A Mystery in the Depths Walkthrough



Follow Josha

Wait for Josha at the mural next to the double doors and talk to her. She will give you 10 Giant Brightbloom Seeds and 10 Arrows after the briefing.

Follow the Statues in the Depths

Open your map and switch to the Depths layer. Fast travel to Iayusus Lightroot as this is the closest Lightroot to the first of the statues.

Turn southwest to find the first statue next to Robbie's campfire and start following the direction each of the statues are facing.

Don't forget to light up your path with Brightbloom Seed-fused arrows!

Activate Nihcayam Lightroot

Make sure to activate Nihcayam Lightroot when you pass by it after the first few statues. A little further south and you will run into a Frox, which is like a frog talus.

Reach The Great Abandoned Central Mine

Continue following the statues' direction and you will end up in the Great Abandoned Central Mine.

Press on and examine the mark next to the suspicious researchers to gain the Autobuild ability! You can be like some sort of technomancer now.

Use Autobuild

The researchers will now ask you to demonstrate the ancient power on the dismantled vehicles behind.

First, reattach the wheel on the first vehicle so that its fixed state registers in your Autobuild history. Next, move to the vehicle on the other pedestal and use Autobuild to recreate the first vehicle.

Fight Master Kohga

Oh, it's the banana guys! What a surprise. After revealing themselves, Master Kohga will trap you into an arena where you have to defeat him and his own contraption (Nope. You can't use Ultrahand to disassemble his vehicle).

Report back to Josha

Whaddayaknow, he's actually good at crafting stuff. Anyway, open the chest for a Huge Crystallized Charge and before you leave, talk to the Steward Construct south of the travel point for the Fanplane Schema Stone.

When you're ready, fast travel to Lookout Landing and find Josha to receive the Hot-Air Balloon Schema Stone.

Demonstrate Autobuild to Josha

Head outside and repair the broken balloon using the schema Josha gave you. Activate Autobuild, select the Hot-Air Balloon schematic, and select the parts on the ground to repair it.

Do so and you will be rewarded with a Large Zonaite as well as the quest's completion.

Now to continue investigating the strange phenomena. Next stop: the Gerudo Desert!

How to Beat a Frox

Throw a Bomb Flower at Its Mouth

Zelda Tears of the Kingdom TotK - bomb flower exploding inside a Frox

Try not to get too close to a Frox as you might get inhaled or body slammed. Keep your distance while waiting for it to inhale or charge at you with its mouth wide open before throwing a Bomb Flower at its mouth. You can also use Bomb Flower-fused arrows for this.

It will chow down on your explosive treat until it blows inside its mouth and get the Frox stunned.

Attack Its Deposits With Hammers

Zelda Tears of the Kingdom TotK - attacking a Frox ore deposit

A Frox will be incapacitated for a while after successfully doing the step above. During this time, climb on its back and attack the ore deposits with a hammer. Hammer-type weapons (or any weapon fused with a rock) deal way more damage than bladed ones like sword and spears.

Another tip is to perform a charged attack with a hammer between two ore deposits to maximize damage.

Using the Autobuild Ability

Zelda Tears of the Kingdom TotK - using the Autobuild ability

The Autobuild ability allows you to instantly recreate vehicles, machines, and other makeshift objects you crafted with the Ultrahand ability.

Anything you craft with Ultrahand will now be stored in the Autobuild history. Activate Autobuild and select a project from the list to recreate it, as long as you have the necessary materials lying around (devices pulled out from Zonai Capsules work too) and enough Zonaite.

How to Beat Master Kohga

Snipe Him Off His Ride

Zelda Tears of the Kingdom TotK - knocked off Master Kohga

Since you can't dismantle his vehicle or damage it, the only way to defeat Master Kohga is to attack him directly. Nock an arrow and shoot Master Kohga as you avoid getting run over to stun him for a while. Scoring a headshot will even knock him off his ride completely!

Attack him with all you got before he recovers and teleports back to his vehicle. Rinse and repeat until his health bar is depleted.
