This was just the first form/battle, but a fun battle. As usual not too many people showed up, we had only 10 people, no BLMs, and 1 SMN that ended up having to mostly cure instead of doing damage since we were a bit short on healing. I didn't have all my MND gear on (30 less than my usual), but chi blast still did surprisingly well.
Meleeing and using Hundred Fists also did
very well, as usual DEX >>> STR for monk here, critical hits were really the bulk of my damage (even war often hit for 0 on normal hits and 60+ on criticals, and i did 90+ on criticals with my trusty mitkabobs).
Toward the end it got a bit hectic, many died from gigaflare except of course the high hp monk :) and a benediction and my ninja sub allowed me to be in good shape to finish it off.
