The Main level perk Scout I/II/III is described as (for Rank I)
Slightly increases the sight distance of Fast Travel and also the chances of Evading by 10%.
I believe the Evading part refers to avoiding fast travel events ( i.e. attack etc., if the player wishes to avoid them) and not physically evading like to parry. The higher the rank, the higher the % chance to evade.
The first part relating to Sight Distance I don’t understand what that is or how it works if anyone could explain please.
