Earthen Jab

You choose a 5-foot-square unoccupied space on the ground that you can see within range. A pillar of stone or earth 5 feet wide and up to 10 feet tall errupts from the space towards a specified direction you can see within 5 feet of it. A creature that is hit by the pillar must make a strength saving throw. On a failed save, the target takes 2d6 bludgeoning damage and is pushed 10 feet. On a successful save, the pillar is stopped at the creatures space and they take 1d6 bludgeoning damage from this spell. The stone or earth pillar created is nonmagical and persists after the spell ends with an AC of 1 and hitpoints equal to 15 + your spellcasting ability modifier.

Casting this spell at higher levels adds 1 extra pillar and +10 pillar hitpoints every 2 levels above 1st level
