Fastest way of earning money is doing the Egg, Food, and sometimes toy Quests on Novice level. Most of my draqua eggs end up going to the Egg Quest.
I'm trying to save some of my Uilus eggs for trading later. I'd love a Black Iluvu and Black Easero. But I'll probably hatch all natties. I collected 17 Uilus eggs and have 10 left. All have been nattie so far. I may save the last for trading.
If you let me name colored draqua, I'd buy them from you. I need to build up my tu though.
