Our How to Unlock the Goblin Cave in The Forge guide walks you through the required quests. In The Forge, there are plenty of quests to complete for EXP and other rewards. For example, The Forge Tomo’s Cat quest can only be completed once you unlock the Goblin Cave!

How to Unlock the Goblin Cave in The Forge

The Goblin Cave is a locked location that you can only access once you have a special key. But how do you get this key? Well, you need to speak with the Goblin King first and foremost.

Upon talking to him, you unlock a set of 5 quests, which rinse your pockets of Gold. As you progress through the questline, the amount of Gold the Goblin King asks for increases, as well as the ore he requests. Once you complete all 5 quests, you obtain the key as a reward, which you can then use to unlock the door of the Goblin Cave.

How to Source the Requested Ores

  • Topaz (1 in 143)
    • You can find Topaz by mining in the Forgotten Kingdom. Volcanic Rock, Basalt Vein, and Basalt Core all have a chance of dropping Topaz when mined. It’s of the Rare rarity, so it’s not too common
  • Diamond (1 in 192)
    • Diamonds are obtainable when mining in the Forgotten Kingdom. Basalt Core and Basalt Vein have a chance of dropping Diamond, and like Topaz, this ore is of the Rare rarity
  • Emerald (1 in 363)
    • To get Emeralds, you need to mine in the Forgotten Kingdom. For this ore, you need to mine Basalt Vein and Basalt Core. However, this ore is of the Epic rarity, so it’s rarer than Topaz and Diamond
  • Ruby (1 in 487)
    • Like Emeralds, the Ruby is also of the Epic rarity. To get Ruby, you must mine in the Forgotten Kingdom. Only Basalt Vein drops this ore, though!

Where is the Goblin King?

From the spawn area of the Forgotten Kingdom, head forward, facing the forge. Once you reach the forge, turn left, walk past the Runemaker and Enhancer buildings, and keep going forward. Eventually, along the path, you’ll see two Goblins holding axes.

Despite them looking like they’re blocking the path, you can actually just walk through them, leading you to the Goblin King.
