Ok, this is driving me nuts.

Got Overseer's Guardian CR, modded it a little so it was doing 120 damage for my character. After a few minutes of play, I suddenly see it is only listed as 114 damage. I can't for the life of me figure out what is diffrent.

I changed my armour a little, a leather leg piece to a combat armour piece but neither piece had any SPECIAL bonuses or legendary bonuses. I have checked my status, it hasn't changed. Haven't levelled up. No illnesses or radiation sickness. I went back and forth between a couple different saves and I can't see any difference but my rifles are suddenly doing 5% less damage. I changed the difficulty from normal to hard but that doesn't have any effect on listed damage from what I can see.

If anyone knows what I'm missing I'd love to know, it is insanely frustrating. Is 5% the amount 1 agility point would have? I keep thinking I lost a point changing equipment but when I go back and check saves my stats are the same.
