The shiknar in paludal caverns next to the Reishicyben room at loc 1655 627 32 cons indifferent when you have bard invis, but agros anyway. I can see putting something there that sees, but then it shouldnt con indifferent.
I *believe* the Reishicyben Aura that is also targetable for some reason in this room for the quest "Big Claim Hunter", is what is causing the invis to drop.
I was taking some spell damage from an aura while in the hallway close to the Reishicyben that I think was breaking invis.
Youre right, my bad. Went back and tested, and even if that one is already dead invis wont stick for more than a tick. Thats some trick.
