You know what this thread reminds me of? Zack and Aeris rumors from FF7.

I beat him with Kira as my companion at level 25. Vigilance spec'd. It was tough, but if you time your interrupts (Kick/Stasis) you should be able to get him. Send in Kira (or t7) watch their health, taunt off, ward up/medpac, dead Lord Praven.
