Eternal Sonata/Chapter 6: Tristesse

Baroque City
The merchant has some new merchandise so restock. Allegretto needs a Doom Guard, a Leaf Umbrella for Polka, Elven Sight for Viola, a Zweihander for Jazz, and a Illunis for March. The Muse Baton will lower your ATK and MAG but it will absorb 10% of inflicted damage as HP so itis something to consider. In armor, you will need a Freiturnier for Allegretto and Jazz, Land Scales for Beat and March, a Black Velvet for Polka and Salsa, and a Eagle Robe for Viola and Falsetto. The Honey Cookies are pretty handy too so if you have an Gold left you should buy a few.

Return to the castle for a cutscene in which you will acquire the Warp Room Key. Exit the castle.

The warp room is to the west of the castle. Use the key to enter Baroque City: Warp Room.

Go ahead and save, and then talk with the Guide. Step on the activated warp tile on the west of the save point. This will take you to Agogo Village.

Agogo Forest
Apparently, this section is for PS3 Versions only. Head south from your warp point to Agogo Forest: North. Don't worry about fighting enemies because they are at the same levels that you fought them last. All of the chests are empty too so don't worry about any of that stuff. Follow the path south to Agogo Forest: Middle North.

Again, continue south along the path. Save here and continue south to activate a cutscene and yes, another boss battle.

Fugue drops a Death's Hand.

Baroque Castle
Exit Baroque Castle: Guest Room and go to Crescendo's room in the blue door with the guard for a cutscene. Apparently, Crescendo is MIA. Go check Serenade's room on the other side of the castle in another blue door room. It will trigger another cutscene. Exit the room for a third cutscene. Serenade and Crescendo are both missing.

Exit the castle and return to the Baroque City: Warp Room. This time you will use the warp portal on the right to get to the next section after talking to the Guide.

To Coda Ruins
There is another warp portal to the northwest. Step on the portal to get to the top of a roof. Step on the next warp on the northern end of the buildings to get to the next section. Head to the next warp to the northeast. Now you are on a rooftop again and there is only one place to: the warp directly opposite your roof. So make your way over there to get to To Coda Ruins: False Pride Island.

Save your game.
