The perfect Maple boss fight

I still like the idea of an attack that could ohko everyone though, but make a safe spot in the map, and give it a long animation. That way it gets really frantic when everyone trys to scramble to a safe spot on either end of the map to avoid the attack. Of course, people who view bossing as just a buisness would be annoyed by any sort of fight like this, they just want to apple/spam attacks and make profit.

Edit: Of course this attack wouldnt occur very often, that'd get annoying, but if they throw it in every so often it'd be cool, they could even have blue text that says something like "[Boss's name] seems to be gathering energy, quickly! Flee to safety!"

I dunno, I like it =P

What about something like the Zakum Pillars or Pianus Weights?.
Something that would fall from the Ceiling hitting the players on market spots. I'd would have to be slower so that the players have enough time to move to a safer spot, and it would need more space between the places where the attacks will fall on.
