A character spends 4 PP on Environemnt: Extreme Cold 2, 60 ft radius. Until someone manages to nullify that Environment effect, should that character also be allowed to have Favored Environment: Extreme Cold?
Timing: It's 90 degrees out and the character moves more than 60 ft into a place they haven't been anywhere near before and then punches the villain. Is the environment considered Extreme Cold as soon as they arrive or do they need to spend a round there before their power catches up with them? (just timing here, not special effects. IOW, does the sustained power "activate" immediately on arrival before the attack action to punch the villain?)
