Blueprints are one of the game’s collectibles and allow you to unlock more weapons and equipment in Piero’s shop. They are hidden throughout the missions just like any other collectible, but you cannot use The Heart item to locate them. Some Blueprints have multple locations, so it’s possible to miss them the first time and still unlock them in another mission.

Lens Magnification

This is one of the first Blueprints you can get in the game, as you will be able to buy it from Griff the Scavenger during the High Overseer Campbell mission or during the House of Pleasure mission. He is located right by the Whiskey Distillery and you’ll have to rescue him from some Bottle Street Gang members before he’ll sell you goods. It costs 200 coins. This Blueprint unlocks Mask Optics 2 for purchase in Piero’s Workshop.

Sokolovs Formula

This is one of the first Blueprints you can get in the game, as you will be able to buy it from Griff the Scavenger during the High Overseer Campbell mission or during the House of Pleasure mission. He is located right by the Whiskey Distillery and you’ll have to rescue him from some Bottle Street Gang members before he’ll sell you goods. It costs 200 coins.

You can also find it on a desk in Sokolov’s room during The Royal Physician mission. It will unlock Sokolov’s Health Elixir for purchase from Piero’s Workshop.

Bonded Galvani Weave

In High Overseer Campbell , you can find this inside of a locked cabinet in the workshop in the Back Yard area. In order to open the cabinet, you need to find the key, which is inside of a glass jar on the table.

It can also be found in Daud’s office during The Flooded District in a locked chest, which requires Daud’s Key. This unlocks the Improved Armor upgrade for purchase at Piero’s Workshop.

Incandescent Paste

This blueprint is located in the Dunwall Whiskey Distillery during the House of Pleasure mission. Once you’re inside the main building, there is a room on the right with a valve, which opens the door right next to it. Instead of turning the valve, look above the entrance to find an opening you can get through with Blink or a double jump.

It can also be found in The Flooded District mission, in the Gateward Tunnel section. It can be found in the cellar, which is near the exit of this area. This blueprint unlocks the Incendiary Bolts for purchase at Piero’s Workshop.

It’s easiest to jump through the opening above the doorway to get the Incandescent Paste blueprint.

Folded Galvani Resin

This blueprint can be found in The Royal Physician mission. It can be found in the first warehouse that you must pass through. Keep going up the stairs until you get to the cart, where you’ll find the blueprint on the desk nearby. These can also be found in The Flooded District , in Daud’s locked chest (requiring Daud’s Key). These blueprints unlock the Boot Stealth upgrades for purchase at Piero’s Workshop.

Spiked Grenade Housing

This blueprint can be found in the Lady Boyle’s Last Party mission. When you first enter the Boyle Estate grounds, you will need to hand over an invitation to the guard. When you are allowed inside, head inside of that guard station to find the blueprint.

It can also be found in The Flooded District mission, in the Gateward Tunnel section. When you arrive here, go forward into the wreckage and to the right (there’s a guy here trying to lift someone). Enter the building and immediately go to the right, where you’ll find the blueprint. This unlocks the Sticky Grenade for purchase at Piero’s Workshop.

Small Scale Combustion Refinement

This blueprint can be found in the Return to the Tower mission. Inside of the tower, go to the second floor and find General Tobias’ office, where you’ll find the blueprint. It can also be found in The Flooded District , in the Central Rudshore area. It is inside of a wrecked train car in the rail station. This unlocks the Explosive Bullet upgrade for purchase at Piero’s Workshop.
