Diamonds
What diamonds are for
Diamonds are the currency that survives a run. You earn them from runs, daily quests in the Chronicle and the weekly leaderboard. Spend them at the Diamond Trader on permanent upgrades — the same catalog the game itself reads, listed here with every cost.

Skill and potion slots are the upgrades that change a run the most: a fourth damage skill or an extra potion multiplies everything else. Reroll charges let you redraw a chest item you do not want.
Mastery
Hero mastery ranks
Every run raises the mastery of the hero you played. Each rank grants a permanent bonus for that hero; you choose which of these three the rank goes into, or let the game pick.
Damage
Strengthens all skills.
Max HP
Raises maximum HP.
HP Regen
Improves healing over time.
Weekly
Weekly leaderboard and the Chronicle
Your best runs count toward the weekly leaderboard, and the top places earn diamonds when the week resets. The Hall of Fame on every floor’s plaza shows the current standings. The Chronicle holds daily quests — finish them for extra diamonds — and the beginner’s guide explains the rest of a run.
