Are you supposed to be a blood mage in DA2?

I noticed in DAO from the wardens calling trailer and the sacred ashes trailer you were supposed to be a Templar Tank Warden with wardens armor and shield from the one dlc. By the destiny trailer it looks like you are supposed to be a blood mage. Is that what he is or is it just some random spell he uses in the trailer? If you notice he re-burns the tattoo into himself which i thought could just be blood magic but maybe i'm wrong i dunno.
