Transference - Cast on yourself instead of your normal move. Switch spaces with any other character in your Region.
This is a very, very powerful spell! As long as you can get to the Inner Region, you can bump out a character who is at the Crown of Command, taking his place, and you don't even need a Talisman!
My Wizard used this in a come from behind desperation bid to defeat the Elf who was at the Crown of Command. I picked the lock on the Portal of Power (Craft 5, rolled a 4). I then moved to the Plain of Peril. On my next turn, I cast the spell and switched spaces with the Elf, and used the Command Spell to kill him, winning the game.
I keep this in mind.
