Verdant Wall of Deflection

When a target within 30 ft is successfully hit with a ranged or ranged spell attack, the caster uses its reaction to create a concave 10ft high x 5ft wide wall made of lush vines and plant-life that deflects the attack. This wall has 15HP and 10 AC when targeted directly. 

Any ranged physical attack (i.e. arrows, thrown daggers, rocks) will either stick in or bounce off of the wall, rendering the attack useless, unless the total damage of the attack meets or exceeds the walls health, at which point the wall dispels and any remaining damage the attack would do affects the target. 

Any Ranged Spell/Magic attack (i.e. dragons breath attack, fireball, magic missile) will follow the curve of the wall, redirecting its energy away from the target. The attacker must succeed a DC 15 Dexterity saving throw or be affected by the spell at half damage. Any resistances or invulnerabilities the attacking creature has will still apply. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the walls HP increases by 15 for each level, to a maximum of 60 HP, and the AC increases by 2, to a maximum of 16.
