OK, had these for a while, but apparently forgot to post them here on the website. I have uploaded the following Unearthed Arcana File Sets.
III.C.2 Rings
III.D.2 Rods, Staves, Wands
You can get them from the file section.
Still working on III.E.x Miscellaneous Magic (there is a ton of items, not as bad as DMG, but close). I will post them as time permits finishing them.
