World of Warcraft seeks the formula source of blue stone and purple stone after World of Warcraft 300+ jewelry processing (including the place where I can buy paper after my reputation reaches a certain level). Jewelry mainly comes from the Star Consortium. People who want to cut the blue need respect (Astral Consortium, the lower left camp of Nalan Harlan).

There are patterns in other places, but I will give you a blue one after reverence.

After 300, I still rely on green. Salma, senario and NPC can learn 350.

After 350, it is mainly made of purple and blue materials.

If you are 70 years old, quickly smash Sun's reputation, and then give blue patterns from friendly to purple.
