If you want the 3x XP while boosting, you need a minimum of 3 accounts

Account A: Holds your 80 that you'll boost with
Account B: Holds boosted toon #1
Account C: Recruited from Account B, holds boosted toon #2

All three need to be together for the triple XP to work...


If you have only an 80 and a low level toon, the low level toon will not gain triple XP because your 80 is not within 5 levels of them.
