Tears of the Kingdom Master Kohga: All Four Mine Fights

The two researchers standing over an inactive Steward Construct in the Great Abandoned Central Mine are not researchers. They watch Link wake the construct with his right arm, watch it hand him Autobuild, ask him to demonstrate it on their broken carts, and then call out "Oh, Maaaster!" before teleporting away. They are Yiga Footsoldiers, and the man who appears behind Link is Master Kohga.

He survived the fall down the Yiga Clan Hideout Chasm that ended his Breath of the Wild fight, and he wants the power you just took. Our Depths guide sends you to that mine for Autobuild and stops there. This guide covers the rest: the four Abandoned Mines where you fight him, the route to each, how to knock him off each vehicle, and what the whole chase pays. Quest text, rewards and chest coordinates come from Zelda Wiki. Routes and Lightroot coordinates come from Thonky's walkthrough, and each one is credited where it is used.

The researchers were Yiga all along

The first fight belongs to a Main Quest, not a side one. Josha gives you "A Mystery in the Depths" at Lookout Landing. Zelda Wiki lists one cleared "Regional Phenomena" quest as the prerequisite, and Thonky adds that "Camera Work in the Depths" has to be done first. Josha has pieced a mural together from Depths slate fragments. It shows a chain of statues, each looking at the next, ending at a temple-like building. She hands you 10 Giant Brightbloom Seeds and 10 arrows, because she is not allowed down there herself.

Thonky puts the first statue southwest of Iayusus Lightroot. Follow where each statue is looking and you reach the Great Abandoned Central Mine, which sits beneath the Great Plateau. Thonky also notes you can walk there and take Autobuild without starting Josha's quest at all.

Zelda Wiki's page on the Yiga plot, "Operation Steal the Ancient Power", explains the ambush. Yiga Clan notebooks describe Kohga sending a reconnaissance team to this exact mine to find a power that builds vehicles in an instant. You found it for them.

Beat him and the Main Quest is not quite over. Report back to Josha and she gives you the Hot-Air Balloon Schema Stone, then a Large Zonaite once you use it to rebuild Robbie's broken balloon. The chase itself continues as the Side Adventure "Master Kohga of the Yiga Clan."

Four mines, four vehicles

Each mine sits under a surface landmark, per Zelda Wiki's location pages, and Kohga brings a different build to each one.

The Schema Stone column comes from Zelda Wiki's schematic table, which places one stone at each of these four mines. We could not confirm per-fight Tears of the Kingdom health figures against a primary source, so there are none here.

Fight one: the spiked buggy under the Great Plateau

Kohga teleports into the courtyard and summons a buggy with a spiked ram, then drops boulders on you while he drives. Per Zelda Wiki:

• Shoot him. An arrow hit throws him out of the buggy and half-buries him in the ground, and you get free hits until he climbs out.
• Recall the boulders. They go straight back at him.
• Get behind him later. He adds wooden panels that block shots from the front and sides. The back stays open.
• Make him hit a wall. At low health he bolts on two Rockets and charges. Sidestep and he crashes, which stuns him.

Thonky adds two practical notes. Ultrahand cannot grab his vehicle, but you can sidestep a pass and jump onto it to hit him directly. And there is no point stealing it, because he makes it disappear soon after.

A stone chest with a Huge Crystallized Charge appears when he flies off on a Wing with four Fans. A Steward Construct then tells you he was heading for the "former Gerudo Mine" and points you at the light in the distance, Koradat Lightroot, below Tadarok Shrine, where the statue trail starts. The other construct in the mine hands you the Fanplane Schema Stone plus the parts to build one. Thonky's trick is to set the Fanplane on the rail that points toward the Lightroot and hit a fan.

Fight two: the Fanplane under Gerudo Town

The statue trail southwest

The Statues That Point the Way are carved to look like the people of their region, per Zelda Wiki, and a Yiga notebook says following their line of sight leads to the nearest abandoned mine. Thonky's route from Koradat:

To skip that Frox, Thonky's line is to Ascend the slope just west of Amakawis Lightroot and glide down north of the Frox, past the gloom.

At the mine Kohga is trying to wake a Steward Construct with his own right hand, and it is not working. He blames you, and summons a Fanplane. Zelda Wiki says it starts with Flame Emitters underneath and swaps them for a Cannon later. The fix is altitude. Zelda Wiki says the arena holds Zonai devices for exactly that, and lists Fans, Hover Stones, Rockets and Springs in this mine. Thonky's version is to hit a Spring, ride it up, and draw your bow to slow time in midair. Keese Eyeballs fused to arrows home in on a target, which our Fuse guide covers, and they suit a target that will not hold still.

After the first hit he starts lobbing explosives. Later he raises a screen across the front of the plane, and Thonky says boards go up on the sides too, so you need to be above him to land a shot.

Afterwards he announces that "Operation Steal the Ancient Power" is over. The new plan is to collect crystallized charges to rebuild a weapon for the Demon King, and he leaves for the "Eastern Abandoned Mine." A chest with a Huge Crystallized Charge appears below the conical device at -3841, -2914, -0486. The second Steward Construct gives you the Hovercraft Schema Stone, a stone chest in the isolated building at the mine's far south holds a Large Crystallized Charge, and Thonky puts Gonatoyros Lightroot above the mine, reached by Ascending.

Fight three: the Headlight Raft under Zora's Domain

The chasm that skips the walk

The Steward Construct at Gerudo sends you to the surface. It suggests the Lanayru Wetlands Chasm or the East Hill Chasm in the mountains near Kakariko Village, both of which have statue trails to the Abandoned Lanayru Mine. Thonky places the first north of Jonsau Shrine and the second northeast of Kakariko.

There is a quicker way. Zelda Wiki says the Chasm Under Zora's Domain drops straight into the mine. It opens inside the Cave Under Zora's Domain, the same cave that holds the Vah Ruta Divine Helm in our sages guide. Thonky's directions are to go southwest from Mogawak Shrine, down the waterfall, and through it. Kawagom Lightroot sits just south of the mine at 3298, 0419, -0749.

This time he brings backup. He teleports onto the water, summons a Headlight Raft and two Yiga Footsoldiers with Duplex Bows, and tells them to attack. Zelda Wiki notes vehicles nearby that let you close the distance. Thonky's specifics:

• Take the small raft at the end of the dock, and let go of the controls before you try to swing.
• Use his raft. When you stun him and he vanishes, his raft stays behind. It is slower than yours, but it does not roll side to side.
• Wait for the bomb. Later rafts put a force field around him, but he drops it to throw. That is your shot.

Zelda Wiki adds that at low health he throws boulders and puts up his energy screen. If you would rather shoot from above, a Rocket fused to a shield launches Link straight up, per the Fuse guide.

He blames a wet steering stick, says the Yiga have found the Demon King, and leaves for the "Northwestern Abandoned Mine." The chest at 3296, 0574, -0749 holds the third Huge Crystallized Charge. The Steward Construct gives you the Bolt Boat Schema Stone, and a Large Crystallized Charge sits in a chest on a ledge along the wall west of the mine. Three Water Octoroks patrol the water.

Fight four: the Ultimate Weapon under Rito Village

One chasm in

Zelda Wiki says the Abandoned Hebra Mine is cut off from the rest of the Tabantha Frontier Depths, and the Rito Village Chasm is the only way in. The Lanayru construct warns that the old route from Hyrule Ridge no longer works, and Thonky warns that a statue trail you may find heading that way dead-ends.

The Rito Village Chasm is in a small cave on the east side of the village. During the quest Ponnick stands on the village's southern edge and points it out directly below him. Thonky's route: go southeast from Gatakis Shrine, look down from the cliff edge to find Ponnick, and glide into the chasm he shows you. Sikatag Lightroot is west of where you land.

Kohga is waiting in front of a Relay Base. The Yiga have their crystallized charges, and he unveils the Ultimate Weapon: a Crafter Construct, the same type of construct as Mineru's body and the Seized Construct, rebuilt by the clan. An electric fence rises around the arena. On the Switch 2 Edition, a Zelda Notes Voice Memory names the machine the Mecha Kohga 5000 - Deluxe.

Zelda Wiki says it fights much like the Seized Construct and shares that fight's weakness: knock it into the electric fence and Kohga falls out, stunned, until he climbs back in. Hitting the construct itself works too and will eventually finish him. Thonky's breakdown of what it does:

• Shoot Kohga whenever you can see him. It knocks him out of the cockpit.
• Use a heavy weapon to knock it into the edge of the arena, but not while it is winding up a punch. Dodge the punch first, then go back in.
• Run behind it when the arms point at you. From a corner it fires electric beams from both arms that sweep inward, and they cannot reach its back.
• Shoot the bombs early. It also sends three big bombs at you one by one. Arrows set them off at range, and Recall sends the last one back into Kohga.
• Expect a force field later, plus a punch or a shield if you crowd it.

When the construct falls apart, Kohga summons the Kohga Rocket: 11 Rockets, an Iron Pole and a Spiked Iron Ball, per Zelda Wiki. It tilts the wrong way and fires him out of the Rito Village Chasm. Two chests at about -3497, 1850, -0415 hold the fourth Huge Crystallized Charge and a Diamond. The Steward Construct gives you the Rocket Platform, a Hover Stone, Battery and Rocket build that costs 15 Zonaite to Autobuild from nothing. A Large Crystallized Charge sits in a chest on top of the forge.

What the chase pays

The value column uses the game's own item text, which Zelda Wiki quotes: a Huge Crystallized Charge equals 100 normal crystallized charges and a Large one equals 20.

A Crystal Refinery's Steward Construct asks for 100 crystallized charges per Energy Well, so the 460 charges in that table are four Energy Wells with 60 toward a fifth. At a Forge Construct a crystallized charge costs 3 Zonaite, so 460 charges is 1,380 Zonaite you do not have to mine, by my arithmetic. Our Ultrahand and Zonai devices guide covers what a bigger Energy Cell buys you. The Diamond sells for 500 rupees, the highest material price in our rupee guide.

The Schema Stones are the other half. Zelda Wiki says a mine's Steward Construct also hands over the parts to build its design, and that at most mines the build helps you reach a treasure chest. Thonky's examples on this route: the Hovercraft toward lights southwest of the Gerudo mine, the Bolt Boat past the Octoroks, and the Rocket Platform up a chain of floating platforms to a chest holding a Large Crystallized Charge.

Once he is gone, he stays gone

There is no rematch. Zelda Wiki lists Master Kohga among the few Tears of the Kingdom bosses that cannot be fought again, alongside the Seized Construct. The twelve Boss Rematch arenas in the Depths only hold Colgera, Mucktorok, Marbled Gohma and Queen Gibdo, and each win there pays a Huge Crystallized Charge too. Our boss guide covers those four.

Thonky warns of a side effect. From the moment you beat Kohga at the Hebra mine, it says, Yiga start appearing in the overworld and attacking you. It suggests skipping the last fight if you would rather not deal with that, at the cost of the Huge Crystallized Charge, the Diamond and the Rocket Platform stone. Zelda Wiki's quest page does not mention this, so treat it as Thonky's report. Breath of the Wild did something similar after its Kohga fight, which our Yiga Clan Hideout guide covers. The counter is unchanged: Zelda Wiki says the full Yiga Clan Attire makes Footsoldiers and Blademasters treat Link as one of their own.

Kohga also has more to say than the quest gives him. On the Switch 2 Edition, Zelda Notes adds his Depths Voice Memories, the first of them below the Yiga Clan Hideout Chasm. Our Switch 2 Edition guide has the rest.

Quick Action Checklist

• Start with "A Mystery in the Depths" from Josha at Lookout Landing. The first statue is southwest of Iayusus Lightroot (Thonky), and the mine is under the Great Plateau.
• Fight one, spiked buggy: shoot him out of the seat, Recall the boulders, get behind the panels, and sidestep the rocket charge into a wall.
• Talk to the Steward Constructs after each fight. Through fight three one points you to the next mine, and at every mine one hands over a Schema Stone and the parts.
• Fight two, Fanplane, under Gerudo Town: follow the statues from Koradat Lightroot, then use a Spring and slow-motion bow shots to get above him.
• Fight three, Headlight Raft, under Zora's Domain: drop in through the Chasm Under Zora's Domain, take the dock raft, and fire when he lowers his shield to throw.
• Fight four, Ultimate Weapon, under Rito Village: the Rito Village Chasm is the only way in, per Zelda Wiki. Knock the construct into the electric fence, get behind it when the arm beams start, and Recall the last bomb.
• The chase pays 460 crystallized charges' worth (four Huge, three Large), which is four Energy Wells, plus a Diamond and four Schema Stones.
• There is no rematch. Per Thonky, Yiga start ambushing you on the surface after the final fight. Full Yiga Clan Attire keeps them friendly.
