Visitor Armor -- How should I upgrade it?

You mean +10? :f6:

We have a glitched fame quest where the quest won't complete so we get max. 128 coins a day. I'll find out in ten days if I can scroll >17 times.

I hate the ugly orange hue of the dex suit though; should I scroll str first? (I'll prolly scroll str 8 times cept for shoes)

10 cells to make it turn from bing to visitor suit. 12 cells on every piece of equip evenly before you can focus your cells on 1 single piece.
It will end up looking like the stat you have the most of.
