I was just watching the Majestix Open Series, as a match was put online, and somebody moved then dropped a hammer for the free quake?

I thought dropping a hammer was a beginning of your turn action? Just curious of what I'm misunderstanding, thanks!

Equipping a Character - At the beginning of each of your turns, you may remove a Hammer from The Book of the Skull and place it in the square of a friendly character that is at least 5 squares from any starting area
