Chrono Splicer

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails.
On a hit, the target suffers the attack's normal effects, and the spell tethers the target to its current space until the start of your next turn. Unless the target willingly moves 5 feet or more before then, the target takes 1d8 force damage, and the spell ends.

At 5th level, the melee attack deals an extra 1d8 force damage to the target, and the damage the target takes for moving increases to 2d8. Both damage rolls increase by 1d8 at 11th level and 17th level.
