West had been sitting quietly so far, but listening for sure. So far everyone was saying about creatures and all so when he put his hand up,
"Aside from creatures, where Flying Carpets are legal, they have to have a disillusionment charm on them too. Basically its one of the primary charms for protecting the International Statute of Wizarding Secrecy."
As for scenarios....
"If you wanted to make someone think that you'd cracked an egg on their head, you could cast it on them?"
Y'know, since that was how it felt when it got cast on you and all?
