I don't understand the question. Mind Control is a shadow spell. It is not affected by either intellect or spirit, except to the extent that you have enough mana to cast it. It can miss, so your hit will affect it, and it can be resisted, so a mob with shadow resistance has an increased chance of resisting or breaking it early. The controlled mob/player retains its own stats, health, mana, and abilities, so your intellect or spirit or other stats have no impact there.
