I believe the mask is directly connected to the Plague Doctor and the “Tragedy of the Hanged King” SCP. It’s also connected to the city of Ala Gadda (or however it is spelled).
@perck@xyzzy I guess it would depend on two things: One, which object was worn first to be overridden by the second; and Two, does the liquid from the mask corrode the amulet?
They should let 1 d class personnel wear the mask and let the mask anomaly talking with the "gayest man alive" maybe if both of them together, the mask effect will be negate.
