Energy
Energy can be used to mine rocks that block your path towards completing the challenge. When your energy level reaches zero, you have failed the level and will have to start over.
Loosing energy
- Mining rocks (stronger rocks require more mining attempts and thus take more energy)
- Encountering monsters (if they manage to touch you or hit you with a long distance attack)
- Environmental damage (if the area becomes to unstable, rocks may fall down or lava may appear)
Gaining energy:
- Mining red crystals
- Trapping monsters
- Mining rocks (you sometimes randomly obtain +1 or +2 energy when mining rocks)
