Experience points are used in all three games in the Mother series. The purpose that experience points serve is for leveling up. For example, when Ness gains enough Exp. Points, he can level up and learn things like PSI Rockin or Lifeup. Some PSI are not recognized by leveling up. Such as PSI Starstorm Alpha and Omega are learned through the ways of the Star Master or Ionia.
Gaining experience points
Experience points are usually gained by defeating enemies: the tougher the enemy, the more experience you get. There are a couple of exceptions to this, however:
- In EarthBound when Ness finishes in Magicant: he gains 200,000 experience points on the spot.
- In Mother 3, Salsa gains 50 experience points when he gives dung to a dung beetle in the desert for the first time, and 5 each time thereafter.
