Praxis is a Rare Blade in Xenoblade Chronicles 2. She can grant tremendous power to her Drivers and their allies. Praxis uses the water element, wields a Megalance, and acts as an Attacker in battle. She moves like a skater on ice with an elegance reminiscent of a fairy, similar to Theory, another female Blade with whom Praxis shares a bond. Praxis is kind and a bit sassy at times. Theory, another blade is like a sister to her who she is caring and supportive to. She previously was a criminal.
