After meeting Melari on Mt. Crenel, you continue on to the second dungeon, the Cave of Flames.

Get the Compass

Go through the east door. If you hit the Bob-ombs with your sword, they will bounce around the room and explode, but you can use your Gust Jar on them to prevent that, or, if you bought the Boomerang from Stockwell in Hyrule Town (which becomes available after you buy the bigger wallet), you can hit them with it to defeat them instantly, but keep your distance to avoid the explosion. In this room, bomb the north wall and go through.

Equip your shield and hold the shield button to raise it, and if a Spiked Beetle hits you when your shield is raised, it will flip over and become vulnerable to sword attacks. After you defeat the Spiked Beetles, a chest appears. Open it to get the Compass, then go through the west door.

Get the Map

Don't pick up the rupees: one of them is a Like Like in disguise. If the Like Like catches you, you could lose your shield—but you can buy another from Stockwell in Hyrule Town if this happens. If you have the boomerang, you can collect the real rupees and reveal the Like Like from a safe distance. Otherwise, you can hit the rupees with your sword to reveal the Like Like from a slightly less safe distance. Kill or ignore the Like Like and go north down the stairs.

Go west and follow the path until it splits. Go east at the split, then push on the mine cart at the end of the track. You will automatically get into the cart and ride along the track. At the other end, go west until you find a weird-looking wall. Use a bomb on it and go through.

Use the Gust Jar to remove the monsters' helmets, then defeat them. A shrinking portal will appear. Use it and go through the small hole in the northeast part of the wall. Keep going east through the doors, and go east through another small hole. There is a Piece of Heart that you can't get yet, and a small hole in the south wall. Go south through the small hole, then go south through another small hole to reach the next room.

Go west, then south to a small gap in the barrier. Jump down from there, and go east, making sure not to touch the flames. Use the shrinking portal to grow to normal size. Go up the stairs to the upper part of the room and open the chest to get the map.

Get a Kinstone Piece

Go south onto the platforms floating in the lava, but make sure not to stand on the platforms too long or they will crumble and you will fall into the lava. Go west to the treasure chest and open it to get a blue Kinstone Piece.

Get Rupees

Go south from the chest and step on the switch to open the door. Go east on the floating platforms, then south, but don't stand on the floating platform next to the pots. Stand on solid ground and use the Gust Jar to remove the pots that are blocking the path. Then go east to where the pots were, and follow the path to the door that you opened. Go through.

Get on the floating platform, then quickly step off before the platform crumbles beneath you. Hit a Rollobite to make it roll into a ball, then pick it up and throw it into the hole just south of the treasure chest to the north. Open the chest to get 50 rupees.

Get a Key

Hit another Rollobite and throw it into the northernmost hole so you can walk on it and pick up the pots. Go north up the stairs. Then jump into the whirlwind and go south, and float into the whirlwind that you see there. Then go east, then north to solid ground. You can press R to stop floating. Go north up the stairs, then go to the northeast corner and step on the switch. Then go to the rightmost block and push it upward. Then push the pillar with the chest on it to the west until it falls into the hole. Open it to get a small key.

Get a Piece of Heart

If the door to the north of the chest is closed, go to the northeast corner and step on the switch, then go through the door.

Go east and get into the mine cart. At the end, unlock the nearby door and go through. Walk along the tracks to reach a lever. Hit the lever with your sword to change the tracks. Then go back to the mine cart and get into it. You will reach a new area.

Go west, then north to the next room. Fall into the hole and wait for the blade traps to move out of the way, then go north. Walk east on the tracks, then lift the pots to the south and bomb the wall there. Go through and take the Piece of Heart, then go north to the previous room. Then go north to the next room.

Get the Cane of Pacci

Go north to where you can jump down from the ledge, and jump down. Go west and some Spiny Chuchus will appear. You can't hurt them when they are spiky, but you can throw bombs at them. Or you can wait for their spikes to go away, then hit them. After they're gone, open the chest to get the Cane of Pacci. It flips objects over. If you use it on a hole, then jump into the hole, you will be launched upward.

Go west to the next room.

Get a Second Key

Stand on the first lava platform, then quickly use the Cane of Pacci on the second platform to flip it over so you can walk across it. Go west and then south to approach the hole in the floor. Ezlo says to use the Cane of Pacci on the hole, so do that, and there will be spinning energy there. Jump into the hole and you will be launched upward in the direction you were facing. Do this to reach the ledge to the south. Step on the floor switch to create a warp tile and open the door. Go south through the door.

Use the Cane of Pacci on the mine cart to flip it over. Go into the mine cart. At the end, push the pillar with the chest on it into the hole, and open the chest to get a small key.

Ride the cart back to where you came from, and go back to the room to the north. Drop down below and use the key on the door above. Head down the stairs.

To the right is a shrinking portal, use it and carefully get past the traps. If you're walking you can hit R to roll, which gets you out of the trap's way faster. Go through the small hole. Go through the maze area to reach a shrinking portal, use it to grow to normal size. Now, when you go back through the maze, the small red things will activate and move down the path, hurting you if you're in the way. Move quickly and move to the side to keep out of harm's way. Once out of the maze, flip over the mine cart and get in. At the other end, flip the switch to change the tracks and get back in the cart to get to a new area.

DON'T put one of the worms into the hole at the top left. You need all four worms to go into the four holes at the bottom right of the screen so you can pull the pillar with the switch on it, and push it into the top left hole. Once it's in there, hit it and the path will open. Continue on.

In the next area, drop off from the north end of the ledge, open the chest (blue Kinstone piece) and push the top block out of the way. Go a little south and you see a hole, use the Cane of Pacci to power it up, and jump in to get to the ledge with the chest (green Kinstone piece). Exit right.

Slash the flames out of the way, then get in a position so the first lava platform is not in your way and you have a clear shot to the spiky one. When the spiky one passes, flip it with the cane. You want to ride the platform UP not down, so wait until it's coming up from below to get onto it. Get off at the upper right (below where the big door is). Step on the switch here to create a red warp. Next, go back left, use the Cane of Pacci on the spiky platform again, and head left across the platforms to reach the start area.

Flip over the spiky platform a third time, and this time, ride the second platform down. Quickly flip the platform below to get on, and do the same for the one to the right. Get off at the other end. Go up, and before moving on, use the cane to flip all the pots to the right to get them out of the way. Then flip the moving platform above you, hop on, then get off onto the safe area below. Flip the other platform above, and get on. You have some platforms to flip, so don't waste time and flip them as soon as you can. Make your way to the right, and at the other end exit to the next area.

Go up the stairs and drop down into the hole. If you want a green Kinstone piece head right first. Carefully avoid the traps to reach the chest with the piece inside. Avoid them again to exit left. Use the cane on the top hole to boost yourself up to the ledge, and drop down the other side. Use the cane on this hole, and get in and face the tornado so you float up to the ledge above. Take the path right to the next room.

At the end you reach another tornado, and if you look on the floor below there's a path of tiles. Follow that path as you float to get to the other ledge. Once you reach the lava room, you have a lot of tornadoes to navigate through. Avoiding the stalagmites, use the one at the starting ledge and head south to a safe spot. There's another tornado here, and before moving on you may want to use it (using the cane to reach it) to get to the chest on the ledge above, it contains 100 rupees. Next use that tornado to float slightly northwest to the spot with the flames and the hole. Use the cane here to get to the ledge above. Next is another tornado, use it to go in a general west direction, using tornadoes on the way to keep going. Stop at the platform to the lower left with the chest on it and grab the green Kinstone piece. Then use the cane to reach the next tornado, and go into the next tornado northeast to reach the ledge with a big chest on it (big key). Drop off the platform to the north (left of the chest). Slash the flames for recovery hearts if you need to. Flip over the moving platform to the left, then as it's going up, take it up to the boss door.

Gleerok

To get to the boss room you have to drop down the hole. First use any pots to recover hearts if necessary.

Gleerok will spit flames, but they can be cut with your sword, and sometimes hold recovery hearts. You need to circle the lava pit so you're around the side of Gleerok (you should roll to move faster) to use the Cane of Pacci on its shell. When you hit it and it's stunned, run across its neck and hit the spot on its back repeatedly. When Gleerok starts to sink, quickly run back across its neck so you don't fall in the lava, and stay near the wall, as the lava will spread outward. Be careful not to get hit by any falling stones. Stay out of the way of Gleerok's mouth, it will do a big flame attack (you can still cut down the flames). Repeat until Gleerok is beat.

The heart container and warp tile are above.

Continue On

After this dungeon, you should infuse the Picori Blade with the two elements that you obtained.
