ゼルダの伝説：神々のトライフォース
The Legend of Zelda: Triforce of the Gods

With the Magical Hammer, Link can now reach most of Dark World. He can also reach a few new places in the Light World, including three more warp tiles (hidden under rocks), making it more convenient to reach various parts of the Dark World.

Using the Magical Mirror inside the Dark World counterpart of the graveyard near the church lets Link reach a previously inaccessible large gravestone. It moves aside when he dashes into it, revealing a secret room with a treasure chest at the end:

When Link uses the Magic Manteau, he vanishes (his shadow remains visible for reference). This lets him completely avoid damage and walk past certain barriers. However, it consumes his magic power rather quickly for as long as it remains active.

In a grove of trees in the Dark World near where Link's house would be, he finds someone who seems to have turned halfway into a tree.

Link warps to the Light World. A specter of the boy is briefly visible, then vanishes. After digging around, Link finds something blue.

Maybe they were afraid Americans wouldn't know what "ocarina" means. Of course, that's no problem since OoT came out...

Link warps back to the Dark World and shows the Ocarina to the boy.

Link plays the Ocarina, and the boy turns all the way into a tree. In Kakariko Village, Link finds a dozing old man and tries playing the Ocarina.

There's not much else Link can do here except play the Ocarina for the bird statue on the weather vane near the center of town. Amazingly, a strange bird bursts out of the statue and flies away when he does. From this point on, if Link plays the Ocarina again anywhere outdoors in the Light World, the bird swoops down, picks him up, and carries him to a choice of eight preset locations around Hyrule. This makes getting around much easier.

As long as Link's in the village, there's a cave by the smithy that he can now reach thanks to the Magical Hammer with a creepy shrine in the bottom. On a whim, Link sprinkles some Magical Powder on it, and a confused purple bat-like creature appears.

The bat-creature zaps Link with something that doesn't look very harmful, and a little 1/2 appears on top of his magic meter.

I can't tell whether it's saying that Link's magic capacity will decrease to half, or that his magic energy will decrease by half as much when used. It could be intentionally confusing, since the creature itself is quite confused to begin with.

Well, whatever the bat meant, and however confused it may be, what it actually did was make Link consume magic at only half the normal rate, meaning it lasts twice as long.

With the Ocarina, Link can easily travel to the cave in Mount Hebra where the old man he met earlier lives:

Atop the Light World mountain, Link can now follow the instructions on the tablet. He holds up the Master Sword. A bolt of bright blue energy streaks from the sky, engulfing Link, then forms into eight balls of cold that circle around him and then fly out in all directions. A large golden coin with a lightning bolt engraved on it falls from the sky.

Using the Ether magic eats up Link's magic meter (base cost of 32 magic for one use), but it can be worth it. When he uses it, Link quickly spins around three times, then holds his sword aloft. The same effect as described above happens, and it freezes or kills most enemies. It's similar to using the Ice Rod on everything nearby, though it uses more magic power, and oddly enough, the Ice Rod and the Ether magic don't always have the same effect on the same enemies.

In the mountains in the Dark World below the magic portal exit is a cave that Link can enter now thanks to the Magical Hammer. The ground inside is covered with spikes, so it's difficult to pass alive. Using the Magic Manteau, especially with half magic consumption, or recovery medicine or bottled faeries are all helpful. At the end is a treasure chest.

Much like the Magic Manteau, the Staff of Byra makes Link invulnerable, but drains his magic rather quickly. As an added bonus, it damages enemies that get too close (the same damage as Link's original sword) and knocks them away, though Link can't use his spin attack or the sword beams while the effect is active.

It's time to head for the next labyrinth, but first, using the Magical Mirror not far to the west of the dungeon lets Link reach another tablet on a high ledge in the Light World.

Link holds up the Master Sword. Flames spiral outward from where he stands, followed by explosions all around. A large golden coin with a spiral pattern engraved on it falls from the sky.

Using the Bombar magic eats up Link's magic meter (base cost of 32 magic for one use), but it can be worth it. When he uses it, Link quickly spins in place three times, holds his sword over his head, then touches it to the ground. The effect described above happens, setting nearby enemies on fire.

The ladder leading further in is too high to reach. Link can't go anywhere inside except to another telepathic tile:

The style is "old man" Japanese, so this is probably Sahasralah.

Link tries returning to the Light World. There's a similar structure in the same place, and inside is a lever that floods a channel corresponding to the one in the Dark World. When Link returns to the Dark World, he finds the channel there flooded as well, and can swim into the rest of the area.

This temple has a lot of water, several more flooding levers, bugs that skim the water's surface, and annoying waterballs that can only be permanently destroyed with the Ice Rod or Ether Magic. After some minor puzzles to reach the big key, Link can open the big chest:

The Hookshot, like the Boomerang, stuns many enemies and damages certain other ones (particularly useful against jellyfish and nearly everything else in this temple), but has no effect on others. Also like the boomerang, it will carry items to Link. The main use, though, is to hook onto various things—trees, stakes, skulls, statues, and so on—and pull Link over to them, even across pits. This lets Link travel deeper into the temple...

Crossing more wetness, a door behind a waterfall, and a flooded room with a strong current leads Link to the boss chamber. The opponent this time is a large one-eyed giant-jellyfish-demon kind of thing, with many little puffs swarming around it. Link can't hurt it, but using the Hookshot will pull off the puffs one at a time, and Link can kill them while they're separated from the main body. Once they're all dead, the demon-squid-thing goes ballistic, but it's also vulnerable now, and rather predictable. A few hits later and it goes down. Explosion, heart container, crystal. The second maiden is trapped inside.
