Thorn Shield

As an incoming attack happens, you call forth nature to retaliate.  A shield made out of thorns appears as you are about to get hit, causing all creatures around 10 feet of you to make a DEX saving throw or take 3d8 piercing damage in a failure. In a successful saving throw, they only take half of the damage rolled.

At Higher Levels: For each spell level above 1 that you cast the spell, the damage increases by 1d8.
