Barrier

You conjure a barrier of magical energy around a target you can see within range (including yourself). Your barrier spell effects all friendly targets within a 15 ft radius of the target location granting them 2d6 + your spellcasting modifier as temporary hit points. These hit points represent the magical shield protecting them. The barrier decays after 1 minute. 

At higher levels: Barrier provides 1d6 additional temporary hit points per expended spell level above 1st.
