Buying Exp eggs

[littlebro]

One thing I know that is not in the walkthroughs is where/when/how to buy Exp eggs from Cyan in the Mage Guild. I have never been able to get this. Does anyone have the details so that I can edit it in?

I am assuming from the posts that this happens after you've been able to get the Brain Dazzler, therefore it can only be after you've reached level 5. However, there must be some combination of levels, quests, main story developments which triggers this. I kept going back, but never managed it and it would be a shame if it is not included. Any help would be appreciated.

Thanks
