I seem to remember a long time ago that there was a thread and/or publish notes that talked about the chances of artifact drops decreasing when you were hidden or using pets. Taking for example 10th anniversary arties: To the best of my memory, there was something said in relation to players using strong pets while hidden and camping them in anti-virtue dungeons to farm arties while unattended. I believe that as a measure to counteract this, something was done which reduced the chances of getting artifacts if you were hiding and/or using a pet to do the damage alone. Is someone able to confirm this for me, and if so (a cookie for anyone who knows), can they answer the question of whether or not luck is affected in any way? I know that this is a tricky question, but maybe a dev can provide some assistance on this matter!
