could the event in question be the one with the variable clubs as rewards? there are a bunch of them in AH history (varying level requirements, all jobs) and they all have MP+1% HP+1%.. nothing spectacular, but could be useful if skilling up club on a job that doesn't have many options (Bard does come to mind >_>;; )
i seem to remember all of those clubs being named for critters in the chinese zodiac
