Quests legends

[Xeinlad]

I have a question that I searched and hesn't been answered anywhere. What does the legends of the quests mean? I don't mean if they are main quest or side quest. I mean the legends that are1,2,3 stras, when it shows like a note, when it says daily (that I can guess). Where I can obtain that information?

That's like a difficulty rating.
