Where do you get the flame ring for shadow in sonic adventure 2 battle?

The Flame Ring is a special item in Sonic Adventure 2 Battle, but you don't actually get it in the traditional sense.

Here's how it works:

1. Unlocking the Flame Ring: You need to complete the game in Hero Story mode with an A Rank on all stages. This unlocks the "Hero" save file.

2. Using the Flame Ring: Once you have the "Hero" save file, start a new game in Hero Story mode with that file. Shadow will automatically have the Flame Ring equipped, giving him his iconic red aura and boosting his speed and attack power.

Essentially, the Flame Ring is a reward for completing the game on the highest difficulty, and it's automatically given to Shadow for the rest of the Hero Story mode. You can't collect it like other items in the game.
