The Underground Miner

A mob that is peaceful, at times…. It has a trading system like the wandering trader, but will spawn deep in the caverns, and will trade things needed to survive the caves, like pickaxes, etc. 

You can buy it in 2 ways, the cheap way or the normal way (in prices). If you choose the cheap way, you have a chance to be attacked by The Miner with his stone pic axe in hand. And if you choose the smart way the first time, he won’t ever attack you again even with his bad prices.
