Special Properties

A rope can be attached to the harpoon allowing you to pull back in as a bonus action.

Additionally, when you crit the damage roll for an attack with the Harpoon, it is stuck inside the target and if you choose to keep a hold of the rope the target is now tethered to you. While tethered if the creature is no more than one size larger than you it moves at half speed when moving away from you.

While tethered in this way you can use the Attack action to make a special melee attack to either pull the target in or knock it prone. If you’re able to make multiple attacks with the Attack action, this attack replaces one o f them. The target of this attack must be no more than one size larger than you. You make a Strength (Athletics) check contested by the target’s Strength (Athletics) or Constitution check. If you win you either knock the target prone or pull it 10 feet towards you.

At the start of the creatures turn they can use choose to make a Constitution saving throw (DC 12) to attempt to remove the Harpoon. On a successful save the tethered condition is removed and they take 1d6 piercing damage. On a failed save the creature takes half damage and the condition is not removed.
