Location
You will be heading to Kohana Island by boat, and while the Kohana event is active the island location is marked on your HUD, making it easy to navigate to the right place.

Once on the island, follow a water channel to a cave entrance that leads into the volcano interior where the charm station is located.
How to get the Magma Charm step by step
Step 1: Travel to Kohana Island
Use your boat and head toward Kohana Island. During the Kohana event, the island location is marked on your HUD, so you can follow that marker to arrive quickly.
Step 2: Move through the island toward the water channel
After you arrive, walk past the cabins and enter the water channel that runs through the island. Stay in the channel and keep moving forward.
Step 3: Reach the cave entrance at the end of the channel
Follow the water channel until you reach a cave entrance at the far end. Enter the cave and continue forward until it opens into the volcano interior.

Step 4: Find the lava fisherman area inside the volcano
Once inside the volcano interior, look for the lava fisherman NPC. This area is your main landmark before you make the final turns to the charm station.
Step 5: Cross the wooden bridge and take the first right
Near the lava fisherman NPC, you will see a wooden bridge. Cross it, then take the first right turn.
Step 6: Locate the charm station platform and buy the charm
After the right turn, look to your left for a special platform with a charm station.

Buy the Magma Charm there for 20,000 coins.

How to equip and use it properly
Step 1: Equip the Magma Charm from your inventory
Open your inventory, switch to the Charms tab, and equip the Magma Charm.

Step 2: Only keep it on for Magma Shark attempts
Because the charm only boosts the Magma Shark, it is not useful for general fishing or other targets, so equip it only when you are actively hunting that fish.

Step 3: Make sure you can access the right Magma Shark area
The Magma Shark is found in the Kohana volcano area that requires a hazmat suit, which means you need to complete the required quest before you can fully use this charm for its intended purpose.

What makes Magma Shark hunting harder than getting the charm
Buying the charm is the easy part, but catching the Magma Shark is harder because it lives in a dangerous zone and you will need strong gear and good preparation to fish there consistently. If you are serious about completing your collection or pushing late-game progress, this charm is still considered essential for the Magma Shark grind.
If your goal is the Magma Shark, the Magma Charm is the most direct upgrade you can pick up because it specifically boosts that one catch. Grab it inside Kohana Volcano for 20,000 coins, equip it from the Charms tab, and focus your sessions on the hazmat-suit volcano area once you have completed the required quest.
