"When this card enters play, spawn the Crazed Elder Thing Epic Monster on Miskatonic Outpost. It cannot lose Health, unless the the active Investigator has the Alien Device Artifact."
"If you defeat this monster during a combat encounter, you may gain one Dark Pact Condition to discard 1 monster from any space."
The mystery card says that the monster cant lose health unless the active investigator dont have the artifact but the effect on the goat spawn card dont say that the monster loses any health, only that it is discarded. So my question is; can i use the effect on the goat spawn card to discard the crazed elder thing, and solve the mystery, even tho i dont have the artifact?
