I've fought this guy maybe 3 times (always in the Adoulin era), but I still don't have any clue how.
The first time, we had a full alliance. It just happened that way. I have a big linkshell, I scheduled the event, and a surprisingly large number of people showed up. It was a breeze until final form, when something happened that made nearly the entire alliance wipe. Two guys were still up and finished him off.
The next time, we had only 6 people. We didn't come quite as close, but we did get banged up pretty good.
What's the best strategy for beating this guy now? I have 2 pops and will need Mulcibar's Scoria fairly soon (10 days away from completing Yagrush!!!) and can probably summon linkshell mates to assist. You'd think I'd have some experience by now, but this guy flusters me.
