-Magic Storage Void Bag is a pretty cool mod, it does...this. Modify this file with a description of your mod.
+Adds an upgraded void bag that combines functionality of the Void Bag and Portable Remote Storage Access, by putting items into a magic storage system when your inventory is full (and allowing remote access as usual).
+This item is crafted by combining a Void Bag with a Portable Remote Storage Access, and a Radiant Jewel. To link it with your storage system, right click the Storage Heart with the bag equipped.
