Threaded Volley

You warp the ground beneath your feet in a 10-foot radius around you, and pull three boulders from the ground to hurl them at targets within 30 feet of you. You can throw them at one target or several. Make a ranged magic attack for each boulder. On a hit, the target takes 2d8 bludgeoning damage. Terrain remains distorted for 1 minute.

You cannot cast this spell again if you are in distorted terrain. While you are in that area, you can use your bonus action to throw a new boulder by spending 1 Mana point.

At Higher Levels. When you cast this spell by expending mana points equal to a spell of 3rd level or higher, you throw an additional boulder for each spell level above 2nd. When cast as a spell of 5th level or higher, this spell’s damage becomes overwhelming.
