Black Knight's Tour

Blasts creatures before you with mentally-attacking aether. All creatures in a 25 foot line before you must make a WIS saving throw or be restrained for 3 rounds. Additionally, the first creature hit takes 4d6 psychic damage, and all other creatures hit take 2d6 psychic damage; damage doubles if the creature has reduced movement speed (8d6/4d6), and their movement speed returns to normal. On a successful save, creatures take half damage.
