I received this message in my PM box yesterday in regards to the orb...I don't know the person and don't know what it means. Perhaps nothing? I wonder.. It came in this format.
This looks like complete bs but w/e lmao.
Toth and Zorn scream (either visually or literally)
Terror From Beyond literally has a scream (still makes sense to use the orb on either him or the lootable)
Dreadtooth screams (don't know if carnage tried this already though)
