Today I received yet again the black feather helm in the unnamed city.
This time my character had all the siptah sigils active and I got NO corruption added so I thought it might be related to the sigil that helps remove corruption.
I went into a solo server and tried it again but that sigil that removes corruption (as I had it running by itself) did a little to eliminate the corruption and seemed to work as intended by removing a little for which the helm continued to add more. I slowly added all the other sigils and… it would not remove the rest of the corruption.
I took the helm off, healed up and put it back on and the helm did not remove the corruption.
This is as much testing as I have done on it.
Has anyone else run into this?
Am I not seeing a intended reason for this?
