A very important part of goldmaking in Midnight is your profession stats. Stats have a VERY Significant impact on the profit and you need to optimize them.
The impact
As an example we will look at one of my alchemy alts. I have a quality 3 rare tool and the uncommon tools on this character. Light’s Potential has a concentration value of 14g56s if I have all my tools equipped. If I unequip them all, it goes down to 12g18s. For the flask of the shattered sun the difference is 8g19s without gear and 10g61s with, almost a 20% increase. If we go to tailoring on the same character I can craft rank 1 arcanoweave bolts for 24g profit without my profession gear, If I put it all back on my average profit per craft is 405 gold, the difference completely makes or break the craft.
Which stat?
If an item can multicraft, then multicraft is ALWAYS the best stat. This is a mathematical necessity as multicraft gives you an entire item extra at minimum. This means for most professions and use cases you will want a multicraft tool and a multicraft enchant. I would in most cases suggest splurging on a rare max ilvl tool with a max quality multicraft enchant. Usually this is well worth it, even for concentration alts
Resourcefulness for some
The examples where resourcefulness is better is for items that do not stack. This means enchants, milling and prospecting and crafting profession equipment, weapons and armor. A lot of these crafts coincidentally also have some very valuable materials, which makes resourcefulness extremely good. Petrified roots, epic crystals, majestic items etc. are all very expensive and proccing a resourcefulness proc on them is a significant profit increase.
Skimp on stats you don’t need
For concentration alts in particular I think it makes a lot of sense to consider skimping on the equipment that does not have the best stats. If you have an alchemist then getting the rare version of the resourcefulness/crafting speed slot is quite low value as multicraft and even ingenuity are a LOT more valuable for you. You can save a lot of setup costs by going for uncommon versions for these slots, particularly when you don’t really need the +skill. The examples in the beginning here are for a side alt where only the tool is rare.
Make it back
As of right now a rare tailoring tool with a max quality multicraft enchant is about 20500 gold. It increases my bolt profits by 300 gold for arcanoweave and 240 gold for sunfire bolts. That means I would make it back in 40 cooldown cycles, not including the value I get for the concentration crafts I can also do.
