I didn't see a leaderboard category for this so I went ahead and made a route for this particular speedrun:

Here's an official run before certain changes were applied to Group 4 and Boss Fight strats. RTA time is 2:08:42; In-game time is 1:50:05.

Splits have since been updated to include boss fights but idk how to share it lol. Please share any strategies that may enhance this particular category's efficiency. Thanks!
