Miner's Bad Temper

You get angry quite easily when provoked (insulted or hit), you can roll Will & Control, or the GM can make you do it, and if you fail the roll, you are furious, and your hits are devastating.
Once a day, you get to add +4 to a single damage roll of your choosing.
Plus, you get a +2 modifier to all your damage rolls when you use mining equipment (pickaxes and shovels), as your weapon of choice. For you, they count as a heavy weapon.
