Game mechanics questions

[Mini Nephthys]

I feel really foolish for having to ask this, but...

1.  Does the chapter's affinity actually affect anything?
2.  In some chapters my mounted units have a -2 to their movement.  Why is that?

[Areth]

Not sure about the first question, but the movement penalty to mounted units only happens on "indoor" chapters.

I believe the chapter's affinity gives a small boost to hit and dodge of any unit with a matching affinity (both ally and enemy, hence why they actually gave generic enemy units affinities now).

+5 Hit and Dodge as far as the affinity thing goes.

Thank you!
