Formula

Formula (式, Shiki lit. Style) is a Caster Magic, one that is considered very "basic" in nature, and involves the usage of Magic seal in order to allow for enhancements to both physical and magical attacks.

Description
Formula requires great control over one's Magic, and Magic energy, allowing them to even manipulate magic seals, without casting a spell using them. By using magic seals, a Mage can "formulate" it to have enhancement effects to their attacks, be it physical or magical. For example, one can create a Formula magic seal that increases the strength of a punch, or a weapon, making it far stronger than prior. It can also increase speed, and durability of physical attacks, thus, it possesses great use, even for martial artists.

As for spells, Formula is capable of not only increasing the strength, and speed of a spell, but also increase its size, adding more destructive power to it. However, due to it requiring Formula to be casted first, it means an extra amount of magic energy must be poured in order to cast a spell immediately after.

The seals created via Formula have two sides, the first is the one always facing the user, which, once an attack passes through it, it will recieve the enhancement. However, the opposite side of the seal lessens the power of an attack, by the same amount it is meant to be increased. This means that Formula also possesses minor defensive capabilities.

It should be noted that Formula seals can also grant one enhancement per seal, thus requiring multiple seals to be casted, to add even more strength, and additional, different enhancements. The amount of enhancement added in a Formula seal is typically counted in percentages, with some reaching up to 100%, or even up to 120% by those skillful enough to push to that limit.
