And most of it is consumed by The World Soul within as sustenance. It is now referred to as Chi by monks and pandarens. The disappearance of Spirit causes an imbalance in Azeroth & make the other elemental lords to go to war with each other.
Any speculation what will happen to this elemental spirit group when Azeroth becomes Titan (maybe in the next expac)? Is there a former Elemental Lord of Spirit (or Spirit Lord) and its fellow elementals, and will there be a new Spirit Lord? Why are Shamans, a class that uses the power of elementals, unable to harness Spirit’s power but Monk can? So many questions.
Hope Blizzard has some development on this in the next expac.
I wouldn’t count on it. The 5’th element has been a thing since MoP and Blizzard has never elaborated on it any further. It’s not exclusive to Azeroth either. Draenor has (had) the spirit element too, but it was consumed by a plant or something which resulted in the Everbloom and it’s sapient plant people.
Now, as for why Shamans can’t use the 5’th element. I assume it’s simply because there are no spirit elementals. No “Spirit Lord” or whatever. So they have no one to get it from. Although i believe at some point “spirit elementals” were considered to be the souls various beings (like the player races). 99% sure that’s no longer the case though.
Spirit is different from the other four. It’s more of a unifying force that connects the four main elements together and it’s what gives them life. Elementals exist because Spirit allows them to.
But it’s also a life force that exists in all living things big and small, plants and animals. Monks use it to empower themselves, shaman use it to commune and connect with the elements, druids use it to do all their magic natury stuff. Nature magic and elemental Spirit are the exact same thing. It’s everywhere, just used in different ways.
The titan soul is feeding on it to nurture itself, but it would exist even without her. Azeroth would probably even gain more life magic after she hatched and left. Draenor for example did not have a titan soul and it still had Spirit, way too much actually to the point monstrous sporemounds grew from it. But it’s an eternal thing.
To be clearer. Monks use the chi that exists within ourselves. Every living person has a flame of it inside them, making them alive. Shaman and druids use the outer Spirit permeating the rest of the world do their stuff. Monks have zero connection with the actual elements, we don’t talk to them and or know how to grow flowers.
