Ultimately, this rambling, meandering story boils down to a rules question.
Okay, here was the circumstance in the session, more or less as it went down.
Setting: A PL8 campaign, set in a depressed former industrial port city.
Scene: In a park, near a bronze statue.
Opposition: Several gunmen, hired mercenaries contracted to deal with the problem, namely the PCs.
Given a mass combat scene with multiple attackers, the group's (flying-speed-)brick sought to use her 8 Strength to pick up the statue and use it as a thugplow, for an Area Attack.
Correct me if I'm wrong, but that would constitute a "Power Stunt," and incur a Fatigued condition per the Extra Effort rules on p. 20, yes?
(And oh, by the way, this is my first post on these forums, and I wasn't quite sure what terms to feed into Advanced Search beside "area strength" to get a reasonably perusable set of results.)
