Mentoring in EverQuest II allows you to temporarily lower your character's adventure level to match that of another player with whom you are grouped or by self-mentoring. All of your stats, equipped items, spells, and combat arts are also "scaled down" to that level. Base combat experience gain is reduced between 5% and 100% depending on the difference between your natural level and the mentored level. You also get a bonus to AA experience earned while mentoring.
