During the gameplay, you can use 3 stances: Balanced, Heavy, Light. Balance beats Light stance, Light stance beats Heavy stance and Heavy stance beats Balanced stance. Each has it's own features and weaknesses,
Light Stance Edit
Light stance has a big slash range and it's the most popular stance to older players because it gives more of a challenge, it's feature is light stance launch, which gives you the ability to keep the opponent in the air, however it has low damage.
Balanced Stance Edit
Balanced stance has a balanced amount of damage and defense, however, it has lower power then heavy and smaller slash range then light, so if needed more of those, switch stances.
Heavy Stance Edit
Heavy Stance does a big amount of damage, but in return, it makes you more open to the enemy, basically, your defense from the enemy is weaker.
