Battle mage refers to four groups of melee spellcasters. Scryers are known to have battle mages in their ranks. They are likely to be former members of the Kirin Tor like the Scarlet battle mages.
To recreate this look :-
Shoulders :- Warbringers Spaulders
Chest :- Enchanted Thorium Breastplate
Waist :- Girdle of the Dawn
Legs :- Enchanted Thorium Legplates
Feet :- Grim Sabatons
Hands :- Exalted Gauntlets. Can't see exact gloves but these match.
Tabard :- Scryer Tabard
Sword :- Blood Groove Blade Needs a firey enchant.
Shoulders aren't exact but I like them better than any look alikes I can find. Here is the set without the tabard.
