Skill Slot System

In an RPG that uses Jobs, there can be many different ways to do it. There's the many variations on the classic Job System, there's the Character Class System, the Class and Level System... but the most popular way of doing it is probably the Skill Slot System.

Simply put, a character has a choice of several jobs, and at a certain level the job learns a new command/innate ability. When the character reaches said level, they'll gain the skill, and can assign to one of X (usually four) slots for a skill, and they can then use it.

Compare Job System, Class and Level System, and Character Class System.
