No No No Sheep
Thanks also from me for the answers. So its not at all linked to the sphere of the heroes - So you could play an attachment from the spirit deck to a friends tactics hero?
yes as long as you use resource from spirit hero to pay your spirit card. btw check the text on attachment , sometimes an attachment got a pre-requisite 'Attach only to a SPIRIT hero' or something like thats.
BTW for long time i play i thought i cannot put attachment on other Sphere's heroes or other players.. like im limiting myself lol
