Perception

[Rialon]

You have become better at perception!
The Juju zombie dodges your claw.
...
A hungry ghoul dodges your punch.
You learn from your mistakes, and your perception skill improves.
A hungry ghoul parries your punch.

It is supposed to be learn from your mistakes in first case, no? And not sure about second case

[Sirrion]

Success of your perception doesn't mean 100% failure of victim's dodge. Their agility can be more superior than your perception.
Same with failure of perception, they still can fail dodge in this case.
