When does Triple XP start?

Erp... Let me clarify a bit.

Immediately after your recruit has created a trial account using your Recruit-a-Friend key, you are able to earn triple experience. There are a few caveats, however.

Make sure that each of the following conditions are true to ensure that you receive the experience bonus:

Q u o t e:

• While in a party together, any experience gains are increased significantly.
  
• If both players are present when the mob is killed both players should receive triple experience.
  
• If the mob is trivial to either character, no experience bonus is earned.
  
  This means that if you have Player A (level 50 veteran character) grouped with Player B (level 30 RaF character) and they kill a mob that is level 32, since the mob is trivial to Player A, no bonus experience is awarded.
  
  
• If one player is 4 or more levels higher than the other but the encounter is not trivial, only the lower player gains the experience bonus.
  
  This means that if you have Player A (level 15 veteran character) grouped with Player B (level 11 RaF character) and they kill a mob that is level 13, only Player B would receive the experience bonus.
  
  
• If both players are present, experience gained from quests that are not trivial (gray difficulty) will be tripled for both characters.
  
• While in a party together, all reputation gains are increased by 10%
  Increased reputation gains apply to mob kills only, not for quest rewards or other reputation granting activities.
  
• All bonus reputation and experience stops at level 60.
