IIRC multiply attack with the weapon eats extra fatique equal to number attack times melee fatique.

Unless it's changed in Dom3, this is completely incorrect. Units gain their full encumbrance worth of fatigue for every complete set of attacks they make. The quickness spell allows an extra set of attacks, which cause another amount of fatigue equal to the encumbrance of the unit. Having multiple weapons, or weapons that have multiple attacks has no effect on fatigue.
