Harpoon

She Took That Ship In Tow

"Any fool can kill a whale. The trick is convincing two hundred tons of dying anger to come close enough for the harpoon to matter."

— Benath Hillheart, whaling master of the Northwind

Long before it found its way into the hands of adventurers, the harpoon was a tool of survival. Designed to strike creatures too large, too dangerous, or too distant to approach directly, it has been carried aboard fishing vessels, whaling ships, river barges, and coastal expeditions for centuries. Unlike an ordinary spear or javelin, a harpoon is built not merely to wound, but to stay embedded. Its broad barbed head resists removal, while a sturdy shaft provides the leverage needed to drive it deep into thick hide, scales, or blubber.
Most harpoons are used with a length of heavy rope secured to the weapon's butt. Once the point finds its mark, the attached line allows hunters to track exhausted prey, prevent escape, or draw smaller creatures toward waiting hands. Against truly colossal beasts, however, the rope serves an entirely different purpose. Rather than hauling the quarry to the hunter, it often becomes the only thing preventing the hunter from being dragged across the sea.
The harpoon remains a familiar sight throughout coastal settlements and aboard nearly every vessel that expects to encounter large marine life. Sailors prize it for hunting whales, giant fish, sea serpents, and other creatures that would ignore arrows or snap ordinary fishing tackle with ease. River folk employ smaller versions against monstrous crocodilians and oversized fish, while monster hunters occasionally adapt the weapon for pursuing wyverns, rocs, or other massive beasts when flight or sheer strength makes escape likely.
Though undeniably capable in battle, the harpoon has never been considered a soldier's weapon. It is cumbersome, difficult to throw accurately, and poorly suited to the rapid exchanges of a battlefield. In the hands of an experienced hunter, however, it becomes something far more terrifying than a spear. It becomes a promise. Once the barb bites home and the line goes taut, the hunt is no longer about striking the quarry again. It is about enduring until one of you finally stops pulling.

Barbed Tether. While holding both the harpoon and a Rope, you can take a Utilize action to attach the Rope to the harpoon. You can similarly detach the Rope from a harpoon you are holding. The Rope is purchased and carried separately.
When you hit a creature with a ranged attack using the harpoon while holding the free end of the attached Rope, you can cause the harpoon to lodge in the target, provided the target is within the Rope’s length. While lodged, the harpoon can’t be used to make attacks.
While holding the free end of a Rope attached to a lodged harpoon, you can take a Bonus Action to reel in the target if it is Large or smaller. The target must make a Strength saving throw against a DC equal to 8 plus your Proficiency Bonus and your Strength modifier. On a failed save, the target is pulled up to 10 feet straight toward you.
This movement can’t lift a grounded creature into the air, though it can pull a creature that is already flying, falling, or swimming.
Holding the Rope requires a free hand. The tether doesn’t otherwise restrict the movement of either you or the target. If the distance between you and the target ever exceeds the Rope’s length, the Rope is pulled from your grasp. Securing the Rope to a creature or object doesn’t allow you to use Reel In and doesn’t restrict the target’s movement under this property.
The target or another creature within 5 feet of it can take a Utilize action to make a DC 10 Strength (Athletics) check, removing the harpoon on a successful check. Once removed, the harpoon falls in the target’s space.
Normal rules for damaging or bursting the attached Rope still apply.
