One of the masterpiece that stunned me in awe. Decided to record it in-game and keeping it until i can buy the official one when there is one released. 

Have a very hard time pinning down the amount of instrument that is actually played for the combat version like this one as they were somehow kinda spread and seems to tied to the enemy's aggro and sometimes few enemies at a time.
