What should I continue from this point?

Another question. When you have all 50 cross-class skills, and you only wearing white gears (HQ also) without meld, it is possible to craft class gears

Yes - easily - look up the "hasty method" of crafting.

You'll be doing something like this:

CZ - IQ - SH2 - Hasty x5 - SH2 - Hasty x2 - Mend2 - Hasty x2 - SH2 - Hasty - Ing 2 - Basic Touch - GS - Byregot's - CS2 - CS2

It's all about dragging the craft put as long as possible to get as many IQ stacks as possible before your GS - Ing 2 - Byregot's Finisher.

Use Tricks of the Trade on Every "Good" and re-apply SH as needed, the above is just a rough idea, as the hasty method is situational.

Re-apply CZ if you think your craft will last another 10+ steps.

Can add Inno before Byregot's if you have spare CP.
