Okay, after spending quite hours on GG,
i find a static group value for level hack ( i use new game save to test it, and it might changed for each devices, i use v1.730 fa)
Search : 112;4;0;0.5E;1.75F;3;0;5;68;16,842,780
Default Group Type: Dword
Im unsure about the ordered value, i use default :512 and also those group search are offset-ed by 4 (as gg offset calculator suggested).
**64 - **68 = 4
This group search will gives you 200+ results
now filter it with
Filter : 0.5
Type: Double
Now, you should have 1 results ( 0.5 Double),
change it to 1,
Do search/hunt, something that adds levels, and you should be lvl 100 after that, feel free to revert it back to 0.5 if you want.
P.S
I also tried on my other profile that's level 49 and it works fine, it'll not go beyond lvl 100.
for perk it'll gave you 91 in total
