4. Finding the Praxis Kits

Praxis Locations in DX3

=====================================================================
- Detroit
Detroit Downtown Apartments, third floor of the westmost building (the one with the security gate), inside an illegal augmentation 'chopshop' with a level 5 security door (code to get in: 2356), then hack the level 2 terminal (8221), then hack the level 1 computer (atcod) for the final code (3663) into the area with the kit).
In the sewers beneath Derelict Row. These are accessible from a manhole cover in the bushes along the wall on the right side of the entrance to the first building, or from a manhole in the construction site below the antenna. The kit is in a hidden area accessible by breaking through a wall. Location of wall is shown by Jensen icon in the image. (ie. the white-bluish arrow at the east end of the map. Enlarge the image for clarity.)

1st visit
Inside a box shortly after exiting an elevator in the Sarif Industries Milwaukee Junction factory. It's fairly hard to miss as it's highly visible and right in the player's path, and the Augmentation tutorial even pops up at that time to discuss Praxis kits. However, if you don't collect it you will miss the chance, as you'll never get to return to the factory later. One may backtrack to this point so long as they have not yet left the factory by means of talking to Faridah Malik.
LIMB clinic - two can be bought for 5000 credits each. (On his first visit to the LIMB clinic, Adam is given 5000 credits to spend, effectively making the first Praxis kit free if he chooses to buy one.)

2nd visit
One in Isaias Sandoval's apartment across the street from Adam's place and is only available if Zeke Sanders survived the encounter in Milwaukee Junction. Go to the street alley in front of Adam's place. Climb up the ladder in the alleyway until you reach the building's entrance. Afterwards, walk to your right to find an open gate that was not available before. The praxis kit is in the main room, next to a dead guard. The kit is connected to two EMP mines (hidden under the dead guard) that should be disconnected before grabbing the kit (if the player does not have EMP resistance). Note that the trap will not be there if Zeke Sanders has been killed prior to this point; as long as he is alive and conscious, regardless of whether he is jailed or set free, the trap and the Praxis kit, will be there. If you kill or render him unconscious (whilst in the apartment and before disturbing the trap), the trap will be automatically disarmed.
LIMB clinic - two can be bought for 5000 credits each.


- Hengsha
Behind a breakable wall in the sewers below the Hung Hua Hotel in Hengsha, (From the ladder to the hotel go left and wall is opposite a stack of matresses).
In the bottom of an elevator shaft in Hengsha Court Gardens. (Access from the southwest roof via a hackable door or breakable wall or through the upper floor vent shaft on the left of the elevator as you exit.)

1st visit
LIMB clinic - two can be bought for 5000 credits each.
From Bobby Bao - the bartender at The Hive. Either search his corpse, or during his side quest. Convince Jaya to make the monthly payment, or pay 5000 credits yourself. Note: after completing the sidequest, you can punch out Bobby Bao to get your 5000 credits back. Just be ready to run out of there in a hurry...
A reward from Malik after doing the side mission for her.
On the second floor of the Tai Yong Medical building in the Upper City Labs, in a desk drawer in a medical room above the Lee Geng Lab. (Laboratory B-2). Look for an out-of-the-way door on the catwalk above the large open lab.

2nd visit
LIMB clinic - two can be bought for 5000 credits each.
On your second visit to Hengsha, a reward from Doctor Wing's side quest in the LIMB clinic.

- Montreal
Inside a drawer, in one of the cubicles in the center of the Picus TV newsroom, on the same floor as the room 404.

Singapore - Omega Ranch
None.


- Panchaea
There is a LIMB clinic hidden behind a vending machine that can be moved. Two Praxis kits can be purchased there for 5000 credits each. After completing your goal in the control tower and riding back down the elevator, pass through the door that has newly been opened. In the area labeled "Ring Section" on your map, there's a side path with a vending machine jamming a door. You will likely need the strength augmentation to move the vending machine and get in.
=====================================================================


=====================================================================
The Missing Link
Even though the story of The Missing Link DLC is embedded into the main plot, the Praxis kits earned during it do not carry over to main game. For this reason, the Praxis kits found during The Missing Link are listed separately.


- Hei Zhen Zhu
Brig, Floor 4
1-7: Special "Praxis case" near Adam's body armor with 7 Praxis kits inside.


- Aft Section, Floor 4
8: Container with a Praxis case inside, it can be seen through the window of the control room on Floor. Can be reached from 1) Floor 4 by breaking the fragile wall of the container (it will kill the soldier standing behind it), 2) Floor -1 by stacking 2 crates or with an upgraded jump.


- Rifleman Bank Station, part I
Loading Bay 1
9: On top of the cargo crane holding the blue container.

Admin Sector, Floor -1
10: By default there is a single Praxis kit for sale in Garvin Quinn's shop. Good idea to create a new save game just before talking to him. Activating the Social Enhancer augmentation and using Omega pheromones will drop the price of the standard stock Praxis kit from 5000 to 2500 credits, however you will not be able to obtain kit 11 or 12.
11 & 12: Activating the Social Enhancer augmentation and using Alpha pheromones will convince Quinn to open a completely new 'special' stock with 2 additional Praxis kits, among other things. Special stock replaces the standard, so buy Praxis kit #10 before you convince him. Kits 10, 11 and 12 will be discounted to 3750 credits instead of 5000 if you have completed the Acceptable Losses sidequest on the Hei Zhen Zhu.

Detention Camp
13: On top of the mainframe room in the center of Detention Block B. It can be reached by jumping from the balcony on Floor 3 near the typhoon turret. The turret can be destroyed with an EMP grenade without causing alarm. To make it to the platform you have to sprint before jumping. It's a bit tricky, but doable after a few tries, even without the jump enhancement augmentation. To get down again just shoot the glass ceiling and fall down to the mainframe room.

Restricted Wing
14: Inside the drawer right next to Dr. Tiffany Kavanagh.


- Rifleman Bank Station, part II
Interrogation Wing
15: On the topmost platform of the elevator shaft. Can be reached either using the Jump Enhancement leg augmentation or by stacking two heavy crates with Move/Throw Heavy Objects augmentation.

Maintenance Level
16: Near the safe inside Quinn's shop.

5. Praxis Secret - XP/Stop Worm/Nuke Virus/Credits Glitch! (Part 1-2: DX3)

=====================================================================
This Secret will show you how to gain lots XP/Credits/Stop & Nuke Viruses in DX3!

All you need is a device where you can hack the red "trace symbol". By hacking the trace symbol instead of the normal green access symbol you will gain extra experience. To make this even faster you should search for a level 1 or level 2 device and hack the red symbol on the same way.

The higher the security level of the hacked device, the higher is your XP reward.
Save your game when you found a good spot. Hack the red symbol and load your save data after the successful hack (while the screen with the XP reward is shown).
Hack the same object over and over again and you will always get more XP/Credits/Stop or Nuke Viruses.
Keep in mind: You will get the final XP bonus only once;
the single hacks don't sum up and you can't hack the device again.

Steps to gaining Praxis Kits in this Secret:
1. Save your Game after you found a device where you can hack the red "trace symbol".
2. Hack the Device. [Use Nukes to hack faster]
3. Load your game [Do NOT leave the Device]
4. Repeat the Hack & Keep Loading your Data
5. Leave the device when you've earned enough XP/Credits/Stop & Nuke Viruses.

Hint:
If your playing the PC version of DX3, you can use the Quicksave/Quickload Feature to perform Steps 1-4.

7. Your Questions

Please let me know what you think of this Guide on how to get Praxis Kits & let me know if I missed any XP Grinding Spots.

[fishhooks]

Someone may already have mentioned this, but just in case...

Best place I found is the safe in Seurat's (gun merchant) bedroom in Detroit Apartments. Level 4 safe, with 300XP, 300c, 1 Nuke Virus and 1 Stop Worm Virus. With 10 nuke viruses in inventory, you can hack thru everything, then reload save. 100 times means...well...do the math. Best place to get a lot of everything quickly.

[frederickedward 1]

door codes,where do you find other then e-mail

[Hellshake Yano]

I found a quick, easy Lv. 3 PC to hack in the missing link DLC, gives 200XP. You can acess it from a vent in Burke's office. (the room you get his eye in. )
It takes only 3 nodes to capture (including the trace node) and they're all easy ones (lvl 3, lvl 2, lvl 3)
This means you only need 2 nukes to capture it undetected. 3 if you want to nuke the trace too.

[Hellshake Yano]

(steam comments need an edit button, I've had to copy, delete, paste this a few times to add the bits that occurred to me after I posted it...)

Ah, nevermind, I see what it was.
The XP earned doesn't show up til you're done and you close the computer console. It just stacks the data looter XP over and over each time you do the trick, then gives all of it to you at once when you're done. (Just curious, but do you get the regular hacking XP to stack too, or just the stuff from data stores?)

For anyone else I'll just add: you need 4 nuke viruses (virii?) to hack the computer in Jensen's office with no chance of being detected. (not a big deal but I just thought I'd add it :P)

[Hellshake Yano]

By the way, I can't seem to get the hacking XP trick to work.
I'm quicksaving before interacting with the computer, hacking it using the trace node, and then quickloading on the window that pops up saying what I got from the datastores. I never leave the computer but I still seem to end up with the same amount of XP I had before hacking after loading the quicksave.

[VolnuttHeroP64]

thank you.

[Hellshake Yano]

Incredible guide, very well done. (Also I appreciate the To The Moon name/avatar you've got )

[Darth Dangermouse]

As lexilogo said, the missing link now included in the main game.

[VolnuttHeroP64]

Not to mention Grinding Spots.

[Sdoots]

This guide should be much higher rated than it is. Thanks for the Praxis Kit locations! I like to explore each area for them myself, and then once I've done everything I can think of, I check here to see what I might have missed.
