What is confirmed
Bring excavated finds back to base and use a sprayer to remove dirt and dark magic.
This entry deliberately separates official description facts from player inference. Exact prices, rates and named relic tables will be added only when they can be sourced reliably.
How it fits the loop
Dig Haunted Items connects exploration, cleaning and museum display into one progression cycle. Profits feed back into shovel, sprayer and plot upgrades.
