I still feel confused, including because there is not just ‘Shield’. There are things like ‘Recharge’, Maximum (which is an absolute value), ‘Recharge Delay’.
I’ve provided some examples…
For Miko: Will I be able to use the Positive attributes (Health Regen), even though he doesn’t have a shield to recharge? Please assume I’ve not equipped a shield through other gear.
For Orendi: Can I equip this to gain the Shield Recharge and Skill damage attributes, even though she doesn’t have anything to reload?
Hopefully that’s more clear since the info above isn’t broken down enough to really help me understand how those play together - assuming I’m talking about just a single item at a time.
