Okay – please note that yes I’m serious, no I don’t mean to offend you guys, and I have no idea where to start so I’m gonna just be honest and ask 
Is Elemental Magick like Avatar? With the element “bending” and stuff, or is it more like healing with herbs and stuff?
Both?
Neither?
What have your experiences been?
No, and yes. To get that “Avatar” type of control takes a life time to master but the Elemental Kings can teach it.
The first step, though, is to learn to control the element within yourself.
So what is your goal for learning it? Cause it looks cool? 
If so, that’s pretty useless.
As for how and what’s, your first steps should be towards opening your senses.
This will open up a huge amount of possibilities.
