Some mages specialize in spells that permit them to engage in combat from afar. Battlemages, by contrast, prefer to wade int othe fray alongside their blade-wielding companions, close enough to read the fear in their opponents' eyes. Their spells primarily concern personal preservation as well as control of the elements in their immediate surroundings.
This specialization is only available if you have the Dragon Age: Origins - Awakening expansion pack installed. It also requires a minimum character level of 20. After acquiring the specialization, the character will gain access to four new talents
and be granted +2 magic and a small combat health regeneration bonus.
How to Unlock:
