My thoughts on this round:
Io's Crossbow
Mechanically and Power Wise, I think you could include Monk on this bow (Monks are on almost all crossbows in tokendb), or possibly even "All except Cleric" like the Stunning Light Crossbow.
Cloak of Angels
This is pretty swingy on a roll of a die - you either end up dead or at full. I think I preferred the Craven Cloak which is less swingy and probably similar power. I have no particular complaints though if this is the direction it goes - it's basically a legendary Butterfly Cloak
Divine Reach Gloves
These can be a flat +3 to ranged damage. See Blessed Tempest Gloves (
tokendb.com/token/blessed-tempest-gloves/
)
Ring of the Sacred Circle
The high DR for Darkrift is possibly going to be a problem, as there will be a lot of builds with -20 darkrift, but you won't be able to always assume -20 darkriftn damage. It also unfortunately may not stack with the greaves if the player has a Topaz Trillant, as you'd cap out with just the 2 tokens.
A different suggestion: you could get most of the power of the different rings by making this +2 all attributes. Written out in actual benefits, the end product would be: +1 all saves, +5 hp, +1 melee hit and damage, +1 ranged hit, +1 AC, and in some cases a second FoP. It's simple, follows the theme of the Arcanum Shirt, and doesn't end up with DR stacking issues. It would also make designing the Arcanum set bonus easier, as the components would be fairly predictable and uniform.
Arcanum Greaves
Why not make this just like the Barbarian Character card for clarity and uniformity? -2 Damage, excluding push and eldrich.
Bead of Divine Choice
This is a duplicate of the Bead of Asgard (
