Vahn's Spell Reflection

You sense the weave shaping itself around you. When targeted by any instantaneous spell of equal or lower level (fireball or cone of cold for example, but not cloudkill), you may use your reaction to invoke the unbridled fury of an ancient chromatic dragon to snatch the weave and bend it to your will. You may completely nullify and redirect the spell to any location within range as if you had cast it. If there is a saving throw associated with the spell, the spell is treated if you had cast it.
