Yeah, Rotating Schedule seems to be the case. On the 15th, the new Event Quest is going to be a match versus not one, but two Barroths (Very likely simultaneously, ala the Double Royal Ludroth fight that was present earlier). Victory nets you a piece of the HellHunter Jacket - which is a really damn sexy black leather jacket with three slots and +5 to Survivor naturally. There's also a white version to come from a later event, which gives +11 to Survivor, but doesn't come with any slots. Oh, and there's a pair of leather pants coming too... and some awesome shades...
Suffice to say you'll look out of place, but damn good BV
...Well, if you can take on TWO GODDAMN BARROTH anyway (And there's no telling what the other event challenges are going to be ;-;)
Also: You can invite people into the Jhen Mohran urgent if they're at 27 or above, apparently. I've still got a few HR to go, but I'd come along if I could XD ... in the meantime I need to keep farming Lagiacrus to get the last Horn I need to complete its armor set... and hunt Diablos and Rathalos... and probably forge myself a few other weapons... sigh.
