An Npc who would have stock that changes daily or stock from previous days with different pricing and could have really good deals or be a total ripoff
I'd say some of the things that the regular wandering trader trades and also some other things villagers trade and maybe like super rare vanilla things for cheaper than what players sell them for or a lot higher but you can only really buy from it not really sellHey Jack!
Cheers for the suggestion, apologies it's taken me so long to get back to you.
I know it's difficult to use the vanilla "Wandering Trader" feature due to how they are only spawned one per player, so I could definitely look into a different system that handles it.
What kind of items/blocks/etc would you be interested in seeing in a Travelling Merchant?
