warriors orochi 3 ultimate mystic weapons glitch

If you have two controllers, you can obtain mystic weapons much easier.
First, select your favorite mission with a character who ever have obtained the Mystic Weapon yet. I recommend playing with Zhou Tai of Wu and stage Chapter 1: Counterattack at Nagashino. This mission is the fastest mission to obtain mystic weapon I found. You MUST be playing on hard or chaos difficulty for obtaining the Mystic Weapons.
Join 2P with the second controller and select characters you want before mission start.(Important: Any characters which you want to get a mystic weapon should be same column of 2P characters with Zhou Tai at this time
ex. 1P Any Character - Zhou Tai - Any Charater
2P Any Character - mystic weapon need character - Any Character )
Collect the weapon with 2P after meet the requirements for the Mystic Weapon and finish the mission.
(kill gatekeeper - Sun Wukong1 - Sun Wukong2 - Yukimura Sanada - Get Mystic Weapon in the map center - Sun Wukong3 - clear stage)
The weapon will be added to your 2P character's inventory.
