I got two mummy shirts and a single pair of mummy pants before I got a light shard. After a some time, I finally got the two light shards I need. Now, all I gotta do is go to the underground Hallow and get Souls of Light. If you're wondering what I'm doing, I'm trying to get the Sky Fracture.
Also, I've been thinking of ways to improve the Frostspark Boots, so I might make that into a suggestion.
