Thermal Magic

Thermal Magic (温熱性魔法, On'netsu-sei Mahō) is a magic that allows its user to manipulate the temperature of any matter they subject their magic to. It is a Caster-type magic and is the basis for other thermal-dependent magics, like Ice and Fire.

Description
Thermal Magic allows the user to increase or decrease the temperature of matter by placing it under the control of their magic. This is done by altering the rate at which the molecules within the matter move. Speeding up the vibrations between the molcules heats the object up and slowing down the vibrations cools it down.

Thermal Magic is an incredibly useful magic, though its lack of physical substance makes it almost impossible to utilize defensively, keeping it as a supplementary- or offensive-type magic. Despite this minor setback, the magic's capabilities do not deter others from learning it, the potential for the magic far outweighing the loss for most.

By generating a great deal of molecular movement, the user can superheat any matter they choose to a whopping 2950°F (1621°C), which can cause most metals and liquids to melt and evaporate, respectively. Most attacks that are initiated while utilizing this portion of the magic are done through this simple overheating tactic, though the effects are quite devastating. By superheating the air around a living creature or the matter within their body, the user can cause severe burns and blistering to occur as well as potentially kill them from hyperthermia. By heating up an armament or body part, the user can inflict attacks with incredible heat, allowing them to burn their targets with physical strikes. By concentrating raw heat energy in an incredibly centralized area, the user may create beams, arcs, blades, and waves of heat to damage their opponents from a distance, though a large deal of concentration is needed to prevent the temperature from balancing itself out within the air. Additionally, the user may create a barrier of sorts though it's generally weaker than any other elemental barrier.

Adversely, by reducing the molecular movement of matter, the user can cool and even freeze it, capable of achieving -418°F (-250°C), allowing the user to freeze or condensate liquids or gases respectively. Attacking with this form of Thermal Magic is generally more difficult and slower, though not impossible. By dropping the temperature of the air around their target or their target's body, the user can cause their target to experience hypothermia, reducing their ability to move efficiently as their muscles begin to lock up or even freeze, effectively rendering them immobile if they so choose. This can slowly kill their target's cells and eventually kill their target as their organs are shut down one by one. By surrounding a weapon or body part in the cold energy, they can freeze the liquids on and within their opponent's body upon contact, making it difficult to move. They can create beams, arcs, blades, and waves of cold energy, allowing them to damage their opponent from a distance, though the concentration needed to prevent the temperate from equalizing prevents the user from doing much else. They can use this property to severely reduce the kinetic energy in a spell coming towards them, allowing them to slow it down or even dissipate it, making it a much better defensive tool than the other side.
