Zelda II - The Adventure of Link (Zelda 2) Walkthrough on Nes: Dungeon 5 - the sea palace
Map of the sea palace

As in level 1, the first statue does not have a red potion. This palace is a bit of a labyrinth and some corners do not need to be visited. I made over 5,000 experience points in this palace so you should normally gain a level before taking the crystal. Don't hesitate to leave some Mages alive.

Go down the first elevator and head to the right. Kill the ropes without slowing down too much (1) so that the dragon head statue doesn't hit you with its shots. Continue to the right and use the fairy magic at the bottom of the wall (2) to get to the next screen while avoiding the skull bubbles that take magic from you when you are in fairy form. Go back in Link form (3) to take the key and return to the right.

Cross the bridge, taking or not taking the 200 bag, and avoiding the dragon heads (1). Cross the next room by eliminating the red ironknucles (2) and any Bots that the statues might spit out. Go down the elevator and head to the left until you reach the place where the stones fall. Wait for a certain number of stones to fall in order to dig towards the key, always keeping a stone between you and the ceiling of the room (3), then take the key.

Go to the left, kill the orange ironknuckle and hit the dragon head statue to find a red potion (1). Go down the elevator at the end of the room after killing the ironknuckle and go to the left. Continue to the left to the next elevator, killing (2) or not the mages that fire flames. Go down one floor and go to the left to search for a 200 bag protected by a cyclops (3).

Go to the right without taking the elevator and use the "jump" magic to take the key after killing the ironknuckle (1). Continue to the right, killing or not the mages (2) and the blue ironknuckle, then cross the wall at the end of the room (3) by jumping into it.

Continue to the right without taking the elevator that goes down (1) and take the one that goes up at the end of the room. Go to the left, killing the blue stalfos (2), then take the key (3) at the end of the room. Return to the right and go back down the elevator.

Go to the left and this time, take the elevator. Open the door while watching out for wolf heads and mages. This passage is surely the hardest of the castle and you can use the "shield" magic (only if it leaves you enough magic to be able to cast "jump") to cross the room. If you use "shield", take the opportunity to kill the mages. In the next room, kill the ironknuckle to go to the left.

Kill the blue ironknuckle by opening the door and take the flute which will allow you to make the river demon south of Nabooru disappear. Retrace your steps without forgetting to take the red potion in the statue using "Jump". Cross the Wolfs-heads room (2), go up the elevator and go to the left once at the top (3).

Cross the wall again (1) and continue to the left to the elevator. Take it to go back up and go back to the left (2). Open the door, pass without killing the cyclops but potentially taking the red potion in the statue and go down the elevator. Cross the next room in speed, being careful of the mages and potentially taking the bag (3).

Cross the next room by killing the ironknuckles and take the key at the very end (1). Return to the right and go up one floor by the elevator. Go take the bag on the left protected by a red ironknuckle if needed (2), then take the elevator to go up one last time. Kill the orange ironknuckle, open the door then kill the blue ironknuckle by going to the right to arrive at the boss.

Gooma, the boss of this level has a bit of a cow's head but also the strength of a bull so beware. If possible, I advise you to use "Jump" and "Shield". Then, wait for it to make windmills and jump over its weapon flail then hit the stomach after having fallen back. If you have not used "Jump", stay at a distance until it strikes then move forward, hit the stomach and step back. Repeat the operation until the destruction of the big one.

The boss gives 500, you can seal the palace and continue the adventure (save).
