This must be one of the most old WoW related things that we do not seem to be certain about what it actually is in WoW.
These are what our clues seem to be
The item always seem to be a vial of some sort.
Vials can contain liquids or solids small enough to fit in, like powder or small beads.
It does not seem to be something collected from the body of the troll killed as an emote some troll NPC do when agroed is “I am going to make you into mojo!”.
So it probably means that it is made using something physical of spiritual part of some slain person.
At the same time there is the flavor text of the Massive Mojo that says “More Mojo than any one troll should have.” It seem to suggest that it is both something that varies with potency and quantity in its container or in the body of such a creature
The players can use it for few things like for crafting magical robes and some potion.
With all these things considered, has anyone decided what WoW’s mojo is supposed to be? Does it have some particular form or is it just a convenient way to name some magical things related to the troll tradition?
i assume its troll version of chinese Qi
In traditional Chinese culture, qi or ch’i [qì] is believed to be a vital force forming part of any living entity. Qi translates as “air” and figuratively as “material energy”, “life force”, or "energy flow
I like to think of Mojo as the troll term for Chi, but Troll mojo is different from all other race’s Chi, in that it doesn’t present in a misty/gusty form and is denser and stickier, hence why it can be bottled.
Why is this the case? Maybe it’s something to do with the fact that Troll have loa-blessed regeneration, so quite a direct racial tie to the wild gods (who come from Spirit -> Chi) so it means their Chi is “heavily saturated” or something.
