Massive fatigue spells

[thejeff]

A mage can't use more gems than he has levels in that path.
So an S8 mage can only use the 8 gems to cast Master Enslave and none to reduce fatigue.
A S7 mage can't cast it at all.

IIRC, a mage can only use 1 gem to boost his path to actually be able to cast the spell, but can use more to reduce fatigue.
Eg., Assume a S8, 4 gem required spell. An S7 mage could use 4 gems for the cost, another to reach S8, and 2 more to reduce fatigue, reducing fatigue to 133.

I suspect the AI will happily use gems to reduce the fatigue from high cost spells, even if it remains above 200.
Eg., Assume a S8, 5 gem required spell. An S7 mage could use 5 gems for the cost, another to reach S8, and 1 more to reduce fatigue, reducing fatigue to 250, which would be capped at 200.
