Combustion

Combustion (燃焼, Nenshō) is a powerful version of Fire Magic utilized by Nathan Vulcana.

Description
With this magic, Nathan concentrates his energy through any part of his body; usually his hands to project a ray of heat which would detonate with great force, producing situated explosions with a great deal of precision. This technique is extremely effective and very destructive, capable of use at close and long-range; it can completely disintegrate hill-sized boulders and instantaneously evaporate large bodies of water with ease.[22] He can also employ it to burn things without setting an explosion, similar to a lens focusing sunlight. This is probably due to the energy being entirely focused into creating the explosion, without wasting energy maintaining a long-range jet of flame. However, the technique has the potential to be just as hazardous to the user as it can be to their surroundings.
