Hello,

I have a question about the shield parry effect i see during adventuring.

Can the parry of your shield be improved by adding points the 'parry' skill?

thanks,
seems to parry on odd intervals

It is an animation specifically for ranged attacks that fail to beat your AC. It has no mechanical function other than looking 'cool' when your character deflects a ranged attacker.
