Arcane Crystal The Forge Roblox Guide, How to Farm & Location!
Arcane Crystal is one of the toughest materials to hunt in The Forge, and many players get stuck because its drop rate feels almost non-existent. Still, with the right setup and a good understanding of how the mining system works, you can boost your chances and speed up the process.
This guide breaks down what these crystals are, why players want them, and how to farm them efficiently without wasting time. Also check out our Roblox The Forge Beginner Guide for those interested and the Race Tier List.
What Are Arcane Crystal & What You Need before Farming ?
Arcane Crystal sits at the very top as the rarest ore in the entire game. It has a drop rate of 1 in 100,000, making it something players usually get from pure luck. Even though it doesn’t give any special effect, its multiplier is extremely high, and having it in your index is considered a big achievement.
To increase your odds, activate every luck buff available. Stacking these makes a huge difference over long farming sessions. List of useful buffs:
- Angel Buff: +30% Luck
- Achievement Luck: up to +40%
- Luck Potion
- Totem (optional but helpful)
- Pickaxe with Luck Bonus
With all of these active, the crystal cycle becomes noticeably faster.
Best Farming Location: Goblin Cave

Goblin Cave is the community-favorite spot because its rock respawn cycle works perfectly for crystal farming. Every time you mine inside this cave, rocks can turn into several different materials, including:
- Core
- Basalt Core
- Basalt Rock
- Crystals
The goal is to take advantage of how quickly crystals respawn here. Since you don’t need to move around much, you can keep mining in the same area and continuously trigger crystal cycles. This consistency is what makes Goblin Cave the top choice for rare ore runs.
Farming Arcane Crystal and Rainbow Crystal takes patience, but using the right buffs and sticking to the Goblin Cave routine gives you the best shot at getting them. These drops are rare for a reason, yet with enough prep, the grind becomes manageable and much more rewarding once you finally see them appear in the Forge.
