Seeing as dragon saga doesn't have any type of anti-hack shield or anything I decided to give cheat engine a whiz to see what I can do with it. I have very little knowledge in terms of hacking but I try my best. It seems the reason gravity doesn't need any anti-hack shield is because almost everything is server-sided. I did however managed to freeze mp points by searching up the mp points in the cheat engine and freezing it. You should get about 5-6 addresses when u search for the mp. I froze all of it and tested it on my monk. I was able to use the revive skill(which takes up like 60% of my max mp) 4 times and more after waiting for each cooldown which is like 45 seconds I believe. Maybe somebody else can test this out to confirm that it works. Also, it seems you have to search for the addresses every time you move to a new map. I'm still working on freezing hp but no luck on that end so far.
