Luck/PERCENT MAGICAL DROP/magic find. Not sure how best to call it but I am trying to find a way to reference it to augment abilities.
Progress so far:
I know from looking at the synergies mod that it is possible to mod in new stats, and some of them seem to auto-calculate without having to specially link them:

[STAT]
   <STRING>NAME:CHARACTER DEFENSE
   <INTEGER64>UNIQUE_GUID:-7233122499928127780
   <TRANSLATE>DISPLAYNAME:CHARACTER DEFENSE
   <STRING>TYPE:TYPE_PREDEFINED_INT
[/STAT]

So I tried to make my own stat for luck

Spoiler (hover to show)

[STAT]
   <STRING>NAME:CHARACTER PERCENT MAGICAL DROP
   <INTEGER64>UNIQUE_GUID:8143476688288407776
   <TRANSLATE>DISPLAYNAME:CHARACTER PERCENT MAGICAL DROP
   <STRING>TYPE:TYPE_PREDEFINED_INT
[/STAT]

I names it "PERCENT MAGICAL DROP" because that is what the game calls it when it boosts magi find via magic dice or yololo skull.
However when I attatch that stat to an ability affix via:
      <STRING>STATMODIFYNAME:CHARACTER PERCENT MAGICAL DROP
      <STRING>STATMODIFYPERCENT:5
      <BOOL>MODIFIERISBONUS:true
It does nothing as I equip/unequip luck boosted items.
I tested the affix attatchment by using "Max Mana" instead and that one did work.

What am I doing wrong?
Is there a better way to reference the magic find stat the game keeps track of in the "j" menu?
Thanks in advance

P.S. I have Guts but find it easier to work in text files and just let GUTS compile it at the end

Hi Oleg! Welcome to Torchnodders same here unfotrunately, stats and affixes arent my bag. Ah so u also prefer to edit the files directly? a kindred spirit!

Hi Oleg,

A couple things.  Your two stats, PERCENT MAGICAL DROP and CHARACTER PERCENT MAGICAL DROP, are not linked.  They're two different stats.  So, modifying CHARACTER PERCENT MAGICAL DROP isn't going to modify PERCENT MAGICAL DROP.

Also, check out the list of static stats that already exist in the game here.  Searching that shows a likely candidate for a stat that might already fill the role you're looking for, 'CHARACTER MAGIC FIND %'.

I hope that helps
