What's the difference between the earth storm diamond in World of Warcraft and the powerful earth storm diamond?

These two attributes are different. Ground riot diamonds need prestige to buy, and the methods are as follows:

1. First of all, players need to come to the senario Shelter in Outland Zan Gamache.

2. Find Neardre Xunspier near coordinates (79, 64).

3. Click on the dialogue to buy the formula: synthesizing Earth storm diamonds requires the prestige and respect of the senario expedition.

4. After learning the formula and preparing the materials, you can transform yourself: Earth Storm Diamond.
