Joko is the npc located in crimsonwood that gives u the crafting mateirals for balanced fury / crystal illbies and some out dated items .
The problem is that everytime u want to trade the badges required u can only trade once in a time and not a stack. for example i had to talk today 90 times to the npc for getting crystal shards (rng is bad only got 4 shards maybe buff that a bit too) which is very time consuming and exhausting. if u could add a possiblity to turn in a stack that would be very helpfull.
