Dome of Protection

The spell creates a 15ft sphere of protective energy Surrounding the caster granting Resistance from ranged attacks and spells. 

This spell creates a 15ft sphere around the caster. Any creatures within this sphere gain resistance too all Ranged Attacks (Magical and non magical) and Spell, and immunity to Magic Missile.

Once this Spell is cast the caster must spend their action on each of their turns to maintain the Dome of Protection and their speed becomes 0ft

If this spell reduces damage to any creature within the Dome of Protection it gains temporary hit points equal to the damage reduced to each creature. To a maximum of 50 temporary hit points. 

The caster can choose to end this spell early, when they do so they can target one creature within 60ft of the caster. That creature must make a Dexterity saving throw or take Force damage equal to the Temporary Hits points of the spell and half as much on a successful save. 

For each spell above the 5th level you can increase the sphere by 5ft and increase the max temporary hit points by 10.
