I can't find them in currencies and can't use them for ruffie raffle... thank you in advance!

so the name on the bath house is outdated and very confusing for newer players, but the raffle tickets earned from the bath house were changed (quite a while ago) and are actually now called Forum Tickets. they can be used to buy things in the forum shop!

editing to add that you can earn forum points randomly by posting on the forums too!

I see, thanks!
