How could I avoid such a thread?!?!?!
Paesants: hey, just hit them with fists. They'll sleep like kids.
As for killing them accidentally, it WON'T happen, 'cause
you WON'T cast area spells with people around, will you???!
Party Members: every effect has its counter-effect.
Not a problem, Imho.
Remove Magic works when they're red.
And you can always have Immie hit them with Staff of Magi in the
head (low damage), and dispel everything that way
(as someone said, sort of "what's up with you?!?!"

)
Or you can simply wait for the effect to wore off,
avoid their attacks, go invisible, cast haste and run...
Or again hit them with fists.
Real Enemies: eheh, here comes the fun!!!!
Not always possible, though.
You have to be dedicated!
Memorize G. Malison, Doom to lower their saves.
Then go with Spook (up to -6 save), symbol Stun (-4 save),
Horror, Emotion, Hold Person, Web, whatever.
They'll lose sooner or later...
Avoid being killed while at work!
The Glaicas encounter is bugged, but there's a fix out there.
