guess what this is?

2 extra spaces isn't good enough , they should revvamp it sinse its such a rare drop , maybe 12-14 Slots?

I don't think they need to change it one bit. For starters they only just fit those extra 2 slots into the UI. Secondly I love items that give a little bonus but are hard as hell to get, overcoming the challenge is half the fun. I hope they add more of these kinds of items.
