Amulet of Folkvagnr: I'd just reprint Stu-Pendous Pendant. If not, I'd make this not strictly better than Stu-Pendous Pendant, something like: +2 STR/+4 DEX, +4 STR/+2 DEX, +3 STR/+2 DEX/+1 CON
Earcuff of the Cabal: It's fine if not, but should Monks be allowed on this, as they can use Mystic Staves?
Nightsahde's Grim Gloves: This token just feels troubled. Now I think it might be too weak to be desirable. Maybe this could bypass crit immunity on the attack it is used for as well?
Picc's Grindstone: Last comment I'll make on this: I don't like slotless, no drawback, good for everyone power creep like this. I won't buy this, or tokens like this. (I got rid of my Goblet of Toasting for the same reasons). I think it's a slightly different story for transmuted tokens, at least they do the community good of increasing demand for trade goods.
Shield Maiden Bracers: Rangers can use neither two handed melee weapons nor shields, and shouldn't be able to use this token.
Monks, Rogues, and Wizards who can't use shields should probably also be excluded.
Thor's Mug of Melee: There is no real reason to prevent Wizard's from using this token, they can use the rare +2 damage offhand melee mug, and the rare +2 to hit offhand melee horn, and the Ultra Rare offhand Orb of Might.
I guess there is some thematic reason of Thor having enmity with Loki who is more of a caster. If that's the reason then fine.
