Phantom Breaker: Omnia

In order to unlock this trophy, you will need to deal an accumulative total of at least 68,000 points of damage across all game modes. Thankfully, like most trophies in the game, you can unlock this trophy in Training Mode since you can also stack this with any of the other trophies you have yet to unlock.

If you follow the same method used for Dedicate this Avatar to the Gods , you can easily unlock this trophy by using the Omnia Style's All-Range Attack ( when your meter is full (400%)) at least 15 times or more depending on the amount of damage that is dealt each time you use it.

You can keep track of your progress towards this trophy by going into Records in the main menu, and then go to Play Data. While you are there, press  to go to Achievements and you'll be able to keep track of your current progress towards this and the other trophies that require you to perform a specific amount for certain actions.
