You were born deep underground and have an affinity for caverns, crystals, and burrowing creatures. Your bonded object is made of a mineral or crystal that's meaningful to you. You gain the earth trait. Once per day, you can turn a fist-sized stone into a non-magical object of light Bulk or smaller as a 3-action activity. The object must be common with a level no higher than half your level, and it can't have intricate moving parts. This ability can't be used to replicate a specific object (for example, the key to a specific lock) unless you've interacted with that object before. Objects created this way crumble to dust after 24 hours.
