Here's mine.
My dungeon is a gigantic tower of twenty six floors, known as the Tower of Trials. It is mostly comprised of simple puzzles comprised of the themes of Forest, Fire, Water, Shadow, and Spirit, each ten floors taking a design cue from the various main temples in OoT and the last floor plays a melody of all the remixed tunes from the past twenty five floors while making a new environment as though you are in a stone tower. In order to progress, you must defeat all the enemies and solve the puzzle.
Floors 1-5
These floors consist of a Forest Temple like design, containing a remix of the Forest Temple theme from OoT. They have various forest enemies which are Deku Babas, Deku Scrubs, Giant Deku Babas, regular Keese, Spear Moblins, and Bokoblins.
In Floor 1 consists of 10 Deku Babas and a jet stream that activates when you defeat all the babas. The wind puzzle requires you to fire bomb arrows into a horizontal jetstream over a pit with a switch at the end. If you fire it directly into the jetstream, it follows it and should hit the switch, opening a staircase and allowing you to progress.
Floor 2 consists of 5 Deku Scrubs and when you defeat them all, a grating along the ceiling will open and a hookshot target will be accessable. This puzzle requires you to hook onto the target, and as you're falling, use the sword to hit a nearby switch, allowing you to progress.
Floor 3 will consist of 7 Giant Deku Babas and when you defeat them all, the room angle will twist and a hole on the ceiling will now be a pit into the next floor.
Floor 4 consists of 30 Keese and 4 Deku Babas. When they're all dead, 5 Green Bubbles and 5 Blue Bubbles will appear. After those are dead, Bokoblins, Skulwaltulas, Skultulas, and Gold Skultulas will appear. Finally, after that wave of enemies is dead, a boulder will squeeze it's way through the hole you were just in and follow you. You must lead this boulder to the western wall and quickly get out of it's way when it gets close. If done right, it will smack into the wall and reveal a hidden alcove with a switch. Smack it with your sword and it flips the tower again, revealing a staircase that you couldn't accesse before. Going up it will result in the final floor of the Forest Temple theme.
Area Boss: Phantom Ganon X
Floor 5 contains an exact replica, in all it's 64bit goodness, of the Boss Chamber of the Forest Temple in OoT complete with a near exact replica fight with Phantom Ganon. This time however, he is Phantom Ganon X and is much more powerful and much faster. The concept of the fight remains exactly the same as in OoT, but Phantom Ganon X causes a full two hearts more damage on each attack than he did before. He is also more competent when it comes to Zelda Tennis, and will take a couple more volleys for him to slip up. Defeat him and he will explode, leaving behind a Heart Piece and a portal. Go into it and you'll get your health, magic, and ammo replenished and find yourself in the next set of rooms.
Floors 6-10
Floors 6-10 are Fire Temple based floor and have Fire Toadpolis, Keese, Fire Keese, Wizzrobes, Red Bubbles, Ache Men, and Dodongoes.
Floor 6 consists of three Dodongoes, 10 Keese, a circular platform in the middle, and a lava pit all around the platform. When they're all dead, a staircase will rise from the lava next to the platform, giving Link access to the next floor.
Floor 7 consists of a circular platform, a lava pit, 5 Fire Keese and three Ache Men. After they're dead, a boulder will come out of the lava and chase Link. Link must bomb the boulder in order to blow it up and a crystal switch will appear. However, four Wizzrobes will pop in and summon it to where they came from. These Wizzrobes will summon other Wizzrobes that have the ability to summon monsters and they will all summon Keese, Dodongoes, Darknuts, and Fire Toadpolis. After they're all dead, the switch will respawn allowing Link to smack it with his sword and a staricase will rise from the lava, allowing Link to progress.
Floor 8 will consist of a few small circular platforms, a lava pit, 10 Fire Keese, 15 Red Bubbles, and a Dodongo. When they're dead, a staircase will rise from the lava, giving Link access to the next floor.
Area Miniboss: King Dodongo
Floor 9 has 15 Keese, 15 Fires Keese, 5 Red Bubbles, and 3 Dodongoes. When they're all dead, a gigantic Dodongo will appear. He is the same as a normal Dodongo in the sense that he will just whip his tail at you and breathe fire at you, but he requires bombs to defeat. When he sucks in air, Link will be slowly sucked in with all that air and he must throw a bomb into it's mouth. Should he fail and get sucked in, he'll be crunched and chewed and then spit out, along with a ton of fire which, in total, will do 5 Hearts of damage. Should he succeed and throw the bomb into it's mouth, it will explode inside the creature, stunning it, and allowing Link to slash at it's only weak spot: the head. When that's done, a staircase will rise from the lava and allow Link access to the final Fire Temple floor.
Area Boss: Volvagia X
Floor 10 is an exact replica (in every detail) of the Boss Chamber from the Fire Temple in OoT. And the boss, is a powered up version of Volvagia, known as Volvagia X. Alike the last Area Boss, Phantom Ganon X, the fight with Volvagia X is the same in concept, but Volvagia X is more powerful and faster. All his attacks however, do a whopping three hearts more damage than the original boss. When he's defeated, he'll explode to leave behind a Heart Piece and a portal that restores Link's health, Magic, and ammo.
Floors 11-15 are based off the Water Temple and contain a remix of the original Water Temple theme from OoT. The enemies consist of Water Toadpolis, Blue Tektites, Land Octos, Ocean Octorocks, Big Octos, and Cheep Cheeps.
Floor 11 consists of a room with a body of water and a platform on the south end. There are 4 Cheep Cheeps in the water and they are impervious to every single weapon Link has... from the outside that is. However, bombs will not work because the fuses will be put out once they hit the water, and the Cheep Cheeps don't come out of the water. So Link must purposefully get eaten by the Cheep Cheeps and slash his sword within 3 seconds to kill them, or it's game over for Link. When they're all dead, a jetstream of water will come rushing up and Link must get into it and be propelled up into the next room.
Floor 12 consists of a platforms in all the corners of the room, 3 Cheep Cheeps, and 5 Water Toadpolis. When they're all dead, four gigantic bombs will fall onto each of the platforms. They each have fuses that stay lit for three seconds, and they will explode, giving Link a game over... that is, if he's not underwater. Link must dive to survive the explosions and when they're done and over with, four alcoves will be revealed in each of the four corners and a chunk of the ceiling will break off and fall into the water, plugging the jetstream that brought him to Floor 12. Link must stand atop this chunk of the ceiling and fire arrows at all of the switches within the four newly exposed alcoves. If Link does it within 10 seconds, then the jetstream will become more powerful and propel the chunk of the ceiling, as well as Link, into Floor 13.
Floor 13 consists of a small room with 10 Blue Tektites and a pool of water. When Link kills them, another big bomb will drop down onto the platform, and give Link 3 seconds to dive. When the bomb goes off, the chunk of ceiling will be blown up and the jetstream will continue into the 14th floor.
Floor 14 consists of the jetstream hitting the ceiling and a staircase blocked by a grate, 20 Keese, 20 Ice Keese, ten Land Octos, and five Octorocks (the ones that are in water).
Area Mini Boss: Dark Link
When they're defeated, the room will morph and twist into a gigantic expanse with a small puddle all across it and a small, dead tree in the center on a small sandy island. At that island is Dark Link, whoknows single sword technique Link knows. To make things worse, he'll zap Link, which will make him drop his weapons, which Dark Link will promptly collect while Link is stunned. Then the battle begins. To begin with, Dark Link will not only block all of Link's sword swings, but also dodge and parry them, ala Wind Waker. Dark Link will use the Hookshot to pull Link to him and will promptly slash him with his sword. If the Hookshot hits the shield, it will pull Link close to Dark Link and if it hits Link himself, he'll lose a half heart. He'll also shoot arrows at you and if they hit Link, they'll do 2 Hearts of damage. And his biggest weakness if when he uses bombs. When Dark Link throws bombs at Link, he must pick them up and throw them back at Dark Link, at which point they'll explode and stun Dark Link. Then, Link must slash at Dark Link and repeat seven times until he's dead, and then Link will recollect his items automatically, followed by a warp portal opening to refill Link's Magic, Hearts, and ammo.
Area Boss: Morpha X
Floor 15 is an exact replica of the Boss Chamber from the Water Temple in OoT with the very same boss, albeit powered up and under the suffix of "X". Morpha X does a total of 4 Hearts more damage than the original boss on all his attacks while being faster and able to take more hits. He also gets extra arms, a total of four near the end, and there isn't a corner for you to hide at because you can only fight on one of the five platforms. When he's defeated, he'll explode to leave behind a Heart Piece and a portal that will warp Link to the next area as well as restore his Hearts, Magic, and ammo.
There'll be more to come later, but for now I've got to get to bed.
