As it was posted before, the people around the tents provide the quests you need for the mystery armor and helmet. The weapon quest is found inside malik museum from ramla holding the royal shadow staff. You have to pay 5 platinum in order to get the quest (or is it the recipe). Once u purchase it u must find this super hard item from ANY d'jinn enemy around alien oasis. Took me a while but you could do some cyber questing on the way!
