Things in maplestory that rustle your jimmies.

These two quests will already get you halfway if you haven't done so already: Pap's prequest and Eliza's Eternal Sleep.

I'm already at 87 fame and have done both of those so I think the easiest would be to do the Goblin Cat quest. And while I'm at it fame requirements to enter maps are stupid because there's got to be tens of thousand of Evan hackers bypassing it anyway!
