Sukaireiji

Sukaireiji or "Sky Rage" as it translates to is a storm-based developing magic.

Novice
The user has first learned it and they have a high chance of striking themselves with lightning when using, which is why an item with a resist or immunity is recommended when learning the magic. NEVER where metal armor at this stage especially when practicing as the metal armor will draw the lightning in and thus striking you.

Apprentice
Apprentice users have a better time controlling it and can actually focus it onto a metal object giving it electrical properties temporarily and using it for combat. If you are born with Sukareiji the you are most likely already at this stage by the time your a child and can control it a bit better. Without a storm at this stage the magic is useless since it doesn't generate the magic on its own and simply draws it out of the sky.

Adept
Adept users can create small storms and change how powerful natural storms are thus allowing them to use their magic whenever as long as they are outside.

They can also accurately control lightning, if lightning were to try and strike them they could redirect it away from them and their companions.

Master
???

Advantages
Wet Targets are easy to hit and take a lot of damage.

Metal Targets are easy to hit

Striking an animal has a chance to cook it,

Weaknesses
Rocks are immune to this

If the user is inside they cannot use their magic without striking the building they are in.

Other times it just turns to ash.

Learning
You'll need a basic understanding of water/wind magic (having both makes it easier when it comes to Adept) you can probably find a book or even a user that will teach you for a hefty price as it takes time to master and in the beginning is very dangerous.
