Druid wolf form faction explanation

[Boilon]

Can someone give me a run down how exactly this works as a game mechanic? I am leveling my druid a bit more and been using it for certain things like being able to sell to merchants i could not before (oggok when killing guards). But, how does the faction modifier work? is it a flat + (number here) to my faction? What if I kill mobs while I am in my wolf form, does this matter compared to not being in my wolf form?

I haven't played a bard or an enchanter so I don't know much about faction modifiers other than sneak.

Just wondering because the oggok guards used to be apprehensive to me but now im at the bottom of faction and both wolf form and non wolf form is scowling. So if anyone is able to give me a run down in general how this works that would be great!
