Dragon Age 2 - Staff of Parthalan In-Game Item

I received an email from EA last week with a code for an in-game Dragon Age 2 item called the Staff of Parthalan.  Apparently I signed up somewhere or other.  I meant to post about it but, not being a fan of these in-game bonuses, promptly forgot.  The Grey Wardens site has posted a quick explanation of how to sign up, so I'll link them instead.
