Xp eggs in mage guild

[Drake707]

I'm trying to get the purchase to get the Xp eggs to work on all characters in the mage guild, I got Luci's mind up to 7.2K but when I click quest it only offers me to pay 15K gold to help his friend open a shop. If I say yes, it automatically removes the Quest option from the guy. I'm doing it after Xander's arrival in Adretana. Anyone help?
