that's a very black and white situation though. that's the same as a wizard using an anti magic zone to nullify other wizard's spells. of course the fireball is going to be diffused, it's hitting an anti magic zone. it's just common sense. i'm more referring to things that are in the grey area, like when i used that example before about Storm. (yes, i understand the point is moot now for the plot in question, so let's pretend the plot isn't in the cards in this explanation.) they both can do things with the weather. it's not fair to go to Storm's mun and say "you can't do anything about the weather because it's my plot and i said so" (i'm not saying that's how it went down, but in general.)

it's much more fair to say "my character can do this, and i know your character will probably try to do something against that, want to talk about it and plot it out? make it a struggle and create obstacles and challenges that make this fun for you and myself!"

and to the anon that mentioned the 50% power cap, you're right, and it's best i think to communicate between muns on the matter of powers and what they've restricted themselves to and what they haven't.
