I’ve seen way too often people try to describe that bug by elaborating multiple cases.
This is how the bug can be described in a simple and easy to understand manner:
Notes:
This will only affect melee attacks UNLESS you bugged both the min and the max dmg, in which case ranged attacks will also be bugged.
Non-bugged ED% already there prior to the bug will be unaffected.
+Min/max dmg is always still working, only the ED% can be bugged.
Please confirm if you received your fg? If not you might want to make a scammer accusation.
