Cheat Engine 6.0+ ( Actually I don't know but it works on 6.0 and up )
And common sense.
Recommended Browsers: Internet Explorer
Steps
1) Go on Maplestory Adventure
2) Open cheat engine
3) Select your process
4) Find out how much power you have ( Below the EXP bar )
Lets say I have 210 and I'm wearing a hat
5) Type in 210 in Valuebox and Scan
Now a bunch of things should've popped up on address box.
6) Wear or take something off to lower your power
I take off my hat and I have 205 instead of 210
7) I type in 205 and press next Scan
Now there should only be one value now on the left
8) Double click it and send it to your table
9) Change the value to the amount of power you want
Has to be 300 - 400 Greater than your actual value so you won't disconnect and
it may say you still have the same amount you had before but after you attack something you will see dramatic changes
I don't know why you people say its not working so here's a video
NOTE: Credits to whoever made this. And if it says some blackmage **** just press X
