I say Thermight, Aluminum Powder, and Rust shouuld be added to the huge amount of elements we already have. Thermight's explosive property is a Plasma hot with a magma like substance and should ignite under pressure and at very very low temperatures. Aluminum Powder being a sort of lower temperature than regular flame being used usually to start camp fires would be as if a short spark. And Rust being a compound mixed with Aluminum making Thermight should just be Broken Metal(Should be renamed Rust in my opinion) And should turn into Thermight when mixed together.
Thermight being [THRM] Aluminum Powder [ALPD] and Rust [RUST] Thermight's color is usually a crimson/maroonish red, Aluminum Powder is a silverish/grey, and Rust is usually a brick red
lol I am sorry I never looked at the last few updates and rust is just like Broken Metal just diferent and ALuminum Powder mixed with Rust make Thermight
