Wizard Class is a subset of Warrior Class. They are roleplay characters who utilize un-specific magicalabilities. This category contains wizards, witches, and other magic users. It is for roleplay characters that are defined by their ability to cast magical spells, not for characters who used magic once but do not usually do so. It is also not for creatures that are inherently magical but do not actually cast spells.
It is possible to be in two classes. For instance, if a roleplayer wants to be in Warrior Class but isn't interested in Dragon Ball-style roleplaying, they can take on this sub-class and train to become an Adventure Time-style wizard.
To become a Wizard, a roleplay character must train at WartHog's School for wizards.
