Hello all, just creating this thread to keep track of the Druid King fragments on the PTS.

There are 5 fragments:
Delver's Druid Deck Fragment -> Drops from delve bosses in Galen
Dreamer's Druid Deck Fragment -> Drops from the last Galen main quest "The Dream of Kasoryn"
Geomancer's Druid Deck Fragment -> Drops from Volcanic Vents in Galen
Slayer's Druid Deck Fragment -> Drops from Group Bosses in Galen
Soothing Druid Deck Fragment -> Drops from "the best of friends" achievement

If anyone finds missing fragments, let me know and I'll update this post. All info has been found.

Cheers.
