Didn't even break a sweat. He (she?) opened the fight by casting Flare, which was generous as it gave me a good 15 seconds to whittle away and use a Sekkanoki'd Gekko -> Kasha Fusion SC on him. Silence from Gekko didn't stick, which was annoying, but hardly problematic.
Immediately after using his 2-hour he began casting Waterga III which I stunned with Blade Bash and after that the fight was fairly unremarkable. Looking back at the chat log, the only damage taken was from his Blaze Spikes. Drops were 6k in gil and a coat.
