Ward of Dawn

An immobile, faintly shimmering dome springs into existence in a 10-foot radius around you and remains until it is destroyed.

When a projectile targets a creature within this dome the dome takes the damage of the projectile instead and projectiles can not be fired from inside of the dome, additionally while the caster or an ally is within the dome they have 15 temporary hit points that refresh every turn and enemies within this dome have their movement speed halved and attacks against them have advantage

This dome has 100 hit points

At Higher Levels: The domes hit points increases by 25 for each spell slot level above 5th
