Out of nowhere none of my upgraded weapons are doing hardly ANY damage, help!!

I just got the lord vessel and unlocked the sealed areas. Out of nowhere, none of my weapons are doing over 40 dmg to anything.

Ive checked that none of them are broken, there isnt some weird debuff i have on, and have tried on several different types of enemies. I have a +4 quelaags furysword that used to do 270 dmg but now does a little over 40. Tried with several other weapons as well and same problem…. Restarted the game to see if that did it but same problem.

Ive put almost 80 hrs into this run so any help/recommendations are MUCH appreciated!
