I'm trying to lower a few stats for a custom character, like one-handed which is at 20 for its lowest level. I can add a positive offset which works just fine, but nothing changes if I add a negative offset.

The reason I want to do this is because I'd like to make a boss fight that lasts longer than most other fights, so I've raised the actors' health but to make it fair I want to lower his attacking power in return.

Thank you in advance!
