# Harpoon

## General Description

Harpoons are essential consumable items used in regions to start a battle with a chosen opponent. Successfully harpooning an enemy first gives the player an initial advantage in combat.

## **Features**

Harpoons let players pull an opponent toward them by pressing the harpoon button in a region.

**Default Harpoon**: Players receive the basic **Grappling Hook** upon completing the tutorial.

**Unlocking**: Additional harpoons unlock when players advance through Blood Progression, tracked at the Blood Altar.

**Obtaining**: Harpoons are earned as rewards for completing in-game tasks or can be bought in sets of 5 from the Merchant, with up to 10 available in the Loadout window.

**Equipping**: Harpoons can be equipped or used through the [player’s profile](/game-info/game-systems/bazaar/player-profile.md) or [Loadout](/game-info/game-systems/region/loadout.md) menu.

**Default Fallback**: If all purchased harpoons are used, players revert to the standard Grappling Hook in their profile until they acquire more.

**Effects**: Harpoon effects apply only to the opponent.
