The only modification is that now you can see the mouth animations of the helmet. And that's all. No other changes were made to the stats of the helmet, it is the same one but now you can see the mouth animations.

How to install:

Download the zzz_opened_italian_bascinet.mcpack or zzz_opened_italian_bascinet.mcworld file from the Downloads/Add-Ons folder of your Kingdom Come Deliverance installation.

Open the Add-Ons folder and extract the file.

You will now have to install it using the Kingdom Come Deliverance launcher.
