Guys, please do not make me GM Spank.
Also, projecting a car/van is pretty far fetched. Like I said, summoning it from another dimension I would have let slide, but a car has a lot of working parts. It's like in Terminator 2 when John asks the T-800 why the T-1000 just doesn't turn into a bomb or gun to kill him. The T-800 replies that it's too many complex chemical and moving parts that he can't replicate.
There's a limit to what magic can do.
Like I don't see the absurdly powerful Ruby tracing a car. However I do see her yanking one from another dimension though. That's plausible.
I clearly state in my rules that you have to make something believable. Singing a car into existence makes me go, "WTF mate."
Also, about weaknesses, take Forest for example- I list pretty much every weakness she has in her character sheet. So has everyone else with their characters.
I'll allow it this time because it's already happened, but next time, do something plausible please. Or at least, in the words of Tim Gunn, "Make it work."
