how do you get master of oasis badge i have don all the quest in krokatopia even the deck one
Here are a few side quests from Krokotopia that I missed in the beginning:
1. Mshai Djeserit in The Ahnic Family Tomb, and 2. Buikhu Djeserit in The Djeserit Tomb, and 3. Mah'rek at the Tomb of the Beguiler. (You don't have to actually do the whole dungeon. Just go in and talk to the first person there, then leave.)
And I found that if I did the last quest that Sgt. Major Talbot gave me, to go to Marleybone and talk to Sgt. Finchley (not sure of his name), that's when the badge appeared.
