Phantasy Star II/Yellow Dam

After clearing the Red Dam, the next dam to target is the Yellow Dam. It is located on the west side of Mota. The easiest way to reach it is to teleport to Kueri, exit the town, and travel west until you find the jet scooter parked on the coast. Hop on and ride north until you see the entryway into the channel that leads to the entrance of the dam.

Yellow Dam
The Yellow Dam has a much more open floor plan than the Red Dam, although it gets much more sectioned off the higher you go. There are some incredible defensive items to collect on your way through here. Try not to miss any on your way to the control panel, which is located in the middle of the third floor.

Floor 1


Upon entering the first floor, use your Yellow Card to gain access to the interior. All of the chutes on the left side can be ignored, as they all lead to one dead-end or another. Instead, immediate cross over to the right side of the dam, and consider the two chutes that you find there. The top one will ultimately lead you to one of the great armors on the third floor, but serves no other purpose. The lower chute will get you going to your destination.

Floor 2


If you arrived here via the top right chute on the first floor, you'll need to travel far to the left to reach the chute that leads to the Crystanish armor on the third floor. That serves as excellent protection for Rudo.

When you arrive via the lower chute, you'll have an opportunity to grab an Escapipe from a nearby chest. A short distance away, you will find a chute that returns to the first floor. Once there, you will quickly find another chute that sends you back to the second floor. From there, you want to make your way to the upper left where you'll find the chute that gets you going in the right direction on the third floor.

Floor 3


There are a couple of chutes from the second floor that reach the third. You can pick up the Crystanish armor early on, but if you came through the chute near the upper left corner, your only choice is to take the chute below you to the fourth floor. While you're up on the fourth floor, you can return to the small chambers along the bottom of the third floor to pick up two more pieces of armor, the Crystcape for any of the ladies in your party, or the Crystchest for Rolf. Note that all of the Cryst armors can cast the GRA spell, which does a small amount of gravity damage to every enemy in battle.

Floor 4


You will first arrive on the fourth floor through the chute on the left side. Your goal is to get to the chute in the middle, and you can actually walk the whole way there by travelling along the bottom, to the right, up the right side, and back to the left before dropping down into the middle spiral.

However, on your way there, be sure to visit the chest at the top first and collect the Amber Robe. While this may seem like a mediocre defensive option for Hugh, its true value lies in its ability to be used as an item in battle that will cast GIRES and restore 60 HP (note that it can only heal the item holder, you can't select another member to receive this benefit.) It is one of a few such items that can be used in the manner, and it's a good idea to collect four of them so every party member can heal themselves in battle for free. For now, give it to your weakest party member to hold, like Amy, and have them use it whenever necessary.

Also be sure to hit the two chutes along the bottom of the floor, near the center, to collect the other two pieces of armor that you shouldn't miss before leaving the dam. Once you reach the chute in the middle, it will deposit you in the room on the third floor with the control panel. Use your Yellow Card on the panel to open the west dam and allow more flood water to escape to the sea.
