Superior Sigil Of Leeching Triggering Bug
reported this a few times myself quite a while ago, simply stopped using the sigil as it was only even questionable if it worked correctly, definately not worth using as is.
It is being consumed by skills that should not consume it. It is a bug.
There are many similar bugs. Probably low priority, which is why they still exist.
Playing Devil’s Advocate since 1990.
My problem is that there will be long periods of time in which it just plain doesn’t do anything. No buff icon, no nothing. I too am a thief, so maybe there’s a connection there. I have one Superior Sigil of Leeching on each weapon set, with the other 2 remaining sigils being Luck and Agony. Could these be interfering?
