Exaggerating much? Body of Air - 25 (2 every 10 seconds) fatigue Shield of Force - 5 (1 every 10 seconds) fatigue Summary: Casting both spells costs a measly 30 fatigue points (a typical character has more of them at lvl 1) while maintaining them costs 3 fatigue points every 10 seconds. A normal human being has a heal rate of 3, while a wise mage should have twice as much, so I really don't see how he would run out of power just because of that. I do not recall it ever being said whether or not Preator's counsellors could be even considered battlemages. Not all magic is combat magic, just like not all technology is combat technology. We don't know anything about their number nor practice (could have very well been a handful of lower tier Tullan mages), so saying that technology is more powerful than magic only because those particular mages didn't fancy fighting an army of riflemen is like saying that magic is more powerful than technology only because an average herbalist won't even try to defeat a wizard skilled in the Force college.
