And what exactly is the demand for usuki dolls, non-gourmet but stil rare food, etc..

non gourmet food = K quest


know nothin abt usuki dolls tho

Given enough time, yes it is possible for other items too. It really depends on the shop and the number of rarities that may stock in said shop.

Is it something like how many times these common item restock b4 a r99 would came by?

Too bad I hate maths

the puzzle is so simple and I bet all these prize we get would be worthless real soon

People buy just about anything. If humans were once sold as slave labor, why wouldn't an online digital item be sold for cosmetic purposes?

No, ppl dont just buy anything, it's all depend on supply and demand.

More demand less supply the item get ridiculously expensive
More supply less demand the item rot in your shop until everyone is selling the same thing for 1np

That's strange, because my ptery's level is over 50, and sometimes his "pteri" ability doesn't show the whole 6 icons (even doing the whole math, it does between 4 and 6 icons).

Weird, I never saw inconsistent in the pet's specie ability.

It's either 6 icon at higher level or 4 icon for lower level pet or weaker abilities like kacheek smiles
