This teaches you how to make a 賈德奇特的能量來源, which can be used for quite a few interesting items, including a 飛天魔像號 and 皮耶, creating 賈德奇特的能量來源 will cost 10x 鬼鐵錠, this items creation is limited to once a day like its brethren, 雷鋼錠.

Just like 雷鋼筆記 (for Blacksmiths), this item is rewarded from a quest, 首席工程師賈德的日誌, this quest is started by picking up an dropped from 夷托卡, the same NPC that starts the 雷鋼錠 questline.

The quest (首席工程師賈德的日誌) is finally added in the latest PTR build, 夷托卡 drops the item () for engineers to start it. Next to a 賈德奇特的能量來源 you will get the 首席工程師賈德的日誌.

When opening this you will get 4 schematics:

Schematic: Advances Refridgeration Unit
Schematic: Pierre
Schematic: Sky Claw
Schematic: Stabilized Lightning Source

Happy crafting!

Just killed Itoka on PTR with my 600 engineer and he dropped nothing. Is this a random drop from him?

You do not have to be level 90 to loot this item. I looted this on a level 88 toon (with 600 engineering).

評論來自 UlarnekIronclaw

This may seem obvious, but you can only loot this item if you have 600 engineering. You also do not have to be 90, and they drop from any enemies in Pandaria that drop items, not just silver.

*note* (I'm lvl 600 in both Engineering and Blacksmith) One thing I thought was odd was both the ingot scheme and the journal appeared red to me as if I wasn't level 600 (also lvl 90, not that it matters). They were both red and yet I could & did learn them! Got the scheme for the ingot first, then the journal. Both in 45 mins off trash in the vale.

I'm not a noob, but I sure feel like one cuz I can't figure why they were red to me. I'll be checking back for people's comments. Be nice pweeeze!

***********************************************************************************

My second lvl 600 engineer (wanted to be able to make both types of rocket mounts!) got his journal in about 20 mins. His journal was also red, but as with my first engineer was able to learn it and all recipes inside.

! WOOT ! only 29 more days for the new mounts ! WOOT !

This dropped for me three times in a row off mogu near the Ruins of Guo-Lai, in Vale of Eternal Blossoms. Coords appx 29,31. This book is said to drop off any mob in Pandaria, so I'm simply stating where it dropped for me, not the only place it drops.

If you are a 600+ engineer, learning this book teaches you five schematics, that let you create these items:

Jard's Peculiar Energy Source - Bind on Pickup. This material is required to make all the other items listed below. It requires 10 Ghost Iron Bar and is on a one day cooldown.
Pierre - rare pet, Bind on Pickup. Requires 15 Jard's Peculiar Energy Source and 15 Living Steel.
Rascal-Bot - rare pet, Bind on Pickup. Requires 15 Jard's Peculiar Energy Source and 15 Living Steel.
Advanced Refrigeration Unit - 36 Slot Cooking Bag, Bind on Equip. Requires 5 Jard's Peculiar Energy Source and 5 Living Steel.
Sky Golem - Epic Flying Mount, Requires Level 80 and Expert Riding. THIS MOUNT CAN BE SOLD, it is not bind on pickup. Requires 30 Jard's Peculiar Energy Source and 30 Living Steel. So for all of you (like me) who saved up 300 Ghost Iron Bar and 30 Living Steel in hopes of being able to make this mount the day of patch release, see you in 30 days.

Got this from a 谷之寶藏 that I looted from an 遠古郭萊貯物箱 in the hall of the serpent in guo-lai halls.

Is this item still dropping? Wowhead is saying no longer available to players.

評論來自 javierspn

Just logged in to confirm that apparently this can drop from ANY mob in Pandaria provide you have engineering 600+.

I got mine specifically by killing like 6 mobs at Townlong Steppes.

評論來自 TheManCalledZee

This website is wrong. This item has dropped for three alts, in rapid succession in the Vale of Eternal Blossoms for me today, September 22, 2016. It took 6-10 kills each time, which, at 100+ is a joke.

Schematic: Chief Engineer Jard's Journal is the new version of this item.

評論來自 Faeryin

As of 7.3, this item does still drop. Just picked it up in Vale of Eternal Blossoms from some Mogu. Not sure why wowhead says it's not available to players when clearly it is based on my xp and other posts before mine.

評論來自 ejlejl
