DISCLAIMER - This post will be updated as more information becomes available with Legion datamining. All of the below information is subject to change!

What is Batterie de Reeves?

Batterie de Reeves, an Engineering item coming in Legion can be crafted at skill level 700. It will be a Engineering multipurpose helper!

How do I craft Batterie de Reeves?

The quest La touche finale, part of a chain of Engineering quests, grants 1 Batterie de Reeves as a reward and teaches you Schéma : Batterie de Reeves.
Batterie de Reeves is the basic item. At present is soulbound, and stacks to 20 - as such it is a consumable item for Engineers alone.

The materials to craft 1 Batterie de Reeves is a meager 5 Gangreschiste.

What can Batterie de Reeves do?

A number of modules can be also crafted by Engineers. Note that they are Bind-on-Pickup. These modules "supercharge" Reaves to grant him certain useful abilities!

For example, the follow-up quest to La touche finale is Modifications modulaires, which has you create and install a Module de Reeves : mode Distribution d'en-cas on Reaves, and as a reward you learn the Schémas : Module de Reeves, mode Réparations.
Using any module will unlock that ability for all future Batterie de Reeves that you drop. As you use more modules, your Batterie de Reeves will have more options available when dropped.
Reaves isn't stationary when summoned - he will follow you around until he despawns after 10 minutes.
Once you set a mode for Batterie de Reeves, he is "locked" to that mode; you must drop another to use a different function.
There is a 90 second cooldown to use Reaves.

Below is a list of various modules that have been unearthed so far!

Module de Reeves : mode Réparations
Gives Reaves the ability to Repair gear.
Module de Reeves : mode Détection des échecs
Gives Reaves the ability to resurrect players after a wipe, similar to Pylône de détection des échecs.
Module de Reeves : mode Générateur de tunnel spatiotemporel
Gives Reaves the ability to teleport players elsewhere (similar to Centrifugeuse spatiotemporelle and other Engineering Wormhole items).
Module de Reeves : mode Bling-bling
Gives Reaves the ability to act as a Blingtron, and grant gifts!
Module de Reeves : mode Combat piloté
Gives Reaves the ability to be controlled to combat other mechanicals.
Module de Reeves : mode Feux d'artifice
Gives Reaves the ability to put on a Fireworks display.
Module de Reeves : mode Distribution d'en-cas
Turns Reaves an interactable "feast" - all party/raid members that eat this feast gain a +225 versatility buff.

Commentaire de Aelriana

This quest has you doing errands within Dalaran where you basically pickup an item, and then run back to Didi to let her test it. It's performed in the following order:

Run to the Jewelcrafters and talk to Tiffany Cartier to get the Diamond, then run back to Didi.

Run to the Alchemists and talk to Deucus Valdera (the Undead) to get the potion, then run back to Didi.

Run to the inn and talk to Bonegrim who stands in the bar and tells you he won't give you get Core unless you steal a jewel for him.

Run upstairs and tell Catriona she's needed downstairs, and when she's gone you steal her Jewel which is next to her bed.

Run back downstairs and talk to Bonegrim to trade the jewel for the core, and then finally return to Didi.

Commentaire de varenne

In this quest we are building the Batterie de Reeves

Speak with the Jewelcrafting Supplies vendor Tiffany Kartier
/way 38.7, 35.0 Tiffany Cartier
Return back to Didi la Clé à molette and he will say that this doesn't work
Try alchemy Deucus Valdera
/way 40.0, 30.1 Deucus Valdera
Return back to Didi la Clé à molette and he will say that we need Noyau imprégné d'énergie gangrenée
Go to the Lendgerdemain Lounge and find Os-Sinistre
Orc is near the bar
/way 48 38 Bonegrim
He asks you to steel the red jewel upstairs, lol
Stairs up are near the right entrance
Joyau de Catriona is in the first room to the right
You can take Joyau de Catriona from it but first tell Catriona Macrae that someone is looking for her downstairs, haha
Give the Joyau de Catriona to the Os-Sinistre and he gives you Noyau imprégné d'énergie gangrenée
Return back to Didi la Clé à molette . Success!
We can use Reaves now, just need to craft some Batterie de Reeves

Here is my main Ingénieur de la Légion post.
You can find more info about the profession there.

Always the Last Thing quest video: https://www.youtube.com/watch?v=Tl9sFzxaVKk

So at this point you are probably thinking what is Batterie de Reeves and how it works.

Craft Batterie de Reeves for 5 Gangreschiste
Use the battary and it will summon Reeves

Initially he is not usefull, but you can install several modules on him
Here is compiled info about all the modules => Ingénieur de la Légion

1 Batterie de Reeves Summons Reeves https://www.youtube.com/watch?v=eAzRErCHNfc
2 Module de Reeves : mode Combat piloté More info
Module de Reeves : mode Bling-bling More info https://www.youtube.com/watch?v=9MSKekCjiNg
4 Module de saccage-o-bot : mode Générateur de tunnel spatiotemporel Don’t have a Schematic (Not from quest)
Module de Reeves : mode Distribution d’en-cas Similar to Festin copieux but gives 225 versatility https://www.youtube.com/watch?v=FP7Wy4FZMmI
6 Module de Reeves : mode Réparations Same as Auto-marteau https://www.youtube.com/watch?v=WghKzvuKQyQ
7 Module de Reeves : mode Feux d’artifice More info https://www.youtube.com/watch?v=M8KlFJrQhag
8 Module de Reeves : mode Détection des échecs Same as Pylône de détection des échecs https://www.youtube.com/watch?v=uvHn4Sl9LrA

How modes work:

Craft some module once

Install it by speaking with Reeves
Now you can activate it every time you summon the Reeves
Can activate only one mode per Batterie de Reeves use
But Batterie de Reeves has short CD

Full quest chain under the spoiler.
You can see how far you are in the storyline.
Right now wowhead doesn't have all the quests. Engineering was so heavily gated, that no one really tested it on Beta. I'll update links after wowhead DB update

Commentaire de fsomalia
I will NOT finish this quest. Blizzard, I'm not a thief.

Commentaire de LeaNoodles
Can't we just, like, buy the jewel from Catriona? Jeez, Bliz, this is flat-out thievery!

Commentaire de Allara
If you, like me, are unable to pick up the jewel after Catriona has left, you may also be on the Jewelcrafting quest Le sens du détail. Finish that quest without dropping this one, and you'll be able to pick up the jewel.

Commentaire de Clinea
I can't get myself to steal the jewel from Catriona, I hope they let us pay her back next patch or something :P

Commentaire de DaylarFarshot
Greetings!

If you are like me and had moved onto the next quest and used your Reaves battery by accident but suddenly you can't make Reaves any more and yer wondering how the heck you can progress and you made it here finding out you already did the quest to get the recipe to make Reaves, well look no further.

Go back to the Engineering building in Dalaran and talk to Hobart Grapplehammer, goto his 2nd page of stuff and spend 800 gold on Forgotten Schematics of the Broken Isle. Use said item then open up your engineering panel and viola you can make Reaves Batteries once again.

Hope this helps someone else that ran into the same situation as I did.

Commentaire de rogermw
They misspelled "legerdemain".

Commentaire de Koorisin
Anyone have issues completing this quest? I cannot pick up the red jewel to give to trade for the fel-infused Core.
Ive abandoned and restarted the quest but i cannot pick the damn thing up to give to bonegrim for the fel-infused core please advise anyone

Commentaire de 1750503
I felt so bad for stealing the gem :C

Commentaire de lybrewa
Do you have to be level 100+ to get this quest? I finished The Missing Pieces but Always the Last Thing isn't being offered at level 98.

Commentaire de Emalethx2
My engineer is a rogue - think this quest was made for me... my pally frowned at her though :p

Commentaire de Pneumonia
After trying TWICE to get the jewel with her in the room, been told "Excuse me, but that's my jewel. Could you please leave it alone" each time, and then sending her downstairs; I think she will now it was me who took it >.<

Commentaire de Apollomantis
So, in my quest to gain the discount Jeeves, I did all the quests for the ENTIRE engineering chain, in which it seem that being able to craft reaves batteries is either bugged, or I didn't do some internal trigger. As following a suggestion made by another commenter, buying the forgotten schematics of the broken isles did indeed add the reaves battery to my engineering journal, but it also added bling mode which required 100 legion engineering to learn, which I don't have.

I'm not sure what went wrong or why I didn't have it before given I did everything in theory, yet it just seems like its still very buggy and needs to be fixed honestly.

Commentaire de UnciaAmethice
Can't do this quest for a while now. My mage has the quest. I can lure Catriona out of the room, but the gem itself isn't interactable so I can't take it.

Have done the usual removing addons, abandoning and retaking the quest etc, and the character isn't a Jewelcrafter so that quest isn't interfering either.

Description

Bon, j’ai presque terminé. J’ai ajouté que’ques boulons par-ci par-là et un nouveau boîtier pour l’alimentation.

Le hic, c’est qu’aucune des batteries que j’ai là ne marche. Va falloir en bricoler une nouvelle.

Et pour ça, j’vais avoir besoin d’votre aide, <nom>. Commençons par essayer avec une gemme chargée. Y en a à la joaillerie, plus bas.
