Thunder is a very hot liquid/gas-like substance that passes a SPRK to any conductive materials. It will create a strong pressure shock wave (256 pressure) as well as conducting its temp when in contact with non-metals (or metals that are unable to conduct electricity because a spark has just passed by). THDR's movements are not affected by pressure.

THDR is commonly used to create large amounts of pressure (and heat), most commonly to start fusion reactions (by mixing it with HYGN) However, since it has very low heat conductivity, it is not a very efficient way to produce heat.

Similar to Fireworks (FWRK and FIRW), there are 2 different "Lightning" elements. (THDR and LIGH) However, the 2 lightning elements are much more different, both in their names and their properties.

Worth noting about thunder, it is one of the few elements that can stack naturally without use of walls or other external tools.
