Scorch Release is the result of combining Fire and Wind release. It is a slightly different reddish orange hue than normal fire, but other looks similar to fire. It is unique in that it has hotter temperatures and is capable of evaporating water for its targets. In the RP this typically can have a variety of effects, but in canon jutsu this typically means the target loses a time frame from exhaustion.
Scorch is weak to Earth, Lightning and Black Lightning, and Dark Release's absorption ability. It has an advantage over wind for obvious reasons, wood and plant elements because it would evaporate the water from it, and water based elements like boil, water, storm, etc because it evaporates it.
