Chain Casting -> Fear -> F. Ball -> MM1 -> M. Burn -> M. Blast -> Fear -> I. Blast -> F. Ball -> Stifle -> M. Blast -> Dead.

If they use extenders, drop Frost Novas and Infernos on them.

I had high criticals back then, so that chain above drops most clerics with 4k+ hp. If less, subtract spells. This is with stones.

acually, it kind of sound like a mage to me...Uruga sounds dark/mysterious to me...kind of like a dark elf :)
