The new rings can also use the CM Enchant Scroll. In order to get the +1 crit bonus, you'll need to have both Cold Thorn and Cold Dagger if you're an STR character and Cold Witch and Cold Desire if you are an INT character. The belts that are Lvl 85 require a material from Habitant (Habitant Essence?), 2 Smooth Shards (current smooths we have now, not carved), Paradise Orbs, and Godly Iron Ore. This information comes from watching Afk's livestream. The rings will use a material from one of the Chapter 2 Ep 3 bosses.
Fun fact: the 2 variants of STR and INT rings have the same stats, different names it appears. Cold Thorn and Cold Dagger have same stats, different names but both are required to get the +1 crit bonus. Same applies to Cold Witch and Desire.
