I'm playing AC Valhalla last 2 weeks.
For now I'm doing some quests from Chapter 1 (just completed Soma quest).
But all these days I was paying attention to increasing skills of my character by side quests.
For now it is has 276 strength points.
And is was quite easy to play vs AI enemies with much lower level.
BUT, since I've passed several Freya Mastery Chellanges - the world has changed and minimum enemies level become 316!!!
So, all these quests are marked with RED Color, because my level is lower then required. For Chaper 1!!!!
I think it is not fair - I've passed, but they were significantly improved!
