Bonus Experience

BEXP or Bonus Experience, is something introduced in Fire Emblem: Path of Radiance, and it followed on in Fire Emblem: Radiant Dawn. Bonus experience allows you to give experience to units you feel should have it. For example, say you have a level 18 Nephenee. You could BEXP her to level 21 where she would premote. Thus becoming stronger and better.

Most people wait till their unit has maxed certain places they normally would max out. For example, Mia. Mia normally maxes out Speed, Skill, and Strength. If you BEXP'd her she would grow in other stats that she normally wouldn't grow in.

When you give a unit BEXP they will only grow in the three stats with the highest growths.
