    At the Waterway Entrance, South - B1, head north to find a Potion and a Maiden's Kiss. Backtrack to the entrance, go west across the bridge, and south to find a Tent. Head north across the bridge and talk to the Old Man to recruit Sage Tellah.

    Tellah defaults to the back row; equip a Leather Cap on him if you have one.

    From Tellah's location, head north to the next floor. Alternatively, cross the bridge east, descend into the water, go up the waterfall for an Ether, then descend and head west to a wide waterfall. Enter the left side to find an X-Potion, a Dry Ether, and a Phoenix Down. Return to where you met Tellah and head north to the next floor.

  6. 6
    Head south, descend into the water, go slightly east, and up into a door to the next floor.
  7. 7

  8. 8
    At Underground Waterway, North - B2, head north for a Potion. Continue north but stop south of the steps. Go west into the wall and follow the path to find a Feathered Cap. Backtrack and enter the next area.
  9. 9
    At Waterway Entrance, North - B1, head north and take west stairs up for an Ether and a Zeus's Wrath. Backtrack, cross the bridge, and head south to find the Shadowblade (equip on Cecil immediately). Enter the next area.

    You will reappear on the Overworld. Use a Tent and Save if needed. Proceed to the northern cavern.
  11. 11
    At Underground Falls, proceed downwards.
  12. 12
    At Underground Lake - B2, follow the path to steps going down. Pick up the Hades Helm and Hades Glove (equip on Cecil). Go back up and continue around into a door.
