@Will_2_Power:
This is a good tip, as it will add more stats as well as make the affixing formula simpler.
However, the point was to be cheap, and I suspect Arks Fever on units is not cheap. I currently cannot check the prices for you though.
If it is too expensive for you, it may be worth it to wait a couple days, since PSO2 day (Aug. 2) is soon. More units with Arks Fever will be added to the market, and prices should come down.
