Diamond to Obsidian Shulker Box Upgrade

The Diamond to Obsidian Shulker Box Upgrade is an item added by Iron Chests. When right-clicked on a Diamond Shulker Box, it converts it to an Obsidian Shulker Box without changing the contents or the color. This item was removed from this mod and put in Iron Shulker Boxes for Minecraft 1.13 and later.
