What kind of magic do you like?

Hello, Philosophers! Question: why discuss tactics against a Priest without an army, i.e., defenseless?:D What can he do? Even if he summons fairies, anyone will still win, but not the Priest. Point 2: I understand that we are considering the case where Mages have ALL the spells of their school, have Warfare skill level 5 (better armor:)), and have no army. And their school level is also at its maximum:). Let's also exclude potions and cases of morale dropping:). Zy IMHO, it's not rational to cast Confusion with a Magic Dragon; it's better to use a Druid to cast Ash Tree and have the Dragon attack with Lightning – it's faster and costs less mana.
