Zelda II - The Adventure of Link (Zelda 2) Walkthrough on Nes: Dungeon 4 - Maze Island Palace
Maze Island Palace map

First, go down the elevator and head to the right. Kill the 2 Stalfos in blue armor (1) after they come out of their hole (I recommend low attacks), take the bag and continue to the right. Go down with the elevator and take the first path to the right. Kill the Stalfos (2) and continue to the right. Go to the end of the collapsing bridge and jump (3) to solid ground (you can ensure your jump using the "jump" magic).

Continue towards the right while eliminating or jumping over the Doomknocker (1). Then, jump from platform to platform and break the blocks to jump without problems over the flames. Go to the end of the path and take the key (and the red vial in the statue (3) if needed). A Doomknocker can block your way on the way there or back (for me, it fell into the lava both times ^^), in that case, kill it as it could make you fall.

Come back to the left and fall into the hole. You land on a collapsing bridge. If you took the key above, go quickly to the right (1) (otherwise, you will have to make a free lap). Kill the Doomknocker then the Stalfos and continue towards the right.

Kill the blue Ironknuckle while opening the door and take the boots that will allow you to walk on water. Retrace your steps, fall into the hole and leave quickly to the right. Go and take the key completely to the right by killing the enemies so they don't push you into the lava.

Come back to the left and open the door. In this room, use Reflect and crouch down while watching the ghosts (1) (Wizzrobes) that appear to kill them by deflecting their attacks (you must be relatively close to them). Continue to the left without taking the elevator (2). Go to the end of the room to take the key (3), dig to the left, climb back onto the blocks and return to the elevator (I advise you to dig the left blocks before going to take the key. To climb back up, use jump if necessary). Note that one of the blocks contains a red potion or an Ironknuckle (just to the left of the first "hole" in the blocks).

Take the elevator and climb all the way up (1). Head to the left to the first room. Use "reflect" to kill the Wizzrobes (2), open the door and continue to the left. Kill the Ironknuckle then break 2 blocks above you (3). Wait for the skull bubble to reach you to kill it then use the "jump" magic to go and get the key.

Continue to the left without taking the elevator. Kill the Doomknocker, and go to the next room. If you have health points and need experience, climb up, kill the Doomknocker, and dig down to take the key then to the right to exit the room by taking the bag. If you have low health, dig to the left up to the key as soon as you arrive in the room. Return to the right to the elevator, go down and go to the right. Kill the dragon heads by stopping far from the edge so as not to fall, you can use shield and jump because a red potion awaits you.

Go to the end of the room and take the key and the potion in the statue. Retrace your steps to the elevator room. There, use Reflect to kill the Wizzrobes and cross the room to the left. You arrive in a room with collapsing bridges and Myus on them. This passage is quite "hot" because if one of the Myus is on the edge of the bridge, it is not easy to jump over it without falling back into the lava. To not take risks, equip "fairy" and use this magic if it goes wrong. In any case, go down the elevator on the left of the room.

Go to the right, kill the Stalfos, take the bag using "jump" (if you have enough left to do the "reflect" magic and the "shield" magic after) and continue to the right. Kill the red Ironknuckles while crossing the next room to arrive in the boss room.

As always, use the shield magic before going to face him. Carock is actually just a big, very fast Wizzrobe but quite easy to beat. To beat him, use the "reflect" magic, stand on one of the 2 sides of the screen and crouch down while watching the middle of the room. You just have to wait for the boss to die. However, if he touches you by appearing on you, you will have to get back into position.

The boss yields 300, you can seal the palace and continue the adventure (save).
