there use to be a list somewhere. How do i find the cheapest items to frag. Please and thanks.

I think it's all items with rarity 1-99, and then also items in the "Game" and "Holiday" categories. There might be some others, but I'm pretty sure at least all of those are covered.

Anything rarity 66-99 guarantees at least one crystal per frag. As do game prices like Ikumoradeekanox fruits. Subetalodge item lists are a good resource for finding cheaper ones. http://www.subetalodge.org/list_all/sort/userprice-asc/rlow/66/rhigh/99/excludeub/on

Thankyou and got my item i needed from crystal shop
