I don't bother with the .xlsm files; I create and edit my mod's Stat txt files directly. I just tried it again and both Leech and Elemental Ranger ignored the "Level 5" requirement I set for them.
The only place that I think a Stat txt file might have an effect would be in the Data/Public/Main/Stats/Generated/Data/ folder, but that would likely run into a Corrupt Main error.
