"Split the party?" No, this plugin allows to manage the inventory and eventually if you decide to split the party it will make it easier to have a group keep their inventory, the other one starts over with nothing, then when they reunite their inventories can both combine. (For example). That said, splitting the party is already doable through native RPG Maker commands. Maybe you would want a way to manage this easily through plugin commands too?
"Do I need to purchase other tools to use this with?" No, it works alone.
