Like the title saids this part-time job Trains your Blacksmithing skill but it's smart! it knows what rank your on o.o
Atm i'm Rank B blacksmithing at 85%.. and i hit Int ptj's yesterday and i was like... 9%(From making metal boots Normally)
i love This Ptj... it saves you alot of money!
and the thing is, the items he wants you to make is based on your Blacksmithing rank
-Aka at rank B blacksmithing on int Ptj's he'll only give you Vito crux boots and arish boots and the best part, You can keep the mats after completing the Part-time job.
Side note: you can go to your homestead while doing the Ptj and use the anvil with a Japan Ceder tree next to it for the 2%.
