Thunderstorm Magic

Thunderstorm Magic (雷雨魔法 Raiu Mahō) is a Caster Magic and a specialized form of Lightning Magic.

Description
A Magic that allows the user to manipulate the weather by generating localized thunderstorms or control pre-existing ones.

The lightning accumulated in the clouds can be aimed directly at the target from above and, in the case of natural lightning, its speed will make the attack nearly impossible to dodge.

The power of the generated storm depends on the number of Magic Seals the user creates, which appear progressively larger above the user.

The size of the storm will vary from a little cloud, produced at level 1 and capable of discharging a few bolts of lightning, to a massive storm, produced at level 5 and capable of destroying the area below by raining thunderbolts.

A particularly skilled user will be to reach level 6, where they'll be able to drain their magic from the level 5 storm above without making it disappear, effectively producing a thundercloud capable of discharging natural lightning. This procedure however is very delicate and requires time to be completed, consuming many times more magic than the level 5 spell.

A true master of this magic can take it a step further and deploy a level 7 spell, which will amplify the level 6 storm by a massive amount and summon a supercell thunderstorm dozens of kilometers wide, capable of persisting for several hours.

Spells
Kirin (麒麟): After summoning a level 5 storm, the user can concentrate its entire power into a single strike, shaping the generated lightning into a dragon-like shape and guiding it on the target. The user can also perform this spell with a level 6 storm, which uses the natural lightning capable of reaching the ground in 1/1000th of a second. As there is little ethernano in the attack, most of the energy will ignore the passive resistance mages possess against spells.

Both variant require little magic to be deployed but its usage seems to disperse the thunder clouds. As such, this technique can only be used once in a fight. Tenpenchii (天変地異 Cataclysm): After summoning a level 7 storm, the user is able to release its entire power in the span of minutes, the simultaneously creating a variety of natural disasters that devastate the surrounding area, with themselves acting as their epicentre.

The phenomena involved in this technique include: floods, thunderstorms, and tornadoes. These concurrent events result in a blast akin to a nuclear explosion, releasing a vast mushroom cloud upon the conclusion of the spell.

Most of the magic required to deploy this spell lies in its preparation and as such it requires very little to be used, however the supercell disperses after each usage. Demon Dragon Storm (嵐鬼龍 Rankiryū): By deploying the Magic Seals around themselves instead of above, the user generates a thick ring of thunderclouds and electricity around their body, creating an offensive and defensive ward. These clouds can fire powerful blasts of lightning and act as an electrified perimeter, effectively preventing enemies from getting close.
