Storm Thrower Harpoon (Patreon)

Weapon (trident), legendary (requires attunement)

This weapon has a +3 bonus to attack and damage rolls made with this magical weapon.

The trident has a chain attached to its handle that can be used to retrieve the weapon once it's been thrown using a bonus action. When you hit with a ranged attack using this weapon, it deals an additional 1d8 lightning damage.

In addition, this trident acts as a conduit for the sky's ferocious power. Immediately after hitting a creature with the trident, you can call down a bolt of lightning upon it, forcing it and all creatures within 5 feet to make a DC16 Dexterity saving throw. On a failed save, creatures take 6d10 lightning damage, or half as much on a success. Creatures have disadvantage on the saving throw if they're submerged in water or wearing metal armor. You are immune to the lightning damage caused by this effect. This ability fails if the creatures are obstructed from the sky. Once you use this ability, you cannot do so again until the next dawn.

Impale. You can use your action to try to impale and pull a creature toward you. If your target is a creature that is no more than one size larger than you, you can make a ranged weapon attack against it using the trident. If you hit, you can attempt to pull the impaled creature toward you by making a Strength (Athletics) check contested by the target's Strength (Athletics) check. If you succeed, you can pull the creature up to 20 feet toward you.

With a final, thunderous cry, Corryn hurled the trident downward. It found its mark and buried itself in the great beast's shell: finding purchase within the gashes left by her fallen comrades. From above the boat came a flash of light, followed by a deafening roar, as a pillar of white, hateful lightning pierced the Dragon Turtle, causing everything but her steeled resolve to shudder from the impact.

The surrounding water hissed and crackled as it vaporized, and the fearsome creature let out a final, defiant cry. The water calmed, and the floating carcass of V'resh the Sea Tyrant now lay resting before her: the glimmer of gemstones and untold riches now catching in the returning sun.

She waited a long moment before retrieving her trident with a flick of her mighty wrist. The storm in her heart had begun to die down, but the soft mist and spark of her great weapon would always remind her.
