I did this at level 36 on my rogue stealthing through most of it -- the stealth helped a lot due to the clumpy mobs.

I followed the back door strat and it worked perfectly. I had to beat up a few mobs to get access and wait for pats to clean out for awhile, but eventually I got it.

Very easy using the back door -- saved a lot of time. Stay on the ground floor and the side passages have the access panel at the entry.

on using the Security Delta card for your recipe for the Discombobulator Ray, ...the recipe is learnt automatically to your engineering recipe inventory, IT IS NOT A RECIPE RECEIVED IN YOUR BAGS!! check your recipes you will see it there

評論來自 shamanlover

This item permits engineers with the otherwise required skills to learn the Discombobulator Ray recipe from the Matrix Punchograph 3005-B, as well as learning the recipe for the Minor Recombobulator from the Matrix Punchograph 3005-D. Note, however, that having the associated punchcards is still a necessity to access the punchographs.

Got this off a Mechano-Flamewalker.

I was disappointed to find that these can't be stored in a toolbox.

From the very last boss, if you head back up the passage, there will be a small hall leading off to the right to another big. It's right there at the end of that passage.

Do you need a quest to pick this up? Or is it just to farm?

Edit: You do not need the quest to pick this item up. Got mine a second ago from a Mechano-Flamewalker. Sadly it's only in my bag :S. I can't find the recepie in my engineering skill and it does not say i learned anything. I can't click it and I am 100% sure I got this exact card and not the recepie. Help please!

Edit: Found it. I just needed to go to "Matrix Punchograph 3005-D" which can be found in the lower Engineering Labs once I got the card. Yet for some reason the card was still in my bag :S. Sent it to a friend who I know needs the recepie as well :D

As far as I know this item is a bit unique in the game. It is essentially a key that "unlocks" access to engineering plans, but the key is not destroyed in the process. This means you can pass this item to a friend or sell it in the auction house for other engineers to use in the same way. This is good for recipe collectors. I know of no other items that are like this.

The drop rate is low (under 5%), but not unreasonable; and drops from many mobs in the same area. It's quite likely you will see one or more of these drop in a run.

Does anyone know if this card still drops? I have done several runs of Gnomeregan but haven't received a card yet. Also, the loot table shows this is a RED item for both Alliance and Horde.. help please

i just looted this today so it still exists

To get the 退化射線, use this item on the Matrix Punchograph D, which is located on the ground floor in the ENGINEERING LABS of Gnomeregan. It is on the floor below the Crowd Pummeler 9-60. It will be automatically learned through your engineering.

You must have a Security DELTA Data Access Card in your bags to to use the Matrix Punchograph D to learn the Discombubulator Ray schematic. The drop rate on the Security DELTA Data Access Card is low enough to warrant buying one on the auction house to ensure access to the schematic. You can usually find one for around one gold if you plan ahead.

Pug groups generally avoid the lab wing where the 矩陣式打孔電腦3005-D is located. You may have to coax you group, get friends to help you, or solo later.

As mentioned elsewhere, the Matrix Punchograph D teaches you the schematic, you do not get a schematic in your inventory. However, the 結構圖：退化射線 item is also available as a rare drop (~ 0.5%) from the final boss, 機電師瑟瑪普拉格. The schematic item can be sold for quite a bit; so it is worth learning the schematic from the Matrix Punchograph D, even if you get the schematic item.

If you are in the instance farming engineering schematics, be sure to also get 結構圖：炸彈寵物 and 結構圖：發條娃娃. Mekengineer Thermaplugg is worth killing even if you already have the bombling schematic, as he drops several engineering schematics, albeit at a low drop rate.

FYI for old timers, the punch cards are no longer required nor generally available. The White Punch Cards no longer drop, the mobs that dropped them have been replaced, and the Matrix Punchograph A machines are gone. The Matrix Punchograph D will teach Discombubulator Ray schematic without a punchcard. The Matrix Punchograph B no longer teaches the Minor Recombobulator schematic. The 結構圖：初級淨化器 is now available to both factions.

Added June 4, 2016:

The card is not consumed on use. You can share it, sell it when you're done, or whatever. A guild can keep a loaner copy, as long as everyone understands to return it when they're done with it and not just toss it.

The use of the punch card on the Matrix Punchograph D to learn the Discombubulator Ray schematic has an Engineering skill requirement around 150 or 160. The card is not consumed, you can safely try it and return later if it fails.

Does this even drop anymore? Must have gone through several hundred of the listed drop mobs. Not one.

評論來自 Phaythe

Confirm this still drops. Seven runs through the day, last run this dropped twice, once from Mechano-Frost Walker, then from Peacekeeper Security Suit. Confirm this still only works on the last set of access panels, the "D" panel, and the schematic "Discombobulator Ray" automatically goes into your engineering book.

Also confirm, as a Horde, the Goblin transporter at Grom'gol Base in Northern Strangelthorn still works, drops you off at another transporter directly inside the entrance of Gnomeregan. Any entrance walking back out takes you right back to Grom'gol.

Just dropped now for me. So yes, still ingame (07/18/2016)

Just wanted to let anyone know it just dropped May 25th, 2018.

Dropped on January 20, 2019.

The 秘密資料存取卡 will not be consumed upon use so if you got several engineers that needs the schematic for 退化射線, you can send it to an alt or sell it back to the Auction house for some gold.

The recipes associated with the Security DELTA Data Access Card can no longer be obtained through it. It is worthless. Instead, the related recipes can be found as follows:

Also of note, the Prismatic Punchcard questline no longer appears to be in the game. If it still exists, the starting point is based off a 3% drop chance of the White Punch Card from a rare spawn in New Tinkertown (the Gnome starting area).

This still drops in Dragonflight. I successfully acquired my 退化射線 via the 矩陣式打孔電腦3005-D today, then sent my 秘密資料存取卡 to an alt.

評論來自 TorbIsThicc

Checking in from 11.0.2 to let others know it still drops. Probably just easier to buy off the AH considering how cheap it goes for.
