X-87型战斗电路
You will need 2-3 runs of the 诺莫瑞根 to get 50 items. It is easy, but will take 20-30 minutes.
Mechanical creatures are in the second part of the dungeon
To get to the 诺莫瑞根:

Horde players can use teleport in the 荆棘谷海角 from Grom'gol Base Camp You can use Dalaran portal to Karazhan and then fly. I'm showing this in my video.
Alliance players can use portal from Dalaran to 铁炉堡 and then just fly to the entrance

加固电路板
Both factions can use teleport in the Chamber of Guardian in Dalaran to the Wyrmrest Temple - Northrend
Or you can use 虫洞发生器：诺森德 if you have it

This one is insane if the droprate is not 100% and it is not a bug

Not 100% droprate or it is bugged
Killed him on 3 difficulties 12 times already. 3 times with 800 Engineering skill.
You need 2-nd player to help you with 迦拉卡斯
Average 2-men run takes 30 mins

魔能活塞稳定器
This one is just evil

Respawn time is 3-5 days
Drops boe gear, so ppl are farming him to sell this gear on AH
No easy server hops in Legion
He stands near the final chapter of the illidan storyline quest and there is always 5-10 ppl near this place. Not 40-50 yards away, but his spawn locations is objective of the Illidan storyline. lol
Not 100% droprate, haha. I hope that it is a bug.
Killed him 4 times on beta in august, 2 times with 800 skill

If you managed to find him on some server... (I doubt you will, but still;p) you can try to server hop, but you will have to recreate the party when you are near his spawn location. It bugged for me. I'm showing this in the video

This one is easy or maybe it was easy for me)
Both factions can use teleport in the Chamber of Guardian in Dalaran to the Wyrmrest Temple - Northrend
In ulduar you don't need to clear anything, just use the teleport to the mimiron room. You don't even need to kill the first boss 烈焰巨兽. I hope blizzard will include something like this for the 决战奥格瑞玛 part

Got this 9/8/2016 on live just by looting the boss, not salvaging the boss.

评论来自 Ainyan

Looted from boss in LFR on 9/9/2016.

评论来自 Thejasko

战斗行动预测数据库 has a good chance of dropping on lfr mode.
To enter lfr, talk to Lorewalker Han in Seat of Knowledge at the top of Mogu'Shan Palace and choose Gates of Retribution.

You will need to invite a friend to your group to kill Galakras, this is done by entering alone as stated above and then invite your friend/helper. Your friend will have to click "teleport to dungeon" on the little eye in the corner of the minimap and you're set :)

Can be looted solo, galakras is skippable by some classes.
Solo'd LFR, got 1 item off jugg, no databank.
Solo'd normal, got 2-3 items for each of 5 bosses but no databank.
Solo'd heroic, got only gold off 5 bosses but got databank.

评论来自 Westernharp1

I don't know if it is just me then. Went into RF with 2 of my guild-mates and we killed Galakras then the Iron Jug got it. Tried the week before and no luck on mythic.

评论来自 826041

So far LFR, Normal, and Heroic run... no drop. About to do mythic, but it's safe to say that this isn't a 100% drop.

Just finished on Mythic with two engineers in the group. It didn't drop. 0/4 this week.

评论来自 WeazelGames

So Apparently getting the 战斗行动预测数据库 is now Soloable!
I've done it super easy on my Demon Hunter, but it's very possible on others such as Warriors and Rogues haven't tried others.

I've made a Quick video showing the route I took to skip Galakras in LFR all the way to Juggernaut.

Was Lucky enough to loot the item on the same run :)

Dropped for me in LFR with one other in the group.

评论来自 kellyislame

Posting this screenshot to confirm my drop on normal difficulty since someone elsewhere on this page claimed he/she spoke with a GM who supposedly stated 战斗行动预测数据库 was only available in LFR difficulty. It took me 26 kills spread among all 4 difficulties before I finally saw this item drop on normal. Good luck fellow engineers!

评论来自 Vedrian

For those hunting this, as of patch 7.1, Galakras is now soloable by all classes. The cannons now stun longer, so you can hit Galakras twice before the stun expires. Much faster as well because you do not need to wait for the second tower.

评论来自 Comradical

Yep, run him probably about 20 times now (doing LFR, normal, and heroic every week). I want to complete my Reaves, but this level of RNG &*!@ery is really draining, and not fun for what is supposed to be a fun item.

评论来自 neosushi68

Ok, i believe i can confirm. That this thing only drops when your in the LFR Version of this Raid. I have tried so many times obtaining ith via "Normal" "Heroic" or "Mythic" never dropped. First time going through LFR it dropped.I was all by myself btw :)

Talk to Lorewalke Han

Maybe that helps some of you.

评论来自 dscc

It finally dropped for me, I had 4 attempts prior. ( not including 2 coin rolls tat yielded gold) I went and got all of the other pieces including 200 felslate, and brought with in my bags.

Last week I did, 10N 25H Mythic and LFR.

This week I simply went to the guy above Mog Vauilts and qued the LFR for the landing. ( the one after what happened in the valley....)

I'm not sure if having all of the necessary items first helped, but it sure didn't hurt this trip. ;)

Galakras is vey soloable. ( my advice; mark him with a raid icon, let both towers open up, keeping an eye on NPCs I'm a priest so if one got fracture I tossed a heal) Try to run up the tower once to clean it, so when you go for the cannon it's smooth. Thake your time, wait for Galakras to cycle around and pause and face you. hit with cannon, stun him. don't move, mash trigger on cannon again. ( hotkeying button 1 is a good idea) he'll eventually drop without you moving, just spamming cannon every 30 seconds.)

Good Luck.

评论来自 Sarthorius

With that low drop chance, blizz should make them BoA, instead of BoP, or BoE, to prevent those people trying to get their gold off ah from these then.

评论来自 Blackbeardswe

I lost kill count, might be one of those items that just happen to drop... in the next expansion.

评论来自 bugzy2341

The npc that gives you the LFR que is Lorewalker Han. He's the raid finder storyteller. The guy on the right.
The story you have to pick is the one that says, Gates of retribution. It leads you to start off at the two towers with the the dragon. Its the boss right before the one you need.

So, blow up the bombs next to the canons. They are on the beach. once they are all blown up, the boat shows up with the guy who starts the attack. Talk to him and it starts. 2 or 3 waves of mobs come at you before you can run up into one of the towers, where you kill all of the mobs in the tower before jumping into the cannon on top of the tower. 2 or 3 hits on the dragon from the tower cannon and he's down. then jump down and kill him.. (I take the left tower)

Im telling you how to get it started in case you have never run siege of ogrimar before.

Then just run to where the jauggernut is and kill him. Its a scorpion looking boss.

I had no idea where to get the LFR que, and no one had stated how to get into que, so im posting it here.

I didnt get the item I needed on LFR, Normal, or Heroic, yet. This is patch 7.1.5. just so you know you can do the LFR even though it was a few expansions ago that the LFR came out.. 1-27-2017

评论来自 acidicmantis

15 times solo on Normal on different chars and it didn't drop. same 800 skill, items in bags etc

first time on LFR after talking to Han at seat of knowledge and it dropped.

评论来自 Ejdl

Ran 3 times LFR different weeks and no drop.
I have no idea if it had something to do with it but this time i spawned Reaves before i engaged boss and this time it dropped.
It could be just luck but it's worth a shot.

评论来自 cryptid420

Just got this item my first try, though the other items took quite a few attempts

评论来自 ToriaURU

Dropped for me today on mythic difficulty. Wasn't looking for it and came here to find out what it was for.

评论来自 DrummerKane

I've tried to get this item ever since it became available and still nothing....very frustrating.

评论来自 voltrain

I ran this on normal and it didn't drop, came here and saw LFR might be a good option. First time doing the LFR, it dropped.

评论来自 irishbloke

that drop chance 0.46 is worse than most of the mounts that drop of bosses,isnt it? why put this as part of of a profession unless its meant to be a time-sink?

评论来自 HarunShahab

Why would they make an item used for one recipe, drop from one boss that you can only kill once per week? less than 1% drop rate?
is this an invincible mount?
Stupid.

评论来自 texanrogue

Wow I can't believe it. I've been farming for 3 months (I know not as long as some of you) but after reading the comments I decided to do LFR by talking to the panda guy and sure enough it dropped for me today :)

评论来自 Anamour

Ran normal 10 man no drop. Dropped 1st run of LFR, see comments below on how to do this. Still seems the best way to acquire this item

评论来自 Darmonevil

The listed drop rate means little to nothing because every single kill counts towards the total attempts but only engineers (and possibly only engineers with the recipe) can loot this. It is probably much high much higher than what is listed but there is no way to be certain.

评论来自 jormundgard

I've been doing this on LFR for weeks and still no drop. I don't know what's going on with this item, but it's not as simple as using LFR.

评论来自 egephart

After I don't know how many attempts....I finally got mine to drop. So it DOES EXIST!

评论来自 KKthx

Finally got this the other day! I had acquired all of the other mats during the past year (earlier in the year) for the Reaves Module: Piloted Combat Mode and just had this one to go. I hadn't tried super hard to farm this every week... just did a weekly LFR on weeks that I would remember to. By the time I had this drop, I had a total of 7 kills on LFR and 3 kills on flex with no luck.

A friend happened to be clearing both Normal, Heroic, and Mythic SoO this week so I tagged along for the Iron Juggernaut kills. We did Mythic, no luck... Heroic, no luck... but on our last kill on normal... LUCK!

It sounds like other people have had success with it dropping on all difficulties, so I wouldn't take this as "Only normal works!"... just thought I'd share that normal DOES work :)

评论来自 Tadewing

Dropped on normal mode. 2 tries.

评论来自 Naj4

Just got one, randomly doing it on mythic ^^

评论来自 Sumudan

Killed it today with my 120 shaman on normal difficulty who is not an engineer anymore oO

评论来自 brudarek

finally got it, from LFR, after way too many tries.

评论来自 MapleWarrior

i am not, by any means, bragging, and this may have simply been dumb luck, but I got this drop today on a toon that was soloing Siege for the first time.

Possibly, the drop rate has increased as of BfA.

评论来自 Mordane

Hadn't even looked to make this,...so thought I'd have a look at it now (better late than never). Ran it on Mythic then Normal,...and lastly Heroic. And it dropped on Heroic. :) Now just need the last piece from Ulduar.

评论来自 irishbloke

Tried to get this item in non LFR (normal,heroic, mythic) and it didnt drop but dropped first time in LFR
