Something is really annoying me.
I have read a lot of Conan books.
Some combination of these is why Conan manages to defeat a Caster in the books (many of these apply to the monsters he fights as well).
a)The caster is incredibly arrogant and stupid, giving Conan a chance to do something surprising and ballsy.
b)Conan has or finds a maguffin that saves him (this includes having a friendly caster along to protect him, which happens on occasion)
c)Help shows up and saves Conan from being killed by the caster in the nick of time (typically this works because the caster is distracted).
d) The caster is really weak e.g. can only put up a small force shield for a short time, and is apparently incapable of short range offensive magic (which in the Conan setting frequently amounts to "Lighting bolt/Magic Missile, you have a 3 inch hole in your chest, GG").
e)Conan sneaks up and gets a surprise round. Repeated broadsword stabbings are reasonably effective against casters. This frequently plays out the same as c), but with Conan doing the saving.
Conan cannot go "Toe to Toe" with a caster. Almost every time he has tried he has lost horribly. Often the only reason he survives is that casters in the Conan setting frequently don't seem to understand that "Death is not too good for (their) enemies". Seriously, Conan is the most ballsy, brave, strong, heroic, lucky SoB in the entire Conan setting, so much so that by the time he ends up King of Aquilonia he is a legend throughout the known world. He is literally favored by the god of light. Still, for most casters it's very clear that the game is theirs to lose, and they lose it because they are generally power hungry idiots who have a complete lack of genre savvy paranoia that the typical PC wizard displays.
In a game of pathfinder, wizards and clerics and what have you do not have any compulsion to act like morons.
They will not betray Conan, the person who saved them moments ago, by leaping to a nearby pull rope and then...
So this is basically the funny version of what I've been trying to say(and clearly failing, by all accounts).
