Magnet Hill

Go down the hole you found in the Fourside Museum and you'll find a magical river of poop.

It's pretty nasty down here.

There are a number of enemies that can do you in pretty easily if you're level is not high enough.

Keep your HP up with items and you'll be fine.

There are a few good items scattered through the sewers ( who the hell put them there... ). Make sure to snag those.

As you head west in the sewers you'll come to another shiny spot.

This is your fifth sanctuary.

Make sure you get your HP up before battle, this boss can be tough if you're not careful.

Per usual you'll want to throw all of your strongest attacks at this boss as soon as the battle starts.

I was able to use PSI Flash β on the boss and that made him start crying.

However, don't let your guard down because he hits hard.

Go up the ladder and you'll record the fifth melody on the Sound Stone.

Don't forget to get the Carrot key. You'll need that for the next section.

At first you might think you can just Teleport from here to the next area.

WRONG. You'll have to go back through the sewers first before you can Teleport. It's because it's a sanctuary.
