- Attribute boost
Edge on tests. Punching harder? Re-roll those 6s. Running faster? Athletics, Edge boost.
- Missile parry
There is a vast difference between catching a ball with one hand, and catching a Shuriken mid-air, hurling it back down the corridor, and doing the same for anything short of a bullet. Training can bring you so far, the Adept Power goes beyond physical limitations. E.x. Catching an arrow, slinging it back with bow-like force, bare-handed.
- Enthralling performance
There is a difference between a good roll during a concert, and sparkling during the chorus for effect. This Power is for things that mundanes physically can't do.
- Flexibility
Argument being, they're Adepts already. It's one thing to go double-jointed, and quite another to twist into a pretzel - some people can. The entire point of this power, is that it classifies you as an Adept.
- Iron lungs
This Power needs to be improved, considering the feats people have achieved IRL that can't be done, by the rules.
- Nerve strike
This Power basically allows you to punch someone in the gut, and shut them down so hard they can't even piss themselves. Still, I think that I'd instead make it a Quality, or a Martial Art of some sort instead of a Power.
- Pain relief
Bringing someone from 'I've just been punched in the face by a team of Trolls' to 'Bit by a Chihuahua' in five minutes is pretty damned supernatural. Most acupuncture specialists need more time, if nothing else.
- Rooting
Hey, look, that guy just stopped a train, with his bare hands. I have never heard of a human being pulling that off IRL. Feel free to send links to the contrary.
- Smashing blow
That's a nice monofillament chainsaw you have there. *Snap* Would be a shame if anything happened to it...
You get the picture. Most of these Powers are beyond what physicists believe is physiologically possible for the human body to accomplish. I've heard of some impressive things going on, but most of it can be summarized as Edge, having a hard-capped Attribute, or both. The rest is precisely what inspired Shadowrun's Adepts in the first place.
