🌱 Pure Diamond Upgrade Tree

Pure Diamond Upgrade Tree

A permanent skill tree bought entirely with Pure Diamonds. Its nodes branch out across your economy, combat, and mining, and once earned, they stick with you through every reset.

Overview #

The Upgrade Tree is opened from the Upgrades NPC in the Diamond Mine and is spent purely in Pure Diamonds, the scarce currency you refine from ordinary diamonds at the Diamond Forge. Every purchase is permanent: nodes are never lost to any reset, so the tree is one of the most important long-term investments in the game.

It unlocks once you have ever reached Time Leap 12 (Diamond Breaker), the same tier that opens the Diamond Mine. Because that best-ever tier only ever ratchets upward, the tree stays available even after an Era reset temporarily lowers your current tier.

🔑
Nodes unlock in sequence: buying one opens the next along its branch. Costs are in whole Pure Diamonds and rise as you invest, so plan which branch to push first.

The Four Branches #

From two shared root nodes the tree splits into four directions. Each branch deepens as you invest, gating its stronger nodes behind the earlier ones.

Economy

Supercharges your resource loop: Ticks, Moments, Seconds, ores, XP, and Intelligence.

Combat

Adds movement, damage 🗡, and crit chance 🎯 for clearing Diamond Mine mobs.

Mining

Faster forging, extra Mining Speed ⛏, and a bigger Miner's Grace chance.

🔥 Roots

The two nodes every branch grows from: Diamond and Flesh multipliers you'll want maxed early.

Economy Nodes #

The largest branch. These nodes feed your entire resource chain, from the root diamond multipliers all the way up to Temporal Power and Intelligence.

💡
Crimson Infinity is the one uncapped node in the whole tree, where each level costs one more Pure Diamond than the last and stacks a fresh ×1.1 onto your XP gain forever. It's the classic long-term Pure Diamond sink.

Combat & Mining Nodes #

Two shorter branches. The combat line makes short work of Diamond Mine mobs, while the mining line speeds up the Diamond Forge and your own digging.

The Deep Crucible and Blazing Forge nodes pay for themselves fast: a second forge slot plus faster forging means more Pure Diamonds per hour to spend on the rest of the tree.

Resets & Tips #

The Upgrade Tree is one of the most reset-proof things you own. Once a node is bought, it is kept through every reset: the Seconds reset, the Chrono Dust reset, a Time Leap, the Intelligence Generator, and even an Era reset. Nothing in the tree is ever refunded or wiped. Like your pickaxes, armor, and other gear, these upgrades are permanent.

📌
The tree gates on your best-ever Time Leap tier, not your current one. Choosing or changing an Alignment triggers an Era reset that lowers your current tier, but your best-ever tier never drops, so the tree stays open and every node stays bought.
Push the forge first
Deep Crucible then Blazing Forge multiply your Pure Diamond income, which funds everything else.
Max the roots early
Crystal Bounty's ×2-per-level Diamond fortune compounds into faster refining.
Save for Crimson Infinity late
Once the one-time nodes are bought, dump spare Pure Diamonds into its uncapped XP stack.
