I didn't use novel info. The avatar moves in accordance to how the person moves. That means blocking or dodging an attack means actually blocking or dodging an attack. That's all there is to it. There may or may not be blocking skills, but you don't even need those if you can do it manually.

Also, you are severely mistaken if you think dodging an attack in real life (which is the whole point of the NERV gear thing - full motion capture) and dodging it in TERA are the same thing.
