Question about Item

[HoLy]

What exactly do Worldstone Fragments do? And how many are in each set and where can you find them?
I have the Red one. Thanks.

So there are 5 worldstone fragments. They are:
Green (Drops from Andariel)
Yellow (Drops from Duriel)
Blue (Drops from Mephisto)
Red (Drops from Diablo)
Gold (Drops from Baal)

To learn what to do with a full set, read this

Its in Wiki=>Content Guides and Character Guides=>Guide to the Worldstone Event (endgame content).
