Uffington actually has 3 services and 2 optional powers on his Spirit of Beasts. I completely forgot about Optional Powers, though. Let's go with Concealment and Noxious Breath. Once things get going I think we'll rely on Fear to get the Technoids running, but Noxious Breath may come in handy, as it's doubtful many of them have respirators or gas masks.
Uffington will use his first service to have the spirit use its Concealment power on the team as they make their approach. Maybe that's overkill, but the plan really revolves around us getting into position so I think it's a service well spent.
ETA: @Tec, thanks for keeping me on the ball with the spirit. I'm really new to all this wiggly finger drek.
