Only took five scrolls, lol
I threw a phase-by-phase guide on how Static does Kelsaik HM into the Kelsaik's Nest thread in the dungeons subsection. It's a really challenging and expensive fight, but it's so fun.
We have one group that has it on farm status, and we're working on getting a second group (which I'm a part of) through it to also throw it on farm status, because Kelsaik HM is a complete gold mine.
