Only a bladesinger can take this paragon path.
In the paragon tier, you continue your intensive study of the ways in which sword and spell can unify into a single weapon. The bladesinger’s path is both a highly formalized tradition and a deeply personal journey into the secrets, of magic, swordplay, and the self. As your journey continues, you come to grasp ever more powerful spells, and magic plays an increasingly important role in your drive to victory.
