I have looked at my active effects and no where do I have something that lowers weapon dmg.
I have the same gear on and same effects as I did when the following upgrades were done:

Mace of Molag Bal: upgraded to 54 wep dmg
Okin: upgraded to 51

Both of those weapons have full magic recharges but now display the following dmg:


Mace of Molag Bal:49
Okin: upgraded to 48

Is there something I am missing or is the game randomly changing my weapon's dmg?

Not sure you're in the right forum but you probably changed out a piece of armor that had +% one handed damage for something else.

I already noted I was wearing the exact same gear now that I was when I upgraded the weapons.

go into magic, then active effects , make sure u havnt contracted a disease. if you have drink a cure disease potion or activate a shrine. hope this helps

o didnt see that u checked it already.

is it possible that u had an active effect that was increasing your damage? such as a shrine as these effects are only tempoary
