Kotryna, you don't need an Item code. Here is how I download items and put them on FH, it should be simple to follow.
1) Ensure you have Winrar. If you don't, then download it, it should be easy to find and it has a free trial that even when it expires, you can still use it for some reason.
2) Download any items pack you wish. I reccomend Legendary Items Pack;

Step 1: Place the CFG file into the FeralHeart folder. Once it asks, "Replace", ensure you replace the current CFG with that one.
Step 2: Extract all item files into FeralHeart>Media>Items.
I hope this helps. If it doesn't work I don't know what to say.
