Entry Cavern
You land in the same entry cavern as before, but in a different area. Leap across the short gap, and grab the Rupees on the nearby ledge.
You seem to have reached a dead end, but looks can be deceiving. Use the Lens of Truth to spy a door beyond a false wall to the west, and go through to reach the next room.
Path of Hidden Foes
Beware: the next passage is filled with invisible Bad Bats and Skulltulas. Continue using the Lens of Truth to spot them, then lock on and use the Hookshot to safely defeat each threat from range. (The Skulltulas are the real troublemakers.)
Smash the jars at the end of the path, then notice that one of the walls is slightly cracked. Use a bomb or the Blast Mask to obliterate the wall, revealing a door that leads to the next chamber.
Iron Knuckle Chamber 2
Oh no, it’s another Iron Knuckle! Like the last one you faced down here, this formidable warrior won’t engage you until you strike it. Prepare for battle, and then shoot the Iron Knuckle with an arrow from afar. Stay evasive, make the monster miss, and then quickly strike it once with Link’s blade. Keep dodging and countering, and remember that the Iron Knuckle becomes faster and more dangerous after it loses its armor.
After you slay the Iron Knuckle, a chest appears in the center of the room. Open it to claim a worthy reward: a Piece of Heart.
Piece of Heart #31
You got a Piece of Heart! Collect four Pieces of Heart to assemble a new Heart Container. Each new container you put together increases the amount of life energy you can have.
Familiar Deed
You’re all done with the Ikana Graveyard for now, and you’re ready to soon head back to the coast. But before you soar there, soar to Clock Town. You’ll be needing the Mountain Title Deed, so follow these steps to reclaim it:
Go to the observatory, look through the telescope, and spy on the Skull Kid atop the Clock Tower to make the Moon’s Tear fall.
Collect the Moon’s Tear, soar back to Clock Town, and give it to the Business Scrub in exchange for the Town Title Deed.
Soar to the Southern Swamp, and speak to the Business Scrub near the Swamp Tourist Center as normal Link. Trade him the Town Title Deed for the Swamp Title Deed.
Soar to Mountain Village and go east into Goron Village. Speak to the Business Scrub in the Deku Flower down south as Deku Link, and trade him the Swamp Title Deed for the Mountain Title Deed.
When the Mountain Title Deed is finally in your possession, soar to the Great Bay Coast and swim to shore. Sprint through the south tunnel to revisit Zora Cape.
