Can you unlock artifacts similar to cash shop one?

I was looking online and it seems like some of the cash shop things give you artifacts that give the effect, but how to the others work? Like does the x2 EXP give you an artifact for it, but the one for +100CP is just like an item you use once and you get it?

I guess really my question is, can you unlock an artifact that increases the carrying capacity or are you literally stuck paying if you want the bigger inventory?

only consumables are limited to 15, everything else I believe is 99 (like ingredients, materials, etc...)

That said, if you want consumables to go up to 99 the DLC is the only way to do it now.

In the past games you could buy that upgrade through the grade shop, not anymore though :(

There are late game artifacts you can find that give +20/40/60/80% CP/SP/EXP.
But its very late in the game so more in the post story cleanup for extra bosses and such.

There is no artifact ingame that raises your consumables carry capacity, that one can only be bought as DLC.
