Chronostone Pickaxe Trim

The Chronostone Pickaxe Trim is a Calcite Caverns-themed pickaxe trim that buffs your mining run.

It grants 10% increased XP, 10% increased Ancient Energy, and 10% increased mining speed, plus a small per-block chance to earn bonus Calcite mining time while you're in the Caverns. The trim is soul-bound — once applied it cannot be removed, reapplied, or moved to another pickaxe (so the Trim Remover won't lift it), which keeps it from being passed around to game the Caverns' per-day cap.

Since Map III those bonuses and the Calcite ability are printed on the pickaxe itself, not just on the trim item, so a trimmed pick shows you exactly what it's carrying. Its mining speed also folds into the single additive mining speed pool alongside Efficiency, Momentum and your prestige bonuses.

Where to get it: an uncommon find tied to the Calcite Caverns — every block you mine there by hand carries a tiny chance to turn one up. It shows up in your trim list via /trims once you've earned one.
