I thought it was pretty good.
I would like to have seen more lore involved. For me, most of what I saw/heard went like this: OK, there's some crazy monster running around, avoid it for now. Turn in these random pages that are dropping all over the place so we can hurt it in like 10 days (maybe get some fat loot while doing it, probably not though). Do fat damage or fat heals when we fight it and maybe get fat loot that way too.
Some staff Broadcasts, or maybe a slightly altered area as a result of the monster breaking things could have fixed that. It would have been cool if maybe it was blocking a path to a new area, or even an existing area, and we had to kill it to (re)open that area. I don't know, something like that. We killed it, and that was the end of it. NiteHawk said something along the lines of "The realm is once again safe" after we killed it, but I never felt unsafe.
As for the boss fight, I liked most of what I saw, nothing seemed new though. Paralyze, some dots( I think ), fat damage, mass confusion. Good times, but I wanna see more!
He died too fast I think as well.
Overall, not bad, not bad at all. Thank you to the staffers and to NiteHawk for putting the time in. I hope we see more stuff like this in the future.
