The beautiful in the Sora weapon is balanced in his skills against monsters but what make him bad is his skills in fencing and the speed of his attack for this is better you add the advantage of the speed of attack in the skill of the enchanted shield and you changed the skill of striking the finger skillfully characterized by fainting because this is actually what is missing Sora weapon.
This was my opinion in the character of the Surra weapon. I hope you understand and thank you. I wish you all the best and good luck and happiness with safety
