How to Find the Infernal Heart in Prospecting?
The Infernal Heart is a hidden location added to Prospecting with the Volcanic Expansion update. It is also a time-limited location that opens for 30 minutes once every hour at the XX:15 mark. Here’s how to find the Infernal Heart in Prospecting:
- Go to Caldera Island.
- Enter the Volcano. You must complete the Fire Priest quest (find a Fire Opal) if you want to dig in The Magma Furnace and the Infernal Heart.
- Wait for the Infernal Heart to open.
- Look across from the entrance of The Magma Furnace to find it.
The Infernal Heart is full of Mythic ores like Painite, Inferlume, Flarebloom, and the Volcanic Core. It’s also the only location that has an Exotic ore, called the Dinosaur Skull. However, just like the Magma Furnace, you must have Toughness 5 equipment to be able to prospect in the Infernal Heart.
Where to Find the Quest NPCs on Volcano Island
With the Volcanic Expansion, two new NPCs have been added to Prospecting. Both of them are located on the Volcano Island, and below is everything you need to know about them:
| NPC | Location | Quest | Reward |
|---|---|---|---|
| Disgruntled Local | Standing inside a hut located across the entrance of the volcano. | Fireproofing: Collect 100 Obsidian, 100 Copper, 10 Pyronium, and 1 Cinnabar. | $5,000,000 Cash, 100,000 EXP, and 600 Shards. |
| Lightkeeper | Standing on the base of the Lighthouse behind the volcano. | Beneath the Earth: Open the lighthouse trapdoor and talk to the Lightkeeper. | $10,000,000 Cash, 122,000 EXP, and 500 Shards. |
For the Fireproofing quest, the best locations are the Windswept Beach and the Volcanic Sands. Read on to learn more about the Lighkeeper’s quest.
How to Open the Lighthouse Trapdoor in Prospecting?
To complete the Lightkeeper’s quest on Volcano Island, you need to open the trapdoor with the Volcanic Key. This is a new item that can only be found in The Magma Furnace and the Infernal Heart.
- Talk to the Lightkeeper to start the quest, and then go to the Magma Furnace to start looking for the Volcanic Key.
- Once you find it, come back and talk to the Lightkeeper again. He’ll ask you to check out what’s underneath the trapdoor.
- Now, enter the lighthouse, equip the Volcanic Key, and press E to open the trapdoor. You will lose the Volcanic Key, but the door will now remain unlocked for you.
How to Get the Fossilized Shovel, Pan, and Sluice in Prospecting?
After completing the Lightkeeper’s quest, you can now enter the hidden trapdoor inside the Lighthouse to go underground into a small chamber. In the chamber, you’ll find three tables with symbols of three different minerals on them. The minerals are:
- Uranium - Fortune River Delta, Azuralite Oasis
- Catseye - Rubble Creek Deposits, Fortune River, Volcanic Sands, Windswept Beach, The Magma Furnace
- Flarebloom - The Magma Furnace, Volcanic Sands
Place the three items on the designated tables to unlock the door and access the secret chamber, which is a maze full of hallways, rooms, and doors that don’t open.
The Fossilized Sluice is on the right side of the maze. So, from the entry point, take the last right of the hallway and go straight until you reach the end to find the Fossilized Sluice. It costs $800,000,000 and has 20,000 Luck, 200 Capacity, 5 Toughness, and 1 Efficiency.
The Fossilized Pan and Shovel are in a different room. From the main entrance, take the left path and then take the first right. Keep walking until you reach the end of the hallway and see a room on your left. There will be a bookshelf that you can move to access a secret area. That’s where the Fossilized Pan and Fossilized Shovel are.
The Fossilized Shovel has 5 Toughness, 1 Dig Speed, 40 Dig Strength, and costs $1,000,000,000. As for the Fossilized Pan, which also costs the same, you get 200 Luck, 225 Capacity, 8 Shake Strength, and 1 Shake Speed.
Catseye is a Legendary item that can be found at Rubble Creek Deposits, Fortune River, Volcanic Sands, Windswept Beach, and The Magma Furnace.
Uranium is a Legendary item that sells for $1,500,000 and is found at Fortune River, Fortune River Delta, Azuralite Oasis, and Infernal Heart.
Flarebloom can only be obtained in the Magma Furnace and the Infernal Heart. It is a Mythic rairty mineral and sells for $30,000,000 per kg.
