FearLess Cheat Engine

Can anyone please explain how does UnlockSpellVariant work?
They refer to xSpellCheck() or xActionCheck() , but I can't find those X in Stats/Generated/Data txt files.

I want to make Hightened buffs similar to MAG_Heightened_Necromancy_Passive, for every magic school, but I'm stuck in a deadend.

Bug report: DNA "gene_jaw_width" doesn't work, it has the same address as "gene_head_top_width".
Tested on multiple characters, without mods.

UPD: Fixed the issue by changing the "gene_jaw_width" address from +50 to +60
