Armor of the Grave

The cleric tosses a pinch of bone dust into a cloud and steps through coating their body in a white glow and hardening their bodies with magic infused white glow. This eerie glow gives a plus 1 to AC and whenever the cleric is hit in combat by a melee attack, the attacker must succeed a wisdom saving throw or become frightened of the cleric for 1 minute. The frightened creature can reattempt the saving throw at throw at the end of each of its turns, ending the effect on a success.
