this sounds excellent c: i don't think Loki would make another network post so soon about the poisons, but if there's an IC team moon meetup/network post or something along those lines, he'd offer his services.

and illusion powers are a go, then! if he's able to gather a bit of information on the location first, he could always put a few things together. he spent a thousand years in Asgard, and the palace there has it's own weapons vault and secret tunnels here and there, so i'm sure he could at least generally suspect where the tooth would be. it's a little possible he could sense the radiating face-melting energy too, but probably not from afar.
