Fatigue 100- ?

[LDiCesare]

To clarify.
All spells with a cost of 100- cost 1 gem.
That's what Soyweiser said, but it may not be clear enough.
The ai does not care about fatigue when deciding to cast a spell. It cares about gems.
So if it decides the enemy is puny and not worth spending a gem, it won't cast the 100- fatigue spell because it won't burn a gem, not because of the fatigue.
The ai will cast the spell if there are valid targets etc. and there are enough gems available and the enemy is deemed worthy.
It does not matter how much fatigue you currently have. The spell will be cast. The ai will try to burn gems to reduce the spell fatigue, and I think it's more likely to do so when you're already fatigued, but the effect is only on the number of gems you burn.
Also, I think the manual states a mage casting a spell can't get over 200 fatigue from the spell itself, but I never checked that.

Thanks, guys.

Sorry I made mistake about not realising every 100- fatigue spell costs 1 gem, I had not noticed that. So, I meant in my example the guy does have 1 gem, but no extra gems, nor extra expertise levels, to reduce fatigue.

It seems from your answers that he doesn't care about the fatigue, which is good, as it makes it easier for me to script!

But there must be a limit? Correct me if I'm wrong, but there are some spells with like 400- fatigue. If I script a mage, and he has no extra gems, no extra levels and isn't doing a Communion or similar, I should be quite happy if he killed himself casting it (I believe 400 fatigue kills you?), but will he commit suicide for me?
