which class?

Frater unless the European RAF is different, I'm pretty confident it's 2 levels per free level for us.

What in-game benefits do we get while the accounts we play are linked?
1. Characters on both accounts can summon each other once per hour.
2. While adventuring with your linked friend/family member, you will each gain triple experience.
3. For every two levels the new player earns, the new player can grant one free level-up to a lower-level character played by the veteran player.

Do I always gain triple experience while I am linked to my recruit?
No, only when you are partied with a character on the linked account and both players are present when slaying the monster or completing the quest. Also, if the two characters are not the same level (4 or more levels difference), no bonus experience is granted to either character.

So appears I was wrong about the lower level thing to an extent, but I was right about the 2 levels per 1 Granted.
