Devilish Hunt

A favorite of torturous fiends and hungry fishermen.
You conjure three barbed harpoons of intricately twisted silver.
They float in the air above your head for the spell’s duration, and
fade when it ends. When you cast the spell, and as an action on each
of your subsequent turns, you can make a ranged spell attack to hurl
a harpoon at a target within 90 feet of you. If you miss, the harpoon
fades. If you hit, the target takes 2d6 piercing damage and must
make a Dexterity saving throw. If they fail, the harpoon lodges in
their flesh.
While a creature has been skewered by a harpoon, its speed is
halved, and you can use a bonus action to cause an invisible chain to
pull taut, hauling the creature 10 feet towards you for each harpoon
lodged in it. The target can use an action to pull any number of
harpoons out, taking 3d6 necrotic damage for each harpoon removed
and causing the harpoon to fade. Once all three harpoons have
faded, the spell ends
