Prismatic Barrier

A shining projectile shoots out from you in a line 60 feet long by 5 feet wide in a direction of your choosing. Every non-hostile creature in the line (including you) gains 4d6 temporary hit points until the end of its next turn.

At Higher Levels. When you cast this spell by spending Mana points equal to a 3rd-level spell or higher, each creature gains an additional 2d6 temporary hit points for each spell level above 2nd.
