Right, thats cool idea with the Helmet. Being hexproof is so cool. You can basically run every map mod, without rerolling. And you're right probably with the rings, they just buy all rings and relist them for extreme prices, its easy to control the market in PoE if u have a lot of currency to invest. But those upgrades seems cool. Chaos res will be definitely useful against bosses like Chayula etc. Good luck on the market man. Hope u get some good items :)
