Hexa gems, heart, talisman and 3-set raven ss are from the ET orange quest iirc. You still have to do that after using a voucher. (unless they also changed that!)
ss primers always display as number 8, but they can be applied to an number, they are used to increase stats on ss in addition to fuse.
Use naryu silver to buy dawnrift weapon chests untill you get one with 7 or 8 gem slots, it is 10 naryu siler at a merchant in mushins tower. Also bale weapon doesn't really exist anymore.
But I don't really know about the other things.
