Move Creation Workshop

[Trixie]

Hearing the shot would give him the queue to activate the move

Technically, no. Bullets travel at about the speed of sound, sometimes a bit slower, sometimes quite a lot faster. That's why he'd need to be watching either with his own eyes, or by using ES. And he'd probably need to be focusing on the gun (or have foresight) to know the bullet trajectory.

I mean, now we're entering semantics here. He's obviously going to have to specify in the move that he's focusing. Speed of Sound brings more real world stuff into Omniphysics. It doesn't apply directly here. Yes, a rifle round is going to beat the sound to your target. It also depends on how close you are to the gun when it's fired. 

I agree if he writes the move as concentrating or gets ES he can do this. 

My general preference for moves is to always clarify. If someone describes themself doing something that wouldn't normally be possible, I'd like a clarification on how. Just something small such as "the rock moves as fast as he needs it to". If a move won't work every time, it should generally be specified. Not specifying that is actually detrimental to the user, since having a low success rate or having it only work in very specific conditions can allow for either a boost in power or for fewer or more negligible drawbacks being required.

I agree in the context of making a move stronger or weaker. It's a given that no move is going to block anything 100% of the time. That's why fights are graded and read. If you're bouncing around dodging everything and your opponent can't hit you no matter what, that's just poor writing. I look at a blocking move as a tool to be used if I can and reasonably. Right?
