Actually, a power fist would be OK under the quote posted. "Any WEAPON attacking the Monolith". The unaumented strength of a Power FIst is two times that of it's wielder. Weapon strength, not unaugmewnted user strength.DaemonsR'us said:
So I could be difficult and state that anything that augments the strength of a model (Furious Charge....) would still work, since that modifies the user's strength, not the weapon strength.........
Oh yeah, to answer the question, I haven't seen the phrase he quotes either, Have to poke around.
