Blox Fruits Roblox has a massive world of sea-faring adventures and rare items. If you’re aiming to unlock the powerful Shark Anchor weapon, your journey starts with crafting a key item: the Monster Magnet. This Mythical material is the only way to summon the Anchored Terrorshark, the boss that drops the Shark Anchor.
Unfortunately, you can’t buy the Monster Magnet anywhere in-game. Instead, you’ll need to collect rare materials, craft prerequisite items, and complete several Third Sea challenges to unlock it. Here’s a complete guide on how to get the Monster Magnet in Blox Fruits.
How To Unlock Monster Magnet

The Monster Magnet is not found in shops or enemy drops, it must be crafted through the Shark Hunter NPC, which is located on Tiki Outpost in the Third Sea.
But before you can craft it, you’ll need to first create two prerequisite accessories: the Shark Tooth Necklace and the Terror Jaw. Here’s what you’ll need to gather for both:
Accessory | Materials Required |
---|---|
Terror Jaw | 1x Terror Eyes, 2x Mutant Tooth, 5x Shark Tooth, 10x Fool’s Gold |
Shark Tooth Necklace | 1x Mutant Tooth, 5x Shark Tooth |
Craft both items at the Shark Hunter NPC. Once you do, the Monster Magnet crafting recipe will be unlocked. Now, collect the following resources to craft the Monster Magnet itself:
Item | Quantity | Where To Find |
---|---|---|
Fool’s Gold | 20 | Dropped in Ship Raid, Haunted Ship Raid, and Ghost Ship Raid |
Shark Tooth | 10 | Dropped by Sharks in Sea Danger Levels |
Electric Wings | 8 | Dropped by Piranhas |
Terror Eyes | 2 | Dropped by Terrorsharks |
Once you’ve gathered all these, return to Shark Hunter on Tiki Outpost and craft the Monster Magnet.
How To Use Monster Magnet In Blox Fruits
The Monster Magnet is a single-use material that allows you to summon the Anchored Terrorshark, a level 2,000 boss with 195,000 HP. This fearsome sea beast has a guaranteed drop: the Shark Anchor, a powerful Legendary sword.
To use the Monster Magnet:
- Equip it in your inventory.
- Sail to a Sea Danger Level (Levels 3 to 6 are recommended for higher spawn chances).
- Wait for the message: “Your Monster Magnet has attracted an irregular beast…”
This signals the appearance of the Anchored Terrorshark. Be prepared—the boss hits hard and despawns if not defeated quickly. If you’re in a group, only the player whose Monster Magnet triggered the spawn will receive the Shark Anchor.
The Monster Magnet has no other use and disappears whether you succeed or fail. So make sure you’re ready before heading into battle!
