Selling full stack of cards to any vendor should yield the described item.

You should also be able to sell multiple sets of cards at onсe.
And "trade divination cards" option should be removed as redundant.

You know what? Yeah, that makes sense.

+1

Maybe still have a specific div card NPC, but change the interaction to something similar as you described, to keep with the lore. Maybe multiple slots to put cards in, like a hand of cards

I would like to see this as well; of late it's come up because I keep picking up the card from Niko, and having to individually trade divination cards to convert each one into a stack of 10 alteration orbs is a nuisance, albeit a mild one. It'd be much nicer if I could just mass vendor them to get the orbs.

I understand that since the div cards are made as a supporter thing, ya can't just change the sulphite to drop the 10 alterations directly.

Being able to vendor multiple sets at once sounds amazing, +1

I have definitely control clicked lilly roth and vendored a stack of cards on accident before

navali was a seer which used cards as a method of divination

suddenly she gets gutted and our pirate queen lilly roth learns divination out of the blue lol
what is the lore justification for that? did she also "got along" with tasuni when tarky wasn't looking?

it would be much better to create a "table" just like a trade window with the size of our inventory which we can put full stacks and it returns the items in a single click
obviously you only know the rolls or whatever after confirming the transformation
