After defeating the 1st boss Lineback tells you to go to Mercay Island then go to the Ocean King Temple there Oshus will tell you about the phantom hourglass. U get the hourglass and u can go father in the temple. there is a door you will need the first spirit to open it. I think you can take it from there ya but how do do you get past the second floor B2?
In the temple of the ocean king.
The Temple of the Ocean King is located on Mercay Island, in the north.
when you get your sward go to the north kill the monsters, go through the cave, and you are there!
Actually you go to Ushus on Mercay Island instead of the Temple of the Ocean King. Then you hunt down the ghost ship after a little cutscene.
You need to first have all the Spirits of the Ocean King and the Phantom Sword. Then, just go through the Temple of the Ocean King down to the last floor where Bellum is.
You get the last sea chart in the Temple of the Ocean King, B12. You get the last sea chart in the Temple of the Ocean King, B12.
