Termite Territory

The ground in a 20-foot square at a point within range erupts as two dozen termite mounds sprout from nowhere, growing around and over anything in the area. For the duration, these mounds turn the ground in the area into difficult terrain. The mounds do not provide cover.

A creature in the area when you cast the spell must succeed on a Strength saving throw or become trapped when the mound grows around them, causing them to become restrained until the spell ends. A creature restrained by the plants can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

When the spell ends, the termite mounds crumble to dust.
