⭐ The XP curve
XP comes from breaking rock, uncovering stairwells and putting foes down.
Each level hands the miner a choice of three cards — perks, and from the ability level, skills.
🎖️ Level-up perks — the stat boosts
Stacks is how many times one miner can take the same card; strength is what
each stack is worth. These are personal — they never touch the team split.
🛒 Team upgrades — bought from the bank
Shared, and information-only by design: they show things on the map rather
than making one miner stronger.
✨ Skills — right click and space
Earned from the same level-up cards. A miner can hold many but equips one per
key at a time. Cooldown is in seconds; the magnitude means whatever the skill's own label says.
🦇 The foes
Health, damage per hit, walking speed, XP paid for the kill, spawn weight and the
shallowest level each can appear on. Weight 0 removes one entirely.
⚔️ Combat rules
Miner health and how it comes back, what a swing does to something alive, how
long a revive takes — and the foe budget. Set “Foes on level 1” and “Extra foes per level”
to 0 to switch combat off entirely.
