In the two-handed tree, there are perks called Sweep and Warmaster.
- Description of Sweep: sideways power attacks with two-handed weapons hit all targets in front of you.
- Description of Warmaster: backwards power attacks have a 25% chance to paralyze the target.
So, how do I perform sideways and backwards power attacks? How do I know I performed any of those two (animation, angle of swing or something else)?
