No? Then perhaps you'd care to explain why by Canon you may have an Adept Ghouled Night Ones with Satyr Legs of the Magician's Path with the Movement Metamagic?

Besides, it is the GM's right to do whatever he wants.

I'd envision the painting of tunnels would itself be a geas on some sort of Selective Astral Gateway power.

It's never just magic. It just follows it's own rules. Rules that make no sense from a "normal" perspective.

Thanks, heh. I applied it to my own speed freak Adept. Could also steal from Speedy Gonzalez if the character is from Aztlan.

By Canon, I meant specifically the rules for PC movement and how the Speed Freak is beyond the intended scope of those rules, and not whether or not the Speed Freak is a valid character. I apologize for the confusion, and hope that it is a bit clearer.

You'd only need a few hundred or few thousand pounds of thrust to get something as unaerodynamic as a human to 1000kph (less than mach 1) at sea level (assuming no drag reduction thanks to magic).

The force exerted on concrete or pavement would not be damaging. A few hundred horsepower going through the wheels of a sportscar or semi pulling away from a stoplight would exert more stress on the ground.

However, that much shearing force on sod, sand, or other non-paved surfaces might generate quite a rooster tail of dust. Meep, meep indeed.

On second thought, the magic that accelerates the person from 30kph to 1000kph might be supplying the drag-fighting force, and thus all the thrust will NOT be transmitted through the shoes of the speedster, and thus any ground would be safe. Instead of traceless walk, perhaps you should consider some water walking spell and review "Dash's" performance in the Incredibles.

Which, even by that definition, makes it just magic. Like you said, it follows its own rules. Physics have next to nothing to do with it.

You get +2 to the power for a charging attack.

After thinking about this question, I'm going with my earlier second thought:

"On second thought, the magic that accelerates the person from 30kph to 1000kph might be supplying the drag-fighting force, and thus all the thrust will NOT be transmitted through the shoes of the speedster, and thus any ground would be safe.

This would prevent the shoes from being shredded. After all, it's the magic moving the person, not 300-horsepower legs and feet.

I think it would be a matter of perception and interpretation.

One person might view it as the Flash, another like the jogging with the distance just melting away, a third might view it as a single step between two places, and a fourth might invision it a la the full body astral teleport.

The capabilities would be the same, the effect is the same, and it follows the same exact rules gamewise for each interpretation. It's just the "fluff" is different.

Then again, I'm a proponent of the UMT.
