This thread got confusing really fast, its like everything I knew just got changed e_O.

From my understandings, this is how RAF works with multiple accounts.

Lets say you link your 4 accounts as such, A -> B -> C -> D.

Now, lets say you use a 70 on A to boost toons on your other accounts. It seems this is where everybody is contradicting each other. From my understandings ALL of your slaves ( toons on accounts B, C, and D) WILL get the RAF bonus when grouped with your 70. This may be a little confusing so try to bare with me.

This is what should happen with the RAF links. Account A is linked to account B. A is the level 70 used for boosting, B has a fresh level 1. B normally would NOT get RAF xp because the character on account A is not the same level.

BUT, because account B is linked to C, it will still gain RAF xp (assuming both characters on accounts B and C are of equal level and below 60). You character on account D will also get RAF xp because it is linked to C (assuming both characters are of equal level and below 60, as stated before).

Hope I haven't lost you. Basically, do as others have stated. Daisy-chain ALL your accounts together (A -> B -> C -> D). With this configuration your main account, A, will receive all the benefits of RAF (1 month free, zhevra mount, gifted levels, ect...) and you will still be able to boost your other accounts.

Oh, here is a link to a thread with some very helpful info on some other aspects of RAF.

Hope this helps a little
