Arkhamites,
Let me apologize up front if this is one that has been answered before...
I know that you can't take a Spawn Monster as a Trophy . To my knowledge, Spawn Monsters are never returned to the cup/sheet etc. due to a Gate Closing/Sealing (I think that's because they're assosciated with the moon/crescent dimensional symbol). Okay here's the question...when you have one of my favorite Mythos Cards which states that locations and/or streets are cleared of Monsters...does this apply to Spawn Monsters? My gut tells me no, but I need to hear from the community.
Thanks,
The Professor
