Legal to buy pearls with FG here? Dont know the rules on the BDO side of jsp

Idk if it's possible is it? You can't gift pearls to ppl anymore.

+1 I’m curious what I can spend my FG on

Nothing, really. The only thing you could really purchase is a guild payout, which not many people do around here. Can't gift pearls in game anymore, items are not tradeable, so it's not possible to sell items for fg.

The only other thing I've seen done is paying fg for listing an item.

Pay someone to grind for you
