Choice of things to do when you have the high ground:
1) Shout at those who make their way up "ITS OVER ANAKIN, I HAVE THE HIGH GROUND!".
2) Use lightsabers and quarter those who make their way up. It will be a fight to the death for the high ground.
*Lightsabers not provided. Only the high ground
*do not actually climb on top of merlion don't get us in jail kthxbye
