The caster must have rocks, stone or solid ground nearby to cast this spell. When casted, four rock slabs start floating around the caster, providing cover. 4 square feet of the area where the material was taken is turned to difficult terrain.
Slabs can be then thrown, each one making 1d10 bludgeoning damage on a successful hit. Slabs can be thrown all at once or a smaller number each action to one or several enemies you can see within 60 feet until all slabs have been thrown.
While active, each rock provides cover, boosting the casters AC. Four rocks give +5 AC, and each time a rock is thrown it reduces de AC by one, with a single rock giving +2 AC.
When casted at a higher level, each level higher than 3 provides 1d10 extra bludgeoning damage per slab.
