First of all, I really like the changes. There are now around twice as many URs than I was originally planning to pick up from the new set.
With that said, there are a few specific tokens which stand out for me.
Charm of the Brewmaster - I like the theme, but mechanically this would need a boost for players to want to include it in builds. Maybe giving it a thematic second ability like every potion you drink granting you +2 STR wouldn't be overpowered since it costs a slot to equip?
Cranston's Helpful Hat - This is my main reason for posting on the thread. I really, really think that the current ability needs changing. Since Sniper Spectacles exist, the ability currently on Cranston's is terrifyingly powerful. Even without looking at the rest of the token pool and without thinking about any future tokens, if you own the spectacles then the hat will effectively be a single-slot head token which is equippable by all classes and grants +5 to hit with all ranged attacks. Can this be changed to either a will save bonus, being able to see invisible enemies or (unpopular opinion due to the small number of UR eye tokens and existence of Lenses of the Fae) the original ability of being able to hit incorporeal enemies?
Earcuff of Orbits - Again, I am very happy to see this in the same year as Platinum Nugget and Elfstone Shard. I'm aware that reprinting it now may possibly make it harder to find in several years time, but that's already a current problem right now and I'll be very surprised if we don't see any new slot enhancing tokens as alternatives at any point in the next several years.
Lucky Cloak - I'd be fine with this being either boots or back. Players who own Boots of the Four Winds and Pharacus' Greater Cloak of Destiny will very likely not equip this regardless of which slot it ends up in, and players who don't own them will likely have the option of equipping it in either slot if they need a large save bonus (especially with the recent reprint of Charm of Brooching).
Psyferre's Spectacles - I like this token, mostly because it's unique and will offer players some very interesting choices for Figurines and Scrolls if they equip it. Plus, if CHA gets used more in the coming years it's only going to get more useful.
Ring of Sacrifice - I'm not sure how much this ability will actually get used if it requires a standard action, I'd prefer to see it as a free action which deals less damage.
