Question

How does cha work (on LoA if there's any difference between servers)?

Is it:

Normal: (cha/6)+1 = monsters/pets one can have
Dires: cha/6 = dires one can have

Or:

Normal: (cha+6)/6= monsters/pets one can have
Dires: (cha+6)/8 = dires one can have

Or some other way?

Answer

Well, we really had no clue about this, so we asked GM Abularkin, who told us: "To the best of our knowledge, CHA is a core game mechanic that cannot be changed. Thus, it works on the North American servers exactly as it does on the Korean servers."
