As is trite knowledge, Spells are classified into categories; Basic, Intermediate, Advanced, Peak, and Transcendent.
Each of these categories are divided into Tiers— from the Lower up to the Highest Tier. There exists Middle Tier and High Tier levels between the two.
However, for every general rule, there is always an exception.
The same is true for Spells, and Magic as a whole.
There are certain Spells that do not belong within the cadres of ranking. They can be used depending on how much Mana a user has, and their proficiency with it. And as a result, these Spells are considered very versatile. It is said that many highly regarded Spells are simply offshoots of the exceptions.
The Spell [Shock] is a good example. It's powerful enough to stun someone at the hands of an amateur, but a true master could use it to completely fry multiple foes at once.
But, [Shock] has a weakness. It's range.
