You mean like, if you say the caster's name backwards, the magic stops?

[ The guy isn't necessarily wrong about magic having rules - and isn't wrong about Tim needing help - but it's hard to quantify the rules when they keep changing. ]

It depends on the individual's magic, power source, external or internal, demonic or otherwise, et cetera et cetera... you wouldn't happen to have a mirror on you? I can stitch myself up.
