When you are targeted by a melee attack within range you can use your reaction to move the attack to a wall, floor or similar surface that is within range of the attack. The attacker must make a Strength saving throw against your Spell Save DC. If they succeed they are unaffected, the attack continues as normal and the spell ends. If they fail the weapon, appendage or whatever is used for the attack, is stuck against the chosen surface - this could be warping the surface to grab it or just a force that holds it in place. If the attack is made using a weapon or object the attacker is stuck to that weapon or object, unable to let go, while affected by this spell. The target will be Restrained for the duration. The target can use an action on their turn to make a Strength saving throw - if they succeed they end the effect upon them and the spell ends.
