Charisma and personality are detrimental to each other. They go hand in hand because the more charisma you have the easier it is to charm an animal without using magic spells. You could also have an easier time charming monsters of higher levels than you with more charisma.

Try using one of the perfumes on yourself with a maxed charisma level and then go monster charming, you could make armies in seconds. Of course with higher personality also, you can charm multiple monsters at once in the higher levels of the skill tree.

Charisma is totally important to monster armies.

INT is mostly for learning skills and spells it seems. Though it does not help you directly in combat, it helps give you a wider selection of destructive spells at your disposal; essentially making it easier to kill enemies with.

You can not charm certain monsters like Bigworm with anything less than 20 charisma, and even then it is a difficult task if your personality is below level 15.
