ok, due to new questions:

-there is no magic in this rp, its purely based on elemental powers and modern time tech
-everyone is free to create their own style for an element as long as it makes sense (basically, you cant use fire as a giant boulder for blunt damage as its Plasma, having no mass to deal blunt or cutting damage or grab for that matter, you can walk though fire if your not effected by the flames, a giant boulder you cant go though)
-about Pure you can also say its both light and dark fused into a new state, its not the real physics behind it but it may be an small explanation for those who dont know my other explanation about it

just wanted to report, the solid elements have an little upside to them that the others lack
if you lose a human limb, replace it with an element made limb XD (like, if my crystal char loses his arm, he can make a new one with his element XD)
most elementals can restore energy or health and such by absorbing their own element when in element body, but more on that will come when I get to the point of explaining element body info (which depends on if Constantine agree's with my idea about continuing weaknesses chart later)
