The Motherlode
The (image)engineer vilager is located here
Mine the motherlode to get ore, after a certain amount of ore gained you can destroy a layer and gain an Opal,
then the efficiency required to mine the motherlode increases and so is the ore amount required.
You are capped at 5 layers broken per day, which is also shared with the other caverns related to skilling.
The Dawg Den
Fight hounds, each hound kill gives a score, hounds that stay alive for too long start to generate fear.
once the fear bar fills up you lose.
You can get Opals based on your highest score.
The Score Multiplier can be increased by charging the amplifiers by clicking on them, to reset you need to hold down.
Amplifiers are unlocked through Kaipu, Engineer of Schematics.
