From a business perspective, I would not come to atlantic to sell powerscrolls. Everyone is doing that, and as a result, there is no market cause you have to go REAL cheap to sell your scrolls now. My bud just bought a 120 resisting spells for 4mill. If too many people flood one particular shard with too many of the same item, you won't sell it unless you undercut yourself by a ton. There are atleast 20 powerscroll vendors I have seen that haven't sold squat do to the fact that they all stay at the higher set price.

I'd recommend trying another shard with a slightly less population but less competition as well.
