Golden Sun/Crossbone Isle

Crossbone Isle is an optional and secret dungeon-style location in Golden Sun and is easily viewable as that game's primary "super-dungeon", much like how many Role-Playing Games feature one or more dungeons more challenging than the normal "final dungeon" that game features. It is filled with powerful and unique enemies and equipment within its ordered series of ten floors of puzzles, and is most notable for having the most powerful monster in the game that aspiring players can fight, Deadbeard.

Getting there
There are two ways to reach Crossbone Isle. The first way to get there is by event on the Tolbi Bound Ship. You must select passengers in a certain order in order to get there. If you want to get there via this method, you wouldn't get very far due to your party members lacking certain psyenergy to bypass certain areas. The other way to enter Crossbone Isle is riding the pinkish Tornado in Suhalla Desert. The Pink Tornado is reachable by entering the cave behind Flash, the Mars Djinni. To those who do not know how to reach the djinni, enter the second map in Suhalla Desert and travel on until you come across a area where you climb down into the desert sand (right before fighting the Storm Lizard boss). DO NOT climb down, instead head left and use reveal to reveal a hidden log and some shining footprints. Follow the footprints and you'll find Flash. Enter the cave before you and follow the path to find the Pink Tornado, enter it but do not use douse, instead let it carry you and you'll be transported to the world map on a remote island. If you do happen to use Douse on the pink Tornado, you'll end up fighting the Tempest Lizard.

So kill or ignore Tempest Lizard if you want here, if you do happen to kill it though, the tornado will disappear and you'll be trapped on the island FOREVER!!! Just Kidding. To make the tornado reappear, enter the centre of the island and exit back to the world map and it'd be back.

Outside
Now, to begin with, the dungeon entrance is located on the centre of the island, enter there and there should be a cliff. Use 'Growth' (get this by giving a mars djinni to Isaac or a Venus Djinni to Garet) on the vines. Ignore the nearby whilwindable bushes and continue climbing up. At the top there should be a tree with a Nut acquirable with catch and three slides, the one on the far right will take you to a chest containing a mint, the centre will take you to a chest with 1 coin and the one on the far left will take you to the enclosed ground with a bush. Use whirlwind and the entrance to Crossbone Isle is revealed.

Basement 1
When you enter, go downstairs and there you should arrive at a floor where there's a big gap and a pillar on the other side. Ignore that for now and prepare yourself for a battle before entering the door:

Room Puzzle
After defeating the Gryphons, you'll enter into a dark room. To those who arrived by the Tolbi Bound ship, I'm afraid that this is the furthest you can go as you are lacking the Cloak Psyenergy (unless you somehow hacked the Cloak Ball of course), however if you do have 'Halt' you can reach 1 chest containing a measly Sleep Bomb. If you do happen to have the Cloak psyenergy, you can bypass the statue in the darkness, simply stay in the shadows and sneak past the statue. However if you do happen to come across a statue in the lighted area (where you cannot cloak), use 'Halt' on it and it will freeze allowing you to bypass it. There are 4 chests in the room containing a Sleep bomb, Smoke bomb, a Psy Crystal and a Storm Gear. The chest containing the Storm Gear is on the top right corner of the map. Once you've done with this room, exit via the right, push the pillar on the right once again and head down another floor.

Room Puzzle
Once you've taken care of the guardians, you'll find yourself in a room similar to the Kolima Forests Floodgate Puzzle. There are 4 chests in this room each containing 555 coins, a Potion, a Lucky Medal and a Ninja Garb, a moderately defensive armor with a huge agility boost and some Jupiter resistance. The chest containing the Ninja Garb is located in a spot enclosed by rocks.

Getting the Ninja Garb: There are six logs in the area, but two of them are permanently fastened in place, so only the four logs between them are to be moved. There are essentially two horizontal logs rollable up-and-down and two vertical logs rollable left-and-right. First, head counter-clockwise around the room's perimeter to a chest with 555 coins. Then go down to where the rolling logs are. To get to the lower left-most chest, roll the lower vertocal log left, then roll the left horizonal log down, then the right horizontal log down, then the lower horizontal log right, and finally the right horizontal log back up, creating an effective path to one particular chest that will be traversable once the floodgate switch at the elevated bottom of the room is flipped. The chest contains the Ninja Garb. If you're confused with the description above, the image on the right might help you.

Once you're done here, exit this room and once again, push the pillar on your right and head down.

Room Puzzle
This room is one giant Puzzle, there are four chests in this room along with one Venus Djinni. First up, move the two pillars in front of you so you can create a path. Next head upwards and move the pillar with the chest so it enters the wall gap. Now go back to the area with the two pillars and climb up one level and jump across the pillars to reach the chest containing an Elixir. Continue following the path until you reach the Venus Djinni which would hop down one level to avoid you. Continue along the edge of the wall until you reach a single pillar, push it down a level. CLimb to the bottom floor and freeze the puddle, jump across to reach a chest cointaining 666 coins. Continue along your path and you'll reach the Djinni and he'll jump up a level and run to the right. Push the pillar ahead down and move it until the big ladder is blocked. Climb up two floors and climb down the now blocked ladder onto the pillar and hop right to obtain the chest containing the cursed Demon Axe. Follow the Djinni once again and he'll run again once more. Follow the path until you see the Djinni nearby the three block obstacles. Unless you want to play an endless game of tag with the Djinni, use Halt on it and you can finally nab it. Once you grabbed the Djinni Bane, head to the left side of the room to where the frozen pillar is, move the pillar to the right side of the frost puddle but make sure you're on the upper area before moving the pillar. Now climb up a floor and move down to the pillar and hop your way to the centre of the room to obtain the chest containing the Water of Life. After you got all the items, you may exit from this room. Remember to push the pillar on the right before moving downstairs.

Room Puzzle
This room cannot be passable if the Player does not have the Psyenergy 'Carry'. This room may be a bit confusing at first but it's actually pretty easy.

First, run up over to where the stone cube that one can normally Carry is on the ground level in the general vicinity of three independent chests. Push it two spaces right and one space up, and use Carry to place it one space up beyond that. This lets you get the upper right chest which has a Lucky Medal. Exit and reenter the room so that the cube is reset in its original position. Now push it left two spaces and Carry it over left one space, then get over to where the cube now is by climbing up and down ladders and use Move to move the cube three spaces left so it falls off the other side of the elevated portion. Move it one space left more and one space down, and it will now construct a hoppable path to the chest in the bottom of the general vicinity. This chest contains the Wicked Mace, perhaps the best of the cursed weapons found at Crossbone Isle. As for the chest in the top central area of the vicinity, move the cube back up and right, Carry it onto the elevated portion right, and from there move it two spaces right and one space up, and Carry it one space up so that it allows Isaac to hop onto the cube to grab the chest in front of him, containing a Psy Crystal.

With the top three chests collected, head downward in the direction of the room's exit. A second Carry cube is there, and it is to be pushed down two spaces and left five spaces (don't push it more than that as it will fall into the pit), and then Carried over up one space. This bridges an elevated gap and allows you to head toward the exit. But you will notice an unopened chest to your right. While the bottom wall obscures the platform it is on somewhat, you can easily hop to an empty space in front of the chest and claim 777 coins before leaving for the exit.

Room Puzzle
The puzzle room behind it is similar to floor 6 in that it is one giant puzzle that can be fully completed through a single specific linear path of progression. First, hop upward over the puddle and cast Frost on it, and use to cross into the top central area where there are two chests bordering each other. Opening the top chest obtains 888 coins, then slide down the nearby slide, go to where the two logs are bordering each other, and push a rock on the ground two spaces right. While you could exit at this point, the loot in this room is extremely useful, so continue by hopping over the left puddle and casting Frost on that as well, and that will allow you to the leftmost chest with a Potion inside it. Hop back right to where the dragon statue is, slide down, and cast Frost on the puddle underneath the white tile. The dragon statue will blow steam to melt the first frost pillar you froze while the tile on the third frost pillar rises up to allow access to the chest to the right of the statue, which contains a Smoke Bomb. Then roll the lower horizontal log downward one space. Hop back over the first puddle and cast Frost on it again to make it a pillar again, and make your way to the ground level of the left half of the room, and push the upper horizontal log downward one space. You will finally access the chest above the ladder, which contains the Cleric's Ring, a very important piece of equipment that allows one Adept to safely equip cursed items. Exit the room afterwards, push the pillar down outside and climb down.

In the last puzzle room of Crossbone Isle, roll the immediately visible left horizontal log up, roll the vertical log you arrive at right. Go down to where the lower right horizontal log is and roll it up, hop over to one of the two adjacent vertical logs and roll it left one space, hop down to the central vertical log below and roll that right, and rolling the lower right vertical log left will allow access to the small island with a chest containing 999 coins. Roll that log back right, roll the central vertical log left, and roll the above horizontal log up to be able to hop onto the area where there is a chest with a Sleep Bomb. Roll that log back down and arrive at the chest in the center of the room and the two lakes, the chest containing a Water of Life.

The second lake in this room has three horizontal logs neatly arranged along its bottom perimeter and three vertical logs arranged along its right perimeter. To reach the chest far up, roll up each of the horizontal logs on the bottom perimeter. Then roll the lower vertical log left, roll the central horizontal log down, roll the central vertical log left, roll the right horizontal log down, and roll the upper vertical log left one space. The chest contains the cursed sword Muramasa, and whether this weapon is better than the Wicked Mace or not depends on the player's taste.

STRATEGY

(done at all level 24)

The easiest strategy is to have all djinn and have them set before the battle begins. once it starts summon all level 4 summons. The first turn he may use freeze prism and reduce most of your party to half or a little less then half HP. This is ok, just follow up with level 3 summons. one of your party members (most likely Ivan) may die on the second round so bringing water of life will help. By the time all the level 3 summons are finished Deadbeard should have felled. And after the battle, you can get the Demon Mail from the chest
