Mod: Item Duplicator

The mod «Item Duplicator» is needed to double any items. It works with absolutely any item, and you don't need to enable any experimental features for this.

Using the mod is simple. Take the desired item in your hand, crouch while holding Shift, and then jump; after landing you will get it in double quantity. You can repeat this as many times as you want. The dupe works even with non-stackable items, but they double one at a time.
