Sometimes or I go months without switching,but i'm in a guild event so have to change even moreso when my lamps holder wishes it.
Not sure any Djinn would dress someone like a Ninja maybe an Assassin an Arabian one,but not a Ninja that might be more an Oni your looking for.
Djinn's should have no idea what a ninja even is.
Should be able to find 1001 nights just about anywhere for rather cheap no more then 15dollars for the book.
Well a thief related djinn will probably be Andromalius he is basically the patron saint of thiefs.
Well when I started gaia most items were not on the site it was barebones I started being a Djinn in 07 and believe the wisp item came out in 08 so have been like this for the most part since then progressively getting better and better with items as they come out. Like said I looked at what the other did with her other Djinn equips and Djinn in general she took something from the Keys and made into the equips. I have a good idea for most of the Djinn's how they could end up looking like if all 72 are shown.
