There are so many collectibles to find in Bethesda and Arkane Studios' Dishonored series. These range from mysterious runes and bone charms to even paintings (Although how Corvo and Emily manage to drag all this loot around during their mission is anyone's guess). One of the most essential types of collectible to find is the blueprints.
While the first Dishonored game only had seven blueprints to find, Dishonored 2 has 19 scattered around the various beautiful levels. It can be quite a challenge trying to track them all down, but necessary. Each blueprint will unlock a special upgrade which will help with the adventure.
19 Dispersed Incendiary Release
This blueprint is a must-find if players want access to incendiary bolts to set their enemies aflame.
During the Edge Of The World mission, players can climb up to the second floor of the building opposite the beached whale at the docks. This is Alistair Fletcher's office. The blueprint will be in the safe, which is luckily unlocked.
18 Fire Hardening Treatment
To have extra damage dealt from crossbow bolts, players must find this blueprint.
Head to the Edge Of The World mission and reach the third floor of the Overseer Outpost. Players can grab the Fire Hardening Treatment blueprint off the desk. Just make sure to deal with the many overseers patrolling this area first.
17 Combat Sleep Dart Formula
This blueprint from the Good Doctor mission ensures instant unconsciousness with the player's sleep darts.
It can be found in a room above the lobby, to the right of the main doors. Players can climb up to a walkway and head around the corner to a rat-infested room. The blueprint is inside a locked safe, but luckily the code is written down on the table a few steps away.
16 Mercury Vapor Distillation
This blueprint allows access to stinging bolts, which help cause itchy distractions.
During the Good Doctor mission, players can head up to the top of the main stairs, keeping an eye out for traps, and unlock Joe Hamilton's quarters. The keen-eyed Emily (Or Corvo) can find the key near Joe in the institute's disease treatment wing. Once inside Hamilton's quarters, the blueprint will be right on his desk.
15 Pyro-Sonic Casing
Howling blots can be unlocked with this blueprint. These bolts temporarily blind those in the blast radius, allowing for a quick getaway.
This blueprint can be found on the Clockwork Mansion level. First, players need to buy the key from the black market shop in the Lower Aventa area for 250 coins (Or with the five-finger discount). Next, they need to head to the security booth in the carriage station. Unlock the door and stroll right in to grab it off the desk.
14 Alloy Polarization
If players struggle against the menacing clockwork soldiers, this blueprint is handy as it makes bullets briefly stun these robotic baddies.
During the Clockwork Mansion mission, players need to reach the grand guard office's third floor in the Upper Aventa district. There will be a briefing room on this floor, with three tables. The blueprint will be on the middle table.
13 Conductive Filaments
This blueprint has shocking results when unlocked. It allows stun mines to chain their shocks onto another person.
This blueprint can be found in the Clockwork mansion. Head to the waiting room, but don't step inside it. Instead, pull the configuration lever nearby to replace this room with an office. The blueprint will be on the desk in this new room.
12 Slug Splintering Wedges
Instead of relying on supernatural powers, players can have their bullets bounce off hard surfaces to perform astonishing tricks with this innovative blueprint.
While navigating the Clockwork Mansion, players can find this blueprint on Kirin Jindosh's laboratory's top level. It will be hidden in the drawer of his desk, next to the painting of Anton Sokolov.
11 Reverberation Tubing
Once this blueprint is discovered, players can upgrade the howling bolts to scare away witches and wolfhounds.
To find this blueprint, players should go on the Royal Conservatory mission. Before heading into the conservatory itself, head to the right on the street in front of it. There will be a house at the end, with a boarded-up stairway. The blueprint will be up for grabs on a desk on the top floor.
10 Triggered Housing
With this dangerous upgrade, grenades will explode instantly upon contact with living creatures.
Inside the Royal Conservatory, on the first floor, there will be a small workshop to the side of the main hall area. Make sure to avoid the teleporting witches before heading into the workshop and grabbing the blueprint off the desk.
9 Configurable Grooving
With this blueprint, masterwork crossbow upgrades will be available to purchase, unique to Emily and Corvo.
This blueprint is given as a reward for completing a side quest during the Royal Conservatory mission. The quest and reward are provided by the shopkeeper at the black market store. They want the protagonist to retrieve the Roseburrow prototype from the security room within the conservatory.
8 Secondary Coiling
With the help of this blueprint, the spring razor mines can now be set off twice in a row. These mines will be quite an unwelcome surprise for enemies, in contrast to the more enjoyable surprises players stumble upon in the series.
During the Durst District mission, players can head down to the Crone's Hand Saloon's basement. The blueprint will be on a crate near a tied-up Overseer.
7 Spiked Grenade Housing
This blueprint unlocks sticky grenades, which are especially useful when dealing with the clockwork soldiers.
Once again, in the Crone's Hand Saloon on the Durst District mission, this blueprint can be discovered in a big blue metal box, resting beside a strange mask. The box is located on the second floor of the saloon.
6 Firing Chamber Pivot
Both Corvo and Emily get a little more variety with this blueprint. They now have unique pistol upgrades designed explicitly for them.
During the time-bending chaos of the A Crack In The Slab mission, players can head to the manor's vault. Its doors will be open in the present for easy access, then jumping into the past will allow for the safe inside to be opened to reveal the blueprint.
5 Small-Scale Combustion Refinement
Players will be able to purchase explosive bullets after finding this blueprint.
The blueprint can be found in Carlos Marletto's apartment during the Grand Palace mission, near the wall of light on Ravina Boulevard. His apartment is locked, but luckily players can swipe his key from the register at the nearby safe shop.
4 Folded Galvani Resin
The elusive Corvo (and Emily) can be extra sneaky with this blueprint, as it will lessen the sound their boots make while they run around.
While exploring the Grand Palace, players can sneak down to the cellar. There will be a hidden button on one of the shelves. It will reveal a top-secret entrance to the Duke's top-secret chamber where the blueprint will be...not so secretly hidden, right on the table.
3 Blade Conversion
As with the other weapons of choice, the sword can have master upgrades once this blueprint is discovered.
During the Grand Palace mission, players can visit Duke Luca Abele's impersonator in his office. After a friendly chat, stick around to snoop through the cabinet opposite his desk. The blueprint will be waiting inside. Be careful of the clockwork soldier guarding this room too.
2 Dual-Layered Galvani Weave
With this blueprint, players can upgrade their armor to a master level to reduce damage and visibility.
This one is relatively easy to find. At the very start of the Death To The Empress mission, Corvo or Emily can retrieve this blueprint from the table in the Dreadful Wale's briefing chamber.
1 Counter-Blast Inversion
Finally, the masterwork upgrades for grenades becomes available with this blueprint.
This final blueprint is found on the last mission of the game, Death To the Empress. Before heading to Dunwall Tower, players can stop off at Dr. Galvani's apartment. His apartment is near the Tower, but the doors are rigged with a deadly trap, so open with caution. The blueprint will be on the table in the laboratory. With all these blueprints found, Corvo and Emily have all they need to save the day.
