If you need me, I can lend a hand. I can't play until 1st July, so my job levels will probably be fairly close to what they are now (BLM71, BST65.)
I have the paintbrush (need just one for the whole alliance) and I'm pretty sure I still have an unlit lantern hanging around (need four for the whole alliance - assuming everyone gets through the door in time.)
I can solo the lantern dropping mobs with my BST (can also solo the ones that drop the key for the Paintbrush, if you want one.) So I could take a group of people off to farm those, maybe a few days before the marathon run? Farming them with a THF would be preferable though, as there are only a few spawns in the area with pets so it can take a while to get enough drops.
I've beaten Kam' two times, and the Magic Pot NM also two times, so hopefully those fights should go well :)
