Undying Miner

You read the card’s runes and a revenant manifestation materializes, pickaxe gripped in hands that no longer feel fatigue or pain. It descends into your mine shafts, its lantern’s glow illuminating the way.

You nod in satisfaction. The undying miner reduces the dark energy drain across the entire plot. Every worker costs less to sustain, and your undead manifestations match its tireless pace.

Deep in the earth, its pickaxe extracts rich veins of iron ore. Traces of raw aura cling to the excavated stone. During its ceaseless work, it occasionally uncovers buried curiosities.

Hours pass. It continues downward, accumulating ore and aura, and your coffers grow.
