Wrath of Osha

Disclaimer: This spell is derived from the Wrath of Nature spell. It was specifically modified for the homebrewed Osha Domain Cleric subclass. Please speak with your GM before adding this to your spell list. 

You call out to the spiritual power of Osha to rouse them against your enemies. Choose a point you can see within range. Her power causes roots, rocks, and grasses in a 60-foot cube centered on that point to become animated until the spell ends. 

Grasses and Undergrowth. Any area of ground in the cube that is covered by grass or undergrowth is difficult terrain for your enemies. Each time they move within the cube, they must succeed on a DC Dexterity saving throw equal to your spell save DC. If failed they are restrained and can make a strength save to break free at the start of their next turn. 

Roots and Vines. At the start of each of your turns, each of your enemies within 10 feet of any tree or shrub in the cube must succeed on a Dexterity saving throw or take 4d6 slashing damage from whipping roots or vines. 

Rocks. As a bonus action on your turn, you can cause a loose rock in the cube to launch at a creature you can see in the cube. Make a ranged spell attack against the target. On a hit, the target takes 3d8 nonmagical bludgeoning damage, and it must succeed on a Strength saving throw or fall prone.
