Water 2 mages are good for casting "voice of apsu" and search those cool magics sites. As for fire 2 cast "augury" and so forth.
It´s good to blood hunt also even if you almost never use it in battle. ( I casted once a battle blood spell on MP to give strenght to all my units and then some vampires and devils killed 2 enemy air queens )

+strength blood spell would go well with a mictain blood+fire bless (which would give even more strength to their multiple attack, flaming sacreds)
