Diablo 3 Help

Hi guys i was woundering if anyone could tell which file i need to change in my save to mod paragon 100
because if i mod a character into my save the level dosent stay a para 100.

 

the account.dat file

 

does that change whats in the stash or not.

 

i know hex a little, but in the file account.dat i dont see anything to change. Someone can tell me where change in the file? is it encrypted?
