Yeah I know, a tad late, although admittedly, even if I'd posted these a week before Brewfest they'd probably be too late, so think of this as being posted in plenty of time for next year. ;-)
Tailors could make the brewfest clothing.
LW could make the shoes.
Engineers could make the beer goggles.
BS could make a beer-meister (simular to pony keg).
Alchies could get a beer-themed potion.
Enchanters could get a weapon buff "drunken stuptor" that would cause a stun or daze proc for a few seconds.
