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

This is the last in a chain of Engineering quests that will teach you to create Schematics: Reaves Module: Repair Mode, an upgrade for Reaves Battery, a new multipurpose Engineering helper! Reaves Battery can be crafted at skill level 700.

This quest requires level 102 and the Engineering skill to pick up and complete.

What is Reaves Battery?

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

How do I craft Reaves Battery?

The quest Always the Last Thing, part of a chain of Engineering quests, grants 1 Reaves Battery as a reward and teaches you Schematic: Reaves Battery.
Reaves Battery 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 Reaves Battery is a meager 5 Felslate.

What can Reaves Battery 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 Always the Last Thing is Modular Modifications, which has you create and install a Reaves Module: Snack Distribution Mode on Reaves, and as a reward you learn the Schematics: Reaves Module: Repair Mode.
Using any module will unlock that ability for all future Reaves Battery that you drop. As you use more modules, your Reaves Battery 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 Reaves Battery, 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!

Reaves Module: Repair Mode
Gives Reaves the ability to Repair gear.
Reaves Module: Failure Detection Mode
Gives Reaves the ability to resurrect players after a wipe, similar to Failure Detection Pylon.
Reaves Module: Wormhole Generator Mode
Gives Reaves the ability to teleport players elsewhere (similar to Wormhole Centrifuge and other Engineering Wormhole items).
Reaves Module: Bling Mode
Gives Reaves the ability to act as a Blingtron, and grant gifts!
Reaves Module: Piloted Combat Mode
Gives Reaves the ability to be controlled to combat other mechanicals.
Reaves Module: Fireworks Display Mode
Gives Reaves the ability to put on a Fireworks display.
Reaves Module: Snack Distribution Mode
Turns Reaves an interactable "feast" - all party/raid members that eat this feast gain a +225 versatility buff.

Comment by varenne

This quest was the biggest blocker for engineering on beta.
You had to craft Reaves Module: Snack Distribution Mode = 5xHearty Feast for this.
TheHearty Feast recipe is Nomi's Test Kitchen discovery.

Now you need to bring food and not feast

Here is my main Legion Engineer post.
You can find more info about the profession there.

Modular Modifications quest video: https://www.youtube.com/watch?v=59UDLPfrot0

So at this point you are probably thinking what is Schematics: Reaves Module: Repair Mode and how it works.
First of all you dont need any skill. Everything can be done on 1 engineering skill.

Initially he is not usefull, but you can install several modules on him
Here is compiled info about all the modules => Legion Engineer

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

Comment by Loanel
This quest blocks the entire questchain for engineers in Legion. Nobody on my realm has the recipe for this food, and it is tied to those random cooking work orders. I have 770/800 skill thanks to gunpowder charges and i can't even get gunshoes. I wish they required some easier to get foods instead of one of the rare ones right off the bat.

EDIT: wow that was fast, Blizzard sneaky patched it 8h after my post, now instead of a Hearty Feast it requires 20 of Big Gamy Ribs, Wildfowl Egg, Highmountain Salmon and Black Barracuda

Comment by BeeRizzzle
Do you have to reapply everytime you want to use snack distrubution? ie make tons of the modules...

Comment by 1076247
I guess I'll get around to leveling Eng later on. The requirments to continue, this early in the quest chain, are ridiculous.

Comment by Boxofbeer
To craft Reaves Module: Snack Distribution Mode you have to obtain following materials:
80 x Felslate
20 x Big Gamy Ribs
20 x Wildfowl Egg
20 x Highmountain Salmon
20 x Black Barracuda

To craft Reaves Battery you have to obtain 5 x Felslate. Summon Reaves and then use Reaves Module: Snack Distribution Mode to switch it in to Snack Distribution Mode. Also, if you will eat, you'll get a buff.

After the quest you'll learn how to craft:
Reaves Module: Repair Mode
Reaves Module: Snack Distribution Mode

Comment by kumakitsu
If you made the module and applied it without having the quest, you can no longer progress in the engineering quest line. Put in a petition and pray, I guess!

Comment by drooidmadness
I am up to this quest atm on my rogue, I summoned the reaves and then relised I needed to craft the module. So I logged to my alt grabbed the mats and sent them to my rogue, crafted the item then went to summon reaves only to relise reaves was a 1 time summon. So I discarded the quest and retook it, hoping that she would give me another reaves but she doesn't. Shut down the game, turned off addons, retook quest. Nothing works.

Contacted Blizz and all they say is reload UI, discard and retake the quest, turn off addons and try again, check wowhead.....All the normal copy paste answers because they are "busy with a high volume..." Well blizz if you bothered to help you customers maybe there wouldn't be such a high volume in the first place....Going to repost the ticket until i get a proper reply.

Comment by ChaosCheese
This quest bugged out on me. Upon completing "Always the Last thing," it did NOT give me the schematics for the Reaves Battery, or the Snack distribution. This was very confusing because it looked like it wanted me to craft the Snack Mode in order to complete the quest to give me the recipe for the snack mode.

If this happens, DO NOT USE THE BATTERY, just abandon the quest and pick it up again until you get Snack Mode. (Doing this multiple times might work to get both). I used my battery already so if you do, you can get the "Forgotten Schematics of the Broken Isles," from Hobart Grapplehammeer right next to the quest giver. This should teach you to make the battery.

It took me 20 minutes to figure out what went wrong, small indie gam devs :(

Comment by Sujing
If you're like me and summoned Reaves prematurely, just make a new Reaves battery and complete the quest.

Links

Modular Modifications

Create a Reaves Module: Snack Distribution Mode. Then summon Reaves and install it into him.

	Create a Reaves Module: Snack Distribution Mode (1)
	Summon Reaves and apply the module (1)

Description

Now that we got this baby running, let's give it some cool abilities.

When I was fixing Reaves up, I installed a module port onto his motherboard. This will allow us to upload anything we want.

I'll teach you one of my module designs and you install it on Reaves.
