Babble has a lot to say about miner bounties, unless you remember to ask him for the short version. In his defense, there is a lot to say, but perhaps not quite as much as he would like.
Miner bounties are unlocked by reaching milestone 1 Miner, and then talking to Babble in Goblin Well. You can collect miner bounties from the miner bounty boards, which are located throughout the Mine of Mantuban. All these miner bounty boards carry the same bounties.
There are three kinds of miner bounties:
Mine only
- Mine ore to order. Break stone as stated. As simple as a bounty can get.
Blaze mining
- Weaken a rich ore seam or stone by setting a fire next to it, and then rapidly cooling the ore seam or stone at the right moment using a bucket of water.
- Once weakened, the rich ore seam or stone can be mined, giving extra items as a reward.
Rubblebug hunt
- Rubblebugs like to hide in their favorite ore or stone. To catch one, first you must mine the correct ore or stone until the rubblebug pops out. Then you chase it down and hit it with your pickaxe.
