Wizard 101 Guild: A Tour of Battle Island and Crafting Raid Keys

The Voracious Void Raid
The Crying Sky Raid
The Cabal's Revenge Raid
I'm sure you have all heard of raids, but do you know how to craft the keys necessary to unlock them? You'll need a lot of azoth and some specific monster summoning treasure cards. (Hint: You will need some monstrology skills.) When you're ready, talk to Gwyn Fellwarden on Battle Island to craft the keys -- and to craft the loot if you have won the raid. Are you up for the challenge?
