Echoes of the Deep v2.1.2 Adds New Progression Trees and Ore Vein Overhaul

Patch v2.1.2 for Echoes of the Deep: Incremental Endless Miner, published by Spellmystery, lands with a mix of quality-of-life polish and meaningful structural additions to the game's progression systems.

What changed

Quality of life

• The Forge buff counter in the top-right corner has been recoloured for better readability.
• The Vein Extraction buff now displays in the Hand of Olympus panel when active.
• All major panels — Drill, Resonance Field, five Anomaly trees, Rock tree, and the new trees listed below — now show a running total of unlocked bonuses at each panel's bottom-right corner.

Ore Vein redesign

• Ore Vein nodes have been given names and branch identities.
• Hero and Legendary nodes retain the same average power but deliver it in larger spikes on dig and claim actions.
• Nodes within the same tier now carry different Lefkadium costs.

New progression trees

• A Lefkadium Tree (located under the Rock Tree button) buffs Lefkadium and Rock income both before and after Abyssal Descend. It survives Deep Descend but not Abyssal Descend.
• A Nidrium Tree sits beneath the Lefkadium Tree and unlocks after the first Abyssal Descend.
• Post-Abyssal Descend players who reach spawn level 10 gain access to the Abyssal Lefkadium Tree and Abyssal Nidrium Tree, both offering higher income bonuses than their pre-AD counterparts. Both survive Deep Descend but not Abyssal Descend.

For players approaching or past their first Abyssal Descend, the patch substantially widens the late-game upgrade surface while giving all players a clearer at-a-glance view of what each tree actually provides.
