This is not clear in my edition of the Rules: may a Hero equip an Attachement Card not belonging to his/her own sphere of Influence but which has been activated by a different Hero of the Attachement Card's same Influence….that is , may a Hero "borrow" an Attachement Card from a different Hero who has activativated that same Card by legally spending resources, as it were, in favour of the former Hero who could not activate that item because of un-corresponding Influence? Thus, for instance, a ""Spirit" Hero could equip an Armour card just being activated by a "Tactics" Hero who gives the item to the "Spirit" Hero who could not spend Resources over that item. I'm playing according to a "no borrowing" rule, otherwise any Hero could just as well directly spend his/her own Resources over any Attachements, I'm still a little doubtful, anyway…Thanks for any advice.
