Re: Superior Hold
Yes, multiple actions is a point of contention, but I interpret this as an NPC power, a challenge to be overcome. This type of power is an element of a Chain Golem I invented for AD&D 2e and then D&D 3.x: a hunter golem that took captives alive. This also appears to be something which a Doctor Octopus type of character might take.
The less problematic way to do this by straight RAW would be to give the hunter golem an Aspect "My Body is a Cage" and then Invoke that after an opponent has been Taken Out normally. The victim will be held (by narrative power, not by any skill) until the other PCs manage to Take Out the hunter golem or it returns home with its prize.
However, another option for this is to make it an in-scene challenge to be overcome, in which case I feel it potentially valid to give the hunter golem an extra effective action in order to make a challenge for PCs. The captured PC is going to fight the grapple; the other PCs will probably try to Take Out the hunter golem: the players still have agency.
So, if a power has to be good for PCs as well as NPCs to be considered valid, then yes, this one is problematic, but then, allowing a golem as a PC is a pretty singular GM decision.
