Tears of the Kingdom Schematics: All 12 Schema Stones and 34 Yiga Schematics

Schema Stones and Yiga Schematics are the designs for Autobuild: pick up one and Autobuild can put that contraption together for you. This page lists all 46 with coordinates, what each unlocks, and how to get it.

Where are the 12 Schema Stones?

The name is the design the stone unlocks. Three come from Master Kohga — in Game8’s words, “Given by a Steward Construct after beating Master Kohga”, once in each of three abandoned mines — one from Josha after A Mystery in the Depths, and the other eight are found out in the world; for those, the table gives Game8’s nearest travel point.

Where are the 34 Yiga Schematics?

All 34 are in the Depths, each in a chest that opens once the enemies around it are beaten. Coordinates are X, Y as the in-game map shows them; the landmark is the nearest named place in the Depths; for 18 of the 34 it is a mine. By region: Gerudo and Hyrule Field 7 each, Akkala 4, Hebra, Lanayru, Necluda and Tabantha 3 each, Eldin 2, Faron and Great Hyrule Forest 1 each.

Where does this data come from?

• Yiga Schematics: the game’s placement data as served by zeldamods’ radar for objmap-totk — the 34 chests whose contents are a Yiga Schematic. All 34 agree with Game8’s list; Game8 prints the Aerial Cannon’s X as -130, where the chest is at 131.
• Schema Stones: positions and how to get each are Game8’s (the game gives them through events, so the placement data has no position for them).
• Names: the game’s own text (TotkText, game version 1.2.1).
