an angle, then start nuking them. When they unstun they take some time
to turn around to look for you, when you notice this, stun them again."

I reply:

I'm don't know if this is good advice. For one thing, the lower level
stun lasts only two seconds. By the time you've run around the caster,
he's not stunned anymore. For another thing, the recast time for stun is
very long. And, if the caster is smart, he won't turn around to find
you. He should already have you targeted, and he'll just hit his cast
button. He doesn't have to see you to cast a spell. And, if you're
dueling, he should realize that you won't be outside his casting range.
I think Flash of Light would yield better results. It lasts much longer
(12-18 seconds, I think), and he cannot cast while blinded. If you want
to confuse your opponent even more, cast Fear on him after you've
blinded him. He'll never know what hit him.

This from having dueled nasty necros in Lake Rathe. They really hated it
when I Feared them, heh heh.
