I’m wondering if they are considered as a part of your servant and thus work with her skills that require them.
Do they get extra shield from Contractual Obligations or Protect Your Assets?
Do their kills add a stack to Valet or trigger Keep Your Chin Up?
Does their damage trigger Excellent Shot, Madam?
The extra shield sounds hard to test but the other two don’t really. unfortuantely I dont have an extra controller so i cant test myself.
