Elemental Weapon

Your blood sings with the song of battle and the elements. Perhaps you were born to a well known general or battle mage, or perhaps you were born in the middle of a raging elemental battle. Only you know how your blood came to course with the need for battle and weapons. Your ability to create a weapon from the pure elements might be seen as strange to some, but to you it is as natural as breathing. What need have you of forged weapons? You can summon the perfect weapon to silence your enemies from within yourself.
