Shadow Pulse

You focus shadow energy and unleash it in a violent pulse in a 120-foot area around you. Enemies in that area must make a Dexterity saving throw. On a failure, an affected creature is pushed 10 feet back and falls Prone, in addition to taking 12d6 shadow damage and being unable to take any action until the end of its next turn. On a success, it takes only half the damage and is pushed 10 feet.

At Higher Levels. When you cast this spell by spending Mana points equal to a 9th-level spell or higher, the damage increases by 3d6 for each spell level above 8th.
