Spell Fatigue

[Whismerhill]

1) Pvk is true
the unit regain conciousness once its fatigue hits 100 and less
and (and probably the unit will do something and re-lose its conciousness again)

1a) yes
1b) 200
1c) yes
2) yes
2a) yes
2b)yes
3) yes

4) don't know
4a) this one neither

5) yes

globally the most powerful casters are those than have not only power but also some kind of reinvigoration to allow them to keep casting & casting & casting

if you could reduce fatigue to zero on a necromancer of example
in a deathmatch condition it could be very difficult to get to hit it in melee as he will keep casting undead & undead
(in deathmatch arena it happens often that somme AI fighters are overrun by the undead of ermor)
