Resinous Tar

1-level Conjuration

A sticky layer of black liquid coats the ground in a 10- foot square centered on a point within range and turns it into difficult terrain for the duration. A creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the tar until the spell ends. A creature restrained by the tar can use its action to make a Strength check against your spell save DC. On a success, it frees itself. Resinous tar counters and dispels grease (and vice versa).
