Well I just built one in my house ( I have 42 construction), And I would like to know what it does. I know some people will call my an idiot for building something when I dont know what it does, But it looked cool and had to have a purpose. When I examine it doesn't tell me anything important.

 

Examine elemental balance: It glows a slight green.

 

So... what is it used for?

its a waste of runes thats what lol....its a game where you cast an elemental attack of the corresponding color on it to get it to glow that color

 

 

 

green =earth

 

white = air

 

blue = water

 

red = fire
