make the saving throw against your DC and the rest follows the spell description.

If the spell is a higher level than the spell slot used to cast Arcane Reflection, you must roll a d20 and add  your spellcasting modifier to see whether the reflection takes. The DC equals 10 + the spell to be reflected level.
