Hi, I'm trying to get the Dao of Pow. In order to get that I need a dark shard, which is gotten from dark/shadow mummies. However, they spawn in corrupted deserts, which is the problem. I have tried to make a corrupted desert for a few days now, but with no avail. I even tried resetting terraria, and it didn't work. Any pointers? Am I doing something wrong? I have an iPad Air with iOS 8.4 and terraria version 1.2.8631.
