No Damage?

I have experienced lag in the game, and that affects the way mobs shoot their skills, even tho if im not hitted by anyone i will not receive damage nor die.
I was wondering if it is possible to do a hack that affects the missiles that mobs uses, either the damage or just remove them from the game.

It is possible, you'd just need to decompile the .swf, find what code makes the enemies launch missiles, find what set of hexadecimal data it writes to, replace that hex data, and bam, no more getting hit.
I'm too lazy to do it.
