i have 1 quest and it will give me 20k xp if i finish it but i dont know what to do, there is nothing on map, and i dont have any quest item in my inventory.
it says something pilaf fountain, pilaf memorial, something like that, and there is 0/5 twice.
i ll take screen shot if it will help

I don't know the quests so correct me if I'm wrong but that sounds like it wants you to kill or collect something in Pilaf.

Ud3

Yeah, Pilaf is UD3.

If the quest looks like this then you have to run Pilaf and kill the bugs:
