Castlevania Aria of Sorrow Walkthrough Part 7

Walkthrough of Castlevania Aria of Sorrow, New Game+ with the use of all souls and the Chaos Ring to avoid leveling and soul hunts.
This part resumes the fight against Legion and ends with the demise of Balore.
We get one new ability: Galamoth, which allows me to wander in areas where time has stopped. Not really useful to this walkthrough because I won't go to any part in the castle where time is frozen (it's optional), but killing Legion is still fun, and what would be the point if I didn't get my reward?
We also gain a new soul: the Gian Bat. Now we can finally fly through the air, but it's quite expensive.
