The Diamond Mine #
The Diamond Mine is a huge geode region you travel down to, not a separate world, just a deeper area of the same continuous world. It unlocks at Time Leap 12 (Diamond Breaker), which itself requires reaching the Stone Age. It's packed with custom monsters, the tools of the diamond economy, and the deep Pure Diamond upgrade tree.
Unlike the earlier mines, the Diamond Mine is dangerous. The ore is guarded by hostile mobs, so mining here doubles as a combat zone. If the monsters are too tough, build up your Strength and armor first; some of them carry valuable loot when slain.
Break diamond ore for Diamonds, the raw material behind everything down here.
Purify diamonds into scarce Pure Diamonds at the Diamond Forge.
Buy diamond gear, artifacts, drills, and the permanent upgrade tree.
Getting In & Meeting Korrin #
To reach the Diamond Mine you need Time Leap 12 (Diamond Breaker), which is gated behind the Stone Age. Once you're in, the first Timelord you'll meet is Overseer Korrin, who runs the whole operation.
Iron gear can't scratch these gemstones, so Korrin sells you your first Diamond Pickaxe to get you started. From there he points you toward the Diamond Forge to begin purifying diamonds, and warns you about the monsters lurking deeper in the mine.
Mining Diamonds #
Mining works the same as it does with the first three ores: hold a Diamond Pickaxe, left-click the ore, and drain its hidden health with your Mining Speed ⛏. When a block breaks it banks Diamonds into your balance and regrows after a short cooldown.
| Ore form | Yield |
|---|---|
| Diamond Fragment | ×1 |
| Diamond Block | ×5 |
| Compressed Diamond Block | ×25 |
The Miner's Grace passive can upgrade a block to a richer tier as you mine, turning a Fragment into a Block (×5) or a Compressed Block (×25), and every ore break in the world still has a chance to drop Chronite. On top of that, diamond-tier breaks are the only place you can naturally find the Diamond Chip artifact, which multiplies your Diamond fortune.
What Your Diamonds Boost #
Beyond being refined, your current Diamond balance can passively multiply other resources, but only after you buy the matching nodes in the Pure Diamond upgrade tree. Until then, diamonds just pile up for the Forge.
| Boosts | Unlocked by |
|---|---|
| Ticks & Moments | Origin Booster node |
| Seconds | Molten Essence node |
| Strength | Molten Essence node |
Because these scale with your live balance, there's real value in letting diamonds accumulate rather than dumping every one into the Forge. The bigger your stockpile, the bigger the boost.
