Blazefire Saber

Blazefire Saber (ブレイズエッジ) is a gunblade with fair, balanced attack power and no special abilities. It is Lightning's signature weapon. It is the only gunblade which appears in cutscenes no matter which model has Lightning equipped, due to the cutscenes being prerendered in Final Fantasy XIII.

Final Fantasy XIII
Blazefire Saber is a first tier weapon available for Lightning. It is Lightning's starting weapon and can be obtained from the Retail Network Up In Arms for 2,000 gil. It can be upgraded to the Flamberge by using the Perovskite item, and provides physical defense as its chain ability.

Despite the Blazefire Saber's lack of abilities and low attack compared to some other gunblades, its use as a balanced weapon between Strength and Magic makes it useful for Lightning, as she is balanced herself. Using the Blazefire Saber allows her to switch easily from physical to magical attacking, without a loss in comparative attack power. It also requires fewer Experience Points to be leveled up compared to some of her other weapons.

Dissidia 012 Final Fantasy
The Blazefire Saber returns as Lightning's weapon. She wields it in all of her alternate outfits and in both of its forms (sword and gun).

The Blazefire Saber is also a level 1 exclusive weapon for Lightning, found in a treasure chest, and also able to be crafted, making it possible to own multiple copies. It raises Lightning's Attack by 11 points.

The 3rd Birthday
The Blazefire Saber appears in Square Enix's Parasite Eve spin-off game, The 3rd Birthday. It is an unlockable weapon for Aya Brea, along with a costume based on Lightning, as part of Dissidia 012 and The 3rd Birthday's tie-ins.
