Table of contents
Inside the Ancient Cistern, walk toward the locked door in the middle of the giant room. To the right of the door, read the tablet. You’ll learn that the inscriptions of gratitude you’ll need are in a secret order and located on the back, rear, right hand, and left hand of the Great Statue.
Hop into the water and swim to the back of the Great Statue. You’ll find the first symbol just above the waterline. Note the direction of the blue petal? lobe? — top.
Swim down to the bottom, and look under the arch for the next symbol — it’s directly below the first. This one shows the bottom.
Swim back to the front of the Great Statue. Its right hand is on the left (west) of the map. Spin to dash across its palm and collect the silver rupee there. The next symbol is on the hand’s knuckles — left.
Repeat the process for the left hand. You’ll get another silver rupee and see the final symbol — right.
Small Key 1
Head to the east side of the room. Pull the switch to open the gate, and head through the door.
Drop down and climb out of the water to the left. Carefully cut down and dispatch the Skulltulas. In the next hall, there’s a plaque on the left, telling you to hit the gems on the lock in the Secret Order.
Hit the top, bottom, left, and right gems with slashes from those directions.
In the next room, cut down the two Skulltulas with your Beetle, and then swim over and climb out of the water in the southeast corner.
Face north, and jump off the ledge onto the lily pad below you — this will flip it over and reveal a tunnel.
Dive under and swim through that tunnel on the east wall. Spin through any barricades you come to. At the other end, climb out and go through the door.
Open the chest on the other side for the Small Key.
Drop off the ledge, and head to the southeast corner of the room. Ride the water spout up to the ledge. Cross along this ledge and back into the main room.
Stalmaster mini boss fight
Take the Small Key to the locked door in the center of the room and step through. Drop down through the hole.
The fight against the Stalmaster is a lot like fights against regular Stalfoses. You have to attack from the direction it’s not blocking. Stalmaster just has extra arms and swords.
Shield Bashing to parry attacks will knock Stalmaster’s arms off, allowing you to land a couple — but no more than two — free hits.
Once Stalmaster is defeated, smash all the skulls in the room for some hearts, and then head through the door.
Open the chest in the next room for the Whip.
Back in the center room, equip the Whip, and target the valve. Whip it to attach the Whip to it, and then flick the Whip to spin it. This will open another water spout to ride up to the floor above.
Repeat this process on the next floor, and go through the door to return to the main room.
Swim and hop over to the platform on the outer edge of the room near the bird statue. Follow it around counterclockwise.
Use your new Whip to swing across the gaps until you reach a chest with the Dunegeon Map.
Reach level B1
Navigate the lily pads over the western side of the room. Look for the upside-down one with the roots sticking up.
Get close, and flip it over with your Whip. Hop onto it, and use your Whip to pull the switch on the wall and shut off the waterfall there.
Dive into the water and head through the tunnel heading west. When you exit, loop around the giant fish head statue to find a chest with a red rupee.
Head to the gate on the west wall. Stand close, and you’ll be able to Whip the switch through the bars. Pull the switch to open the gate and continue through.
Follow the right wall up the ledges there. Whip across to the vines and climb up.
Hop onto the rotating cylinder, and climb up. Ride it around to a platform hidden behind it on the west wall. Catch your breath there, and then continue around to the south.
Face east. Use the Whip to swing from the branch sticking out of the wall. Turn yourself a little to the left so that you’ll jump to the switch instead of the vines. When you land on the switch, you’ll open the gate above you.
Backtrack, and swing from the same branch. Land on the vines this time, and climb into the room you just opened.
Use your Whip on the valve to lower the water in the main room. Step onto the ledge to the northwest. Drop off to the left to find a Goddess Wall.
Hop into the whirlpool, and let it carry you down.
Small Key 2
When the pipe spits you out, turn around and climb out of the water to find an Amber Relic and a bird statue.
Use your Beetle to cut down the Skulltulas. When the easternmost one falls, it’ll flip over the lily pad under it and reveal a tunnel. Swim through, and climb out on the right.
Get close to the bars, and Whip the Bokoblin on the other side to steal the Small Key from him. Use it on the locked door to the north.
Follow the tunnel east, and swim through the pipe at the end.
Lower the Great Statue
Swim to the bird statue south of you. Over on the east side of the room, Spin Jump to land on the ledge.
Use your Whip to flip over the lily pad in the southeast corner. Climb the vines above it.
Follow that path north, and drop off the ledge onto the lily pad in the middle of the room. You’ll open a new underwater tunnel.
Dodge the Froaks and follow the tunnel to the end. When you return to the main part of the room, turn right to find a valve. Whip it open.
Retrace your steps to get back to the lily pad you just raised. Use your Whip to flip it over, and then cross to the west side of the room.
Follow the path and Whip the switch to open the gate at the end.
Deal with the Furnix, and then climb onto the vines to your right.
Climb straight down to find a ledge under the one you were just on. Open the chest there for a red rupee.
Climb back onto the vines, and work your way counterclockwise (south) along the wall.
At the end, Whip open the valve to open a shortcut. Use your Whip to latch onto the branch on the wall. Yank it down. This lowers the Great Statue in the center of the room.
Restore the Great Statue
Head back into the Great Statue through the same door you used earlier. Drop to the bottom, and head through the next door as well.
Turn left and follow the path around to the east, clearing the Cursed Bokoblins as you go.
At the end, you’ll find a Goddess Wall and a plaque telling you to strike the gemstone in the eye.
Head back to the south, and jump across the lily pads heading west.
When you reach solid ground, face back to where you came from. Fly your Beetle into the eye socket of the huge face carving and hit the gemstone inside.
Use your Hook Beetle fly through the tunnel you just unblocked — starting to the south and flying north — and pick up the Bomb Flower as you pass. Fly it to the boulder on a pillar north of you (take a right as it exits the tunnel).
Walk north along the path, and then turn left. Whip-swing across to the platform you just cleared.
Jump onto the vine-covered, rotating pillar and climb to the top. Hop to the next pillar, and ride it around to the platform to its southeast — not the first one you pass, but the second.
Follow that path west and climb the vines. At the top, Whip the lever to the left — this switches the direction everything is spinning.
Drop down onto the spinning disk and ride it to the north. Follow the path up. Ride the pillar around the platform to its southeast. Follow the path and vines up, and throw the same lever.
Return to the pillar and ride it around to the platform to its south.
Drop into the big round room. Climb the rope hanging in the middle.
At the top, read the plaque. There’s a bird statue and an Amber Relic to your right. Pull the switch on the wall to your left.
Step onto the platform that extends, and Whip the lever up.
Slide back down the rope you just climbed.
Exit the room to the east and Whip the valve on your right.
Drop down to the level below, and head north to the chest in the center of the map. Open it for the Blessed Idol.
Many Cursed Bokoblins will claw their way out of the ground as the Great Statue lowers from above you. Ignore the zombies and sprint south. Climb out of the bowl-like depression, and watch as the Statue squishes down.
Head into the Statue, and ride the water spouts up to the very top.
Place the Blessed Idol into the lock — the statue part goes in first.
Turn around and take the stairs to the top. Whip open all four valves there.
Ancient Automaton Koloktos boss fight
When the elevator stops, collect the hearts and save at the bird statue. Head up the stairs to begin the Ancient Automaton Koloktos boss fight.
For the first phase of the fight, Koloktos will toss its two blades. They’ll spin around the room, but you can duck behind a pillar for cover.
Try to stay close to Koloktos and watch for an overhead strike. While its arms are stuck, Whip the arm joints to detach the arm. Repeat this a few times until its red weak point in its chest is exposed. Get in close and attack as much as you can.
It’ll reattach its arms. Repeat the process.
After a couple rounds of that, Koloktos will lift itself out of the ground.
Avoid its horizontal attacks by running away. It might also summon a few Cursed Bokoblins — do your best to ignore them.
Your only goal here is to draw another overhead strike. When its arms are stuck, detach one. This time, pick up the giant sword it drops.
Approach Koloktos, and do a horizontal swing to detach its legs. Swing vertically to remove its arms. Once it’s safe, lock on and attack its body and chest as many times as you can. You’ll break the cage in its chest and deal some damage to the weak point.
Keep repeating the process until you win.
When Koloktos is defeated, grab the Heart Container as you head for the door. On the other side, Skyward Strike the altar.
Fi will use the flames of Farore to upgrade your sword to the Goddess Longsword that does double damage.
She’ll also tell you to head back to the Isle of Songs inside the Thunderhead.
