Experience Points, usually abbreviated as EXP, are a recurring feature of the Dragon Quest series. Experience Points have been present in every main series game and nearly all spinoff games.
Experience Points are gained at the end of a random encounter or other battle as a reward. More powerful monsters reward greater amounts of Experience Points.
When a character accrues a specific, predetermined number of Experience Points, they will "level up" (that is, gain a level of experience) and receive statistical increases particular to their overall character type. In most games, this is characteristic of the party member, though in Dragon Quest III and Dragon Quest IX stat growth is dependent on the character's class.
Alternatively, a character wearing the elevating shoes gain an experience point for each step made out of battle. This accessory can be found in Dragon Quest III, Dragon Quest IV, Dragon Quest VII, Dragon Quest VIII and Dragon Quest IX.
