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.
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.
Supercharges your resource loop: Ticks, Moments, Seconds, ores, XP, and Intelligence.
Adds movement, damage 🗡, and crit chance 🎯 for clearing Diamond Mine mobs.
Faster forging, extra Mining Speed ⛏, and a bigger Miner's Grace chance.
The two nodes every branch grows from: Diamond and Flesh multipliers you'll want maxed early.
Economy Nodes #

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.

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.
