Miner

You’ve spent a great deal of time underground and have learned how to survive and fight in a mine. You gain the following benefits:

Increase your Strength or Constitution score by 1, to a maximum of 20.

You gain darkvision out to a range of 30 feet. If you already have darkvision, its range increases by 30 feet.

While you are wielding a warpick, you have a burrowing speed of 5 feet.

When you hit a creature with a warpick on your turn and are also wielding a hammer, you can use a bonus action on the same turn to hammer the pick into the creature. If you do, the creature takes additional piercing damage equal to 1d8 + your Strength modifier.
