I'm probably not going to do this. It doesn't really add much. Just some sorta hidden abilities. There isn't much info on the mod, and I'm not entirely sure how a player is supposed to discover the niche items. They didn't even bother providing tooltips to the items. I mean I had to read code to see what the things even were. Like wearing the skeleton helmet and it gives a crit on jump attack with the bow ... how is a player supposed to even know this exists?
