Hello! I am making a single server with seperate worlds for minigames, survivl, factions, ect... And I want players to (for example) buy an item from the shop (lets say it's 20 obsidian for Factions), how would the system give the player the item SPECIFICLY FOR FACTIONS? Is there a command to it or is it a plugin? Thank you for your help! PS: I do already have a plugin that seperates world inventories.
