Hard Modifiers
Optional difficulty flags that change core game rules. Can be combined.
Hard Modifiers restrict how you're allowed to play rather than making individual blocks tougher — they remove or devalue an entire income source or system, then leave the rest of the run intact. A player can only enable one Hard Modifier at a time, as they are essentially distinct "challenge modes" layering on the existing game content.
Three of the six modifiers below target income directly (ONLYCOAL,
COALISWORTHLESS, NOBONUSCASH), one removes the chest/passive
system entirely (NOCHESTS), one removes a key shop upgrade path
(NOTIMEUPGRADES), and one restricts which biome can spawn at all
(ONLYCLAY).
| 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. | Filling your coal quota earns you nothing, but you still have to do it. |
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. | You're stuck with the starting duration and cannot buy Add More Time upgrades. |
ONLYCLAY | Only clay-biome blocks spawn, regardless of depth. | Mine is locked to the shallowest biome. HP/yield values remain at clay scale throughout. |
