25 Runecrafting experience is gained for every dust obtained. Players can only redeem a max of 1000 dust a day. Bonus XP will be used when turning in Rune Dust. Note: Rune dust can only be cashed in once per day. If you log out or went to the lobby after siphoning a Runesphere, you won't be able to get any more Rune dust when you get back. You will get the message: You have already siphoned from a Runesphere today. You will still earn XP, but not Rune dust.
