Well, this is a first. In Legion (well, technically patch 7.0) Hunters will be able to venture into Siege of Orgrimmar and gather parts to make their very own Iron Juggernaut pet — in four different colors! To fully discover all the ins and outs of this taming challenge took many hours of searching around SoO, and the rest of Azeroth for that matter. I spent most of the time searching around with Valnaaros from the Petopia forums.
One of the parts needed turned out to be extremely well hidden, and when we didn’t see it on first inspection we assumed it was found elsewhere. After visiting every gnomish and goblin type area in WoW, we finally went back to SoO and found the missing piece. If you want to discover all this for yourself, skip the guide section below.
Note: There is currently a bug with these where you cannot tame them below level 120. Wait until you’re 120 before you spawn them! But if you used it before 120 and got the “too high level” message then you should be able to make a ticket and ask for it to be restored since this is a bug.
