Sky Splitter

You raise your hand to the sky and, with a feral scream, call down a bolt of lightning. Enemies in a 20-foot-radius sphere centered on a point within range of the spell must make a Dexterity saving throw. On a failure, struck enemies take 5d6 lightning damage and have their speed reduced by 15 feet, or take only half the damage on a success.

Allies within the lightning’s area receive part of the energy in the form of an electric armor, granting them 2d6 temporary hit points and resistance to lightning damage until the end of their next turn.

At Higher Levels. When you cast this spell by spending Mana points equal to a 5th-level spell or higher, the damage and temporary hit points increase by 1d6 for each spell level above 4th. When cast as a 5th-level spell or higher, this spell’s damage becomes plasma.
