Armed Mages
Mages are not just magic casters, Once you have acquired the Arcane Warrior style you can easily exchange the strength of armor and weapons to wield or wear them for Magic. You can now use spells and a sword. Do not worry about taking physical damage because of the armor. You do not have to keep your distance and use all the spells desired and still get up close with your enemies. Note: This ability is obtained in the "Nature Of The Beast" quest with the Dalish Elves. You must go into the temple and find a vial that seems odd. A short cinematic starts and it speaks to you. After a long series of questioning, it offers to pass on its talents of an arcane warrior to you and your party in exchange for its freedom.
