You hurl a ball of condensed grease at a point with range. Once thrown the ball of grease rapidly expands covering the ground in a 10-foot radius centered on the point of impact. Each creature standing in the area must make a Dexterity saving throw or take 3d8 bludgeoning damage and fall prone. On a successful save, the creature takes half damage damage and remains standing.

After which, until the start of your next turn, the grease remains on the ground turning it into difficult terrain. If a creature enters the grease or ends its turn there, they must also succeed a Dexterity saving throw or fall prone.

At Higher levels: When you cast this spell using a spell slot of 3rd level or higher, the radius of the spell increases by 5 feet for each slot level above 2nd.
