So these may seem silly question but with such a lack of info in the thing called a manual and having not played any TES ganes in the past, these could be vital.

Do you do extra damage when attacking or being attacked from the side or rear?
Is there a base crit % chance?
How much more damage do Power attacks actually do?

While these questions might seem prett basic, I guess i'm used to having more stats and info available to me in the games i play.

Any help would be appreciated.
