In NEI under the latest Ultimate pack version, there is a "Soul Crystal," item ID 1478. Using the keyboard shortcuts while mousing over the slowly spinning crystal in NEI, it shows neither Uses nor Recipes for it.
Anyone know what it is? It's not a Soul Shard, or the crystals or crystal clusters you can dig up that are Thaumcraft's, so I'm just curious.
Reason I was looking up "soul" was if there was anything that stored experience levels in FTB like there was in Technic pack. I have 76 levels from all the work I've been doing on Soul Shards and related spawners, and I really don't need to enchant anything right now. First thing you know I'll get blown up by a creeper or fall in a Quarry and it will be gone.
(EDIT: the item is in neither the old nor new wikis, at least under the apparent name "Soul Crystal.")
