Mines & Monsters Strategy, Data & Details
Enter with one primary objective
Depth progress, ore, monsters, artifacts, and quest items all compete for time and inventory. Pick one priority and treat everything else as a bonus.
- Pack food for the intended depth.
- Leave several inventory slots open.
- Bring the tools and combat gear the route needs.
Know when a good run is over
Health, stamina, food, inventory, and the clock all set the return point. Leaving with the target resource is better than losing the whole day to one more floor.
- Set a clock checkpoint before descending.
- Use food before the situation becomes desperate.
- Return when inventory or supplies stop supporting the goal.
Quick checklist
Mines & Monsters Planning Checklist
- Choose depth, ore, monster, or quest as the goal.
- Pack food and leave inventory room.
- Watch health, stamina, and time together.
- Leave after securing the target reward.
