Autobuild Schematics Guide — All 32 Depths Locations

Autobuild is one of the most powerful abilities in Tears of the Kingdom. After unlocking the base ability on the Great Sky Island, you can expand it by finding Autobuild schematics hidden in treasure chests throughout the Depths. Each schematic teaches Link a pre-designed Zonai construct — from simple sleds to complex combat walkers.

Quick Stats

| Stat | Detail | |------|--------| | Total Schematics | 32 | | All Located In | The Depths | | Access Method | Treasure chests (gold/large chests) | | Prerequisite | Autobuild ability unlocked | | Ability Source | Great Sky Island — Construct Factory | | Zonai Cost | Each build costs Zonai Charges based on complexity |

How Autobuild Works

Before hunting schematics, understand the system:

Unlock Autobuild on the Great Sky Island by completing the Construct Factory puzzle
Open schematic chests in the Depths — they auto-add to your schematic library
Access your schematics via the Autobuild menu (hold L → Autobuild)
Select a schematic and place it — Autobuild assembles the construct using nearby Zonai parts
If parts aren't nearby, it costs Zonai Charges to summon them automatically
Favorite schematics to pin them at the top of your list

Schematic Categories

Schematics fall into several categories:

| Category | Examples | |----------|---------| | Transport | Sleds, Carts, Boats, Hovercrafts | | Combat | Rocket Sleds, Cannon Platforms, Walking Mechs | | Utility | Fans + Platforms, Elevators, Bridges | | Advanced | Hoverbikes, Wing Gliders, Tank variants |

Prerequisite: Unlocking Autobuild

You must unlock Autobuild before schematics are functional.

Location: Great Sky Island — Construct Factory How to reach it:

On the Great Sky Island, find the Construct Factory (northwestern section)
Navigate through Zonai ruins to reach the factory core
Solve the multi-room puzzle involving moving platforms and Zonai mechanisms
Receive Autobuild from the Steward Construct at the end

> Note: You can collect schematic chests before unlocking Autobuild, but they won't register until the ability is active. Don't worry if you find chests early — they retroactively unlock.

Navigating the Depths for Schematics

The Depths are dark, Gloom-covered, and disorienting. Follow these tips:

Preparation Checklist

Brightbloom Seeds — Carry 20+ for lighting
Gloom-resist food — Cook Sundelion meals before descending
Stamina food — Long distances between Lightroots
Arrows — Shoot Brightbloom Seeds ahead to light paths
Fast horse or vehicle — Distances are vast; build a quick cart

Navigation Method

Activate Lightroots first — They light up the ceiling of the Depths (visible from above on the overworld map)
Use Brightbloom arrows — Attach Brightbloom Seeds to arrows and shoot them ahead for long-range lighting
Build a sled — Even without a schematic, a simple fan + wooden platform carries you fast
Follow ore deposits — Ore veins often appear near key locations
Look for large gold chests — Schematic chests are the large golden chests, not the standard wooden ones

Most Useful Schematics

Not all schematics are equally valuable. Here are the must-have ones:

Top Tier

Compact Hoverbike (#26) — The single most useful build in the game; fast aerial transport
Twin Fan Speedboat (#7) — Essential for water zones
Rapid Fan Glider (#11) — Best schematic for Depths traversal
Armored Tank (#19) — Best for Depths combat encounters

Solid Utility

Rocket Cart (#2) — Fast ground transport
Hover Platform (#4) — Large carrying capacity, stable
Flying Wing (#23) — Long-range gliding
Sand Skimmer (#17) — Essential for Gerudo/desert Depths

Situational

Fire Cannon Sled (#5) — Great against ice enemies
Spiked Bulldozer (#8) — Mining and combat hybrid

Zonai Charge Management

Building from schematics costs Zonai Charges when parts aren't present in the environment.

Charge cost tiers:

Simple sleds (3-4 parts): 1-2 Large Zonai Charges
Mid builds (5-8 parts): 3-5 Large Zonai Charges
Complex vehicles (9-12 parts): 6-10 Large Zonai Charges
Hoverbike: ~3 Large Zonai Charges (efficient!)

Stocking up:

Farm Zonai Charges at Construct Factories (Great Sky Island and sky islands)
Sell ore and buy Large Zonai Charges from vendors
Disassemble unused Zonai devices in your environment for charge recovery
The Crystal Refinery on Sky Islands converts Crystallized Charges to usable ones

> Tip: Always try to build near existing Zonai device caches. Many Depths mines have Zonai parts in crates — build near these to save charges.
