Boots of the Sweetwoods
If feel like there should be a boots UR this year, I would much prefer something only arguably broken rather than obviously broken, like Boots of Soaring: Potion of Leaping Attack language 1/room. As this is the transmute, change the transmute to Stu-pendous, and just print Sweetwoods in 2022 as it's *not* necessary to have everything right now.
As neck slot, still would push out until 2022 because I have some patience for tokens, including tokens I would play a lot with. If hunting around for another slot, waist might be one of the few places for something so massive in terms of bonuses. Legs would work, except it should be obvious what will happen if moved to legs.
Cranston's Helpful Hat
Let's say a head slot item gave +3 damage to whatever Ranged means. That's something I'd run in builds, keeping in mind that I can easily put URs or better in every slot. Now, I probably wouldn't wizard this until it was clear what spells were affected by it, but it might even wizard over Crown of Expertise or whatever. That's with zero other ability.
Let's suppose a second eye slot isn't better than a head slot, so there's a reason to give another ability. In character for head would be something like +2 Will saves. There are times I'm tempted to run a rare in the head slot just for Will saves, though Charm slots are so cheap [sic] these days that probably do Charming Crown instead.
If want to get more helpful and arguably broken, Cranston's Lucky Hat as part of Lucky set with +2 saves, but I'm sure that's gilding the lily a bit much and distracting from the honor. Continuing to muse on how to make more OP URs that at least try to pretend not to be, Cranston's Helpful Hat: +1 Ioun Stone slot, +1 Eyes slot, that's it, just a free Platinum upgrade ... so to speak.
Ring of Sacrifice
I would push this a year (at least). What do clerics and fighters have in common that could be pushed in the Year of C/F/W? Armor. What makes clerics sad and maybe a fighter or two? Straining for Thor. Maybe it's ludicrous to propose Mutable Armor: AC +6, As Any Set w/ Armor, +4 Dex, Cleric/Fighters. So, essentially +8 AC, more Thor-y, don't lose any set bonus for a set that includes armor so you can still get your Redoubt or Templar or Lucky or whatever bonus.
