How to unlock the Goblin Cave in The Forge
Step 1: Reach the Forgotten Kingdom
You must first unlock access to the Forgotten Kingdom by progressing through the main storyline. This typically happens once you’ve advanced past early mining zones and gained access to portal travel.
Step 2: Locate the Goblin King
Inside the Forgotten Kingdom, follow the main forge path and head left past the Runemaker and Enhancer areas. You’ll spot two goblin guards—behind them sits the Goblin King on his throne.
Step 3: Complete all five Goblin King quests
Each quest must be completed in order. Every step increases the Gold cost and introduces rarer ore requirements.
| Quest | Requirements |
|---|---|
| Quest 1 | 5,000 Gold |
| Quest 2 | 10,000 Gold + 3 Topaz |
| Quest 3 | 15,000 Gold + 5 Diamonds |
| Quest 4 | 20,000 Gold + 5 Emeralds |
| Quest 5 | 25,000 Gold + 5 Rubies |
Step 4: Use the Goblin Cave key
After completing the fifth quest, the Goblin King rewards you with the Goblin Cave key.
Use it on the stone door positioned to the right of his throne to permanently unlock the Goblin Cave.
Enter and explore the Goblin Cave further.
Goblin Cave ores and crystal types
The Goblin Cave is unique because it spawns crystal ores that do not appear in standard mining zones. These ores greatly increase forging multipliers.
| Ore name | Rarity | Approx. sell value | Forge multiplier |
|---|---|---|---|
| Orange Crystal Ore | Epic | Medium | ~3.0× |
| Magenta Crystal Ore | Epic | Medium | ~3.1× |
| Green Crystal Ore | Epic | Medium | ~3.2× |
| Crimson Crystal Ore | Epic | Medium | ~3.3× |
| Blue Crystal Ore | Epic | Medium | ~3.4× |

| Arcane Crystal Ore | Extremely rare | Very high | ~7.5× |
The Goblin Cave is expensive to unlock but pays off quickly through superior crystal ores and long-term forging potential. Once unlocked, it becomes one of the most valuable farming locations in the game. Crystal ores dramatically increase forge multipliers, making the Goblin Cave essential if you’re aiming for top-tier weapons and armor in The Forge.
