Phantasy Star II/Ikuto

The next building
The next building to take down is the one located closest to Zosa. To get there, start from Zosa, and head south. When the path opens up to the west, move in that direction. Before you reach the chute that leads back to Skure, walk north to find a small passage that leads West into the mountains. Once fully inside, continue north, and look for Ikuto in the north east corner.

Ikuto
Ikuto is one of the more difficult buildings in the second half of the game. It's construction is unlike any other dungeon in the game. Rather than using stairs or chutes to travel back and forth between floors, Ikuto is primarily composed of holes in the floor. Falling through these holes is how you travel through the building, and different holes can bring you to different regions of the dungeon. Since you are falling through holes, the trip is one way, you won't be able to backtrack at all.

There are six treasures to collect, and all of them are weapons. In order to collect each weapon, you'll have to fall through a different series of holes, so the correct path to each one will be provided below the maps. Eventually, you will follow enough holes to reach the bottom floor. From there, you must walk to the right side of the floor and locate the stairs that lead back up. However, at that point, it's far faster to use the Hinas spell, or an Escapipe.

Item collecting

 * Lac Dagger - Basement 2
 * Due to the bug that causes this weapon's stats to differ from the Japanese release, you can arguably skip collecting this weapon. If you want it, the path is as follows:  B → H 


 * Pulse Cannon - Basement 3
 * The Pulse Cannon is arguably a good weapon for Rudo, and to find one for free is great. But ultimately, you're here to collect Nei equipment, and one of the pieces of Nei equipment in Ikuto is the best weapon for Rudo in the whole game, so it's not necessary to go out of your way to collect this weapon too.  The path to it is:  A → F → U  or  A → K → Y 


 * Fire Staff - Basement 4
 * Yet another weapon you may want to worry about if you've held on to the Fire Staff that was available earlier in the game. The path to it is:  C → J → Z → M 


 * Laconian Mace - Basement 4
 * This is the strongest weapon in the game that Hugh and Kain can wield (although far from the strongest weapon in the game period.) To reach it, use:  A → K → V → L  or  A → F → S → L 


 * Nei Shot - Basement 5
 * This is the best ranged weapon in the game, and a huge offensive boost for Rudo. Take this path to collect it:  A → F → T → F → X .  Alternatively, you can take:  B → H → O → E → F .


 * Nei Slasher - Basement 5
 * This piece of Nei equipment is the best Slasher available for Anna to use. There are a few paths to reach it and they all involve a bit of walking.  A fairly short path to reach it is:  C → J → A → C → I .
