This is just a thought but I think that the master crafting recipes should require the Luminary tools for the respective crafts!!! This would give some purpose to the tools, as well as people would need to to do the various level of crafts, so would possibly help boost the economy. Also would give purpose to the crafters to specialize in something other then just spamming to 50 and being able to cripple the market.
Maybe as well Only useable from the workshop stations that are supposed to be added to free company housing!!!
