Modifier Effect Strategy Note
NOCHESTS No chests spawn in the mine. Prevents all passive upgrades and equipment scroll rewards. Removes the passive system entirely. Very difficult without chest upgrades.
ONLYCOAL Only coal ore blocks spawn in the mine (all other ore types are replaced). All income comes from coal ($1/unit). Combine with mining speed passives from other sources if possible.
COALISWORTHLESS Coal ore sells for $0. Mine only non-coal ores. Coal blocks still exist but yield no income.
NOBONUSCASH Bonus cash rewards (e.g. end-of-day bonuses) are disabled. All income must come from ore sales.
NOTIMEUPGRADES Time-based upgrades are disabled. Exact effect depends on which upgrades are time-gated — data pending.
ONLYCLAY Only clay-biome blocks spawn, regardless of depth. Mine is locked to the shallowest biome. HP values remain at clay scale throughout.
