I'm working on the part of the Item Maker that lets you create instances of the item specs you've created. It will cost Credits for each one made, and they'll be dropped into your backpack.

Aside from spawning them directly, you can use the item specs as Vendor NPC stock, or NPC treasure.

The thing about NPC Treasure is, there's a drop chance, so the rate can be controlled. Perhaps Vendor NPCs will have a stock remaining throttle which replenishes over time. I'm not sure yet.

But, spawning items directly doesn't have any such throttle at the moment. Perhaps it should do. Items with a high quality rating might not even be possible to spawn, for this very reason.

I'll have to decide precisely which quality ratings are allowed, and which are banned. Does anyone have any suggestions about this problem?

A way to limit how many instances you want to directly place into your backpack would be to make it cost points. It's much easier to just place them in your backpack after all, so this should be much more expensive. Possibly from Legendary onward, you cannot place the item in your bag, you can only "Raid" for that item.

When you say Vender NPCs... Do you mean I can crreate an item then stock it in the Armoury then get credits for each thing sold?
