You brandish the weapon used in the spell’s casting and make a melee weapon attack with it against one creature within 10 feet of you. On a hit, the target suffers the attack’s normal effects, and the earth quakes threateningly beneath the target’s feet until the start of your next turn. If the target willingly attacks a creature other than you before then, it immediately takes 1d6 bludgeoning damage as the earth rises up to rebuke it, and the spell ends.   The spell’s damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d6 damage to the target, and the bludgeoning damage the target takes for attacking another creature increases to 2d6. Both damage rolls increase by 1d6 at 11th level (2d6/3d6) and 17th level (3d6/4d6).
