What if it worked similar to the Charming set, but ran off Ioun Stones equipped?
UR - Supreme (Offhand something) of the Sage, +2 AC, +1 to Damage/Healing scrolls for every Ioun Stone equipped (Max +7). Bard, Cleric, Druid, Paladin, Ranger, Wizard.
That would be a decent swap for the Shield of the Scholar for melee offhand, would be open to all scroll casters, and combos with ioun stone builds. If it's slotted as a ranged offhand then it doesn't compete and would work with anyone using a two-handed melee, but I don't know what all shook out after the recent Archer's Buckler rules reassessment. No AC bonus and it feels too niche for a UR to me.
Man... That would be a must-have UR token for me.
Heck, I'd be fine with it as an enhanced 4pt or Relic if people think it's too powerful for a UR.
