Magic Harpoons

Magic Harpoon Spears

Battle Anchor

Harpoon spear, rare

Only the mightiest of nautical warriors can wield this massive anchor. This weapon has the heavy and two handed properties, its attacks deal 2d6 piercing damage, and creatures wielding it must have a Strength of 14 or higher to make attacks with it without disadvantage.

When you strike a creature with the anchor, you can choose not to tether it and instead deal bludgeoning damage rather than piercing. If a creature dealt bludgeoning damage this way is Huge or smaller, it is knocked back 10 feet.

Additionally, a Huge or smaller creature tethered by the anchor moves at half its speed.

Combat Angler's Fishing Rod

Harpoon spear, rare

This weapon takes the form of an enchanted fishing pole. As an action, you can add rope to the pole, which then automatically creates a fishing hook at the end.

This weapon functions like a normal harpoon spear with the following exceptions:

• Ranged attacks made with this weapon are made by throwing the fishing hook out at targets rather than throwing the weapon itself, though it can still only tether one target at a time and can't be used to make attacks while it is tethering a target.
• The distances for ranged attacks made with this weapon increase to 60/200.
• Melee attacks made with this weapon deal bludgeoning damage rather than piercing and cannot tether targets.
• Whenever a creature you can see makes a bite attack, you may use your reaction to make a ranged weapon attack against it with this weapon. If this attack hits, the creature has disadvantage on the bite attack. You cannot make this attack if you already have a creature tethered with the pole.

Threading Needle

Harpoon spear, rare

This giant magical sewing needle is said to have been crafted by eccentric fey lords. When you tether a creature with this weapon, the needle pierces through the target, and if you have a free hand, you may have it automatically fly back to that hand while keeping the target tethered with magical thread.

Maintaining the tether still occupies one of your hands. However, you can tether additional creatures with this needle, and each tether made with the needle can be maintained with the same hand. The needle deals an additional 1d6 piercing damage per creature it is tethering.

Each tethered creature must still stay within 60 feet of you to maintain the tether. If a tethered creature succeeds on a check to pull you by the tether, rather than pull you or snap the tether, it magically moves through the thread and frees itself.

If the tether is cut, each tethered creature is freed. You may use an action to reapply a rope to the needle, which turns the rope into more magical thread.

Underworld Skewers

Harpoon spear, rare (requires attunement)

These ghastly harpoons are said to be forged in the underworld and made for hunting wayward spirits. The harpoons come in a set of 10 that are all bound to a quiver. To attune to them, you must be in possession of the quiver, and while attuned, you can use an action to cause all the harpoons to reappear in their quiver.

These harpoons can tether incorporeal creatures normally immune to the grappled condition, and the tethers attached to these harpoons take on a ghostly quality and cannot be cut, though they can still be snapped through Strength checks.

While one or more of these harpoons are impaled in any creatures within 60 feet of you, you may use an action to call all the harpoons back, causing them to rip themselves free and deal their weapon damage to the creatures they were impaling before flying back to their quiver. The harpoons phase through all obstacles to reach their quiver.

Harpoon Gun

ranged weapon (martial, crossbow)

• Damage: 1d6
• Damage Type: Piercing
• Properties: Ammunition (range 30/120), harpoon,
  loading, special
• Cost: 90 gp, ammo: 2gp (1gp for the bolt, 1gp for the rope)
• Weight: 4 lb

Harpoon Spear

melee weapon (martial, spear)

• Damage: 1d6
• Damage Type: Piercing
• Properties: harpoon, thrown (range 20/60), special, versatile (1d8)
• Cost: 2 gp (1gp for the spear, 1gp for the rope)
• Weight: 4 lb

Harpoons. You can choose to tether yourself with a rope to a creature or object you hit with the harpoon; otherwise, you can pull the harpoon back to yourself as an object interaction. A creature cannot be tethered if it immune to the grappled condition. If you choose to tether yourself, the hand you used to make the attack becomes occupied maintaining the tether. You cannot maintain multiple tethers in one hand, and creatures immune to the grappled condition cannot be tethered.

Once per turn, you can make an opposed Strength check against a creature you have tethered (no action required). On a success, you can drag the tethered creature towards you. Doing so uses up 5 feet of movement for every 5 feet you drag it unless the creature is two or more sizes smaller than you. A tethered creature can attempt to do the same to you on its turn, though if you fail the opposed Strength check, you can choose to drop the tether rather than be dragged by it. Any time an opposed Strength check is made between you and a tethered creature, if both of you roll a 12 or higher on this check, the tether snaps.

Any creature within 5 feet of a tethered creature (including the tethered creature) can use an action to remove the harpoon. Doing so deals an additional 1d6 weapon damage to the creature as the harpoon is removed. Dealing 5 slashing damage to the tether (AC 10) also snaps it.

If you recover a harpoon spear or a harpoon gun bolt with a snapped rope, you can replace the rope over 10 minutes, using 1gp worth of rope and other supplies. This can be done over the course of a short or long rest.

New Feat: Harpoon Master

You've learned how to use harpoons to maximum effect in combat. When you take this feat, you gain the following benefits.

• Your Strength or Dexterity score increases by 1, to a maximum of 20.
• Creatures you've hit with harpoons have their speed reduced by 15 feet until they've removed the harpoon.
• If a creature is concentrating on a spell and ends its turn while impaled by a harpoon you hit it with, it must succeed on a DC 10 Constitution saving throw to maintain concentration.

Rope Quality for Nets & Harpoons

Players can gain access to higher-quality rope for nets and harpoon tethers by paying more gold. The following table describes the gp cost for each level of quality. Each table row can be used to describe a net or the rope and supplies needed to attach a tether to a harpoon. In the case of nets, the gp cost describes the overall cost of the net. In the case of harpoon spears and gun bolts, the gp cost describes the added cost of upgrading the item's quality, which can also be done when replacing a snapped tether.

Rope Qualities

Cost	Break DC (Harpoon)	Break DC (Net)	Rope AC	Cumulative Damage to Cut
1gp	12	10	10	5
50gp	15	13	13	10
200gp	18	16	16	15
