PLEASE READ FIRST BEFORE DOING IT... (BE PATIENT IN READING...)
Go to Practice Mode (I prefer you play GCPH in window m0de...) and Use any Character you want... (I prefer Magician...)
Go to your MLE and be sure to set Scan Type as Exact Value and Value Type as Float (these are located below the box where you put the value you want to scan...)
Go back in game...
In practice mode with your chosen character, Wait until the MP Bar is full...
Step 1 : Press your attack key (default is "z") until it gets to the 3rd skill... DON'T RELEASE THE PRESSING OF THE KEY... Switch to your MLE by clicking it at the Task Bar in the bottom of your screen... (REMEMBER NOT TO RELEASE THE PRESSING OF HOTKEY UNTIL YOU GET IN YOUR ENGINE...)
If you charged up until skill lvl 3... then put or scan 3...
Step 2: After scanning... go back in game... press your attack key or charge your MP until other skill lvls... LvL 1 or LvL 2 skill then next scan it... (REMEMBER NOT TO RELEASE THE PRESSING OF HOTKEY UNTIL YOU GET IN YOUR ENGINE...)... (example you have charged your MP until 2nd skill... then you must next scan 2...)
Repeat steps 1 and 2 until you come up with few address, get the address with the corresponding MP charged... (example you have charged your MP until 2nd skill, you will see an address with a value of "2.xxxx something... example 2.012001202 <-- example...)
If you ended scanning at 3rd skill you will see an address with a value of 3.xxxx something...
Get that and change it's value on the skill you want. Freeze It btw.
Btw, DONT USE IT IN PVPs... ^^
