Here is a few examples i feel could be applied.
Diamond cutter (shared or independent tool)
Description : A tool used to turn uncut diamonds into "Fine", "excellent ", " Brilliant " Diamonds. These diamonds can be used as currency once finished refining
Cool down : 4 hours
Output: Create different grade diamonds based on diamond cutting skill
Sand melter ( if recoded possibly) Ore melter
Description : A tool used to melt down rare metals, pure gold, or common ores. Can maybe make coins or armor or even something new.
Cooldown : 1 hour
Output: Depending on what you put in the melter will depend on what you get. Pure gold can give a gold coin or even more if skill if high enough. If rare metals are put in the melter they can put out rings, necklaces , nice jewlery ect. If Common ores are put in it can put out usable metals that can be used to reinforce a lumber barrier. Or even something else .What you get will vary based on skill.
Mist of the Shard (Tool for Lonsadaleite shards )
Description: A tool used to turn Lonsadaleite shards into powerful potions or Orbs that contain a token for your creature
Cool down 1 hour
output: When putting Lonsadaleite shards in this tools it can create an orb that holds random amounts of Vital energy when skill is high enough. Some times it can create a random token that can be added to your creature .
