You create a sword-shaped plane of force that hovers within
range. It lasts for the
duration.
When the sword appears, you make a
melee spell attack against a
target of your choice within 5 feet of the sword. On a hit. the target takes 3d10
force damage. Until the spell ends, you can use a
bonus action on each of your
turns to
move the sword up to 20 feet to a spot you can see and repeat this
attack against the same target or a different one.
