Can I limit the Auto-Battle decisions? & Limited items a shop can sell?

In my current project, I'm making sure the main protagonist is the only playable character in battle. Though, I want to limit the decisions available for the other Actors that use the "Auto-Battle" feature.

What I want to do, specifically, is to prevent the extra Actors from using items.

(I know it sounds weird. The reason is because in my game, items are VERY scarce)

Anyway, is there a way I can do this?

Oh and a second question:
Can I limit the amount of items a shop can sell?
Like I said above, items are scarce in my game. I have stores, but I don't want people to just save up all their money and dump it into the stores for items that are usually low on stock.

(Like is there a script or something that can do this?)

For the second request, I don't really see why that requires a script - you set exactly what items you want each shop to sell with the Shop Processing.

For the second request, I don't really see why that requires a script - you set exactly what items you want each shop to sell with the Shop Processing.

I believe he wants only a certain amount of the item the shop sells to be available, so I'd imagine a script would be required?

Yeah Darico's got the right idea (That's what I meant).
Like, say for example, you want a shop to sell an item. Let's call it "Item1"
BUT - you want the player to only have a limited access of that item from that shop.
So you'd want a script to get a Shop to only sell a limited amount of "Item1" or whatever else.

This will help you. This script can do what you're looking for in the second part of your request by limiting item stock in a shop.
