And when you script a mage, you should always remember there is a chance the mage AI will think it is smarter than you and it will cast spells that are not what you scripted, even if you are in range and even if you have enough gems.

When it is happening it can be highly annoying, as this AI behaviour can then led your army into a defeat if you were counting on a specific spell to save a situation.

I wish there was an option somewhere in dom3 to force really a mage AI to follow exactly its script.

Having an AI sometime overriding its order can be nice in a roleplay point of view, but when it happens when you really need a specific spell to be cast at a specific time and situation, that is just an fun breaker.

But when the AI do exactly what it is ordered to , your army can really sometime do wonders in a desesperate battle.
In my last game my besieged army routed a way bigger army thanks to the casters using the spells i scripted them to do.
