What Does This Do

Allows Crying Obsidian to be used in the Nether Portal Frame. Use this to make slightly cooler portals or to quickly travel from Ruined Portals!

This datapack changes a single block tag added in Minecraft 26.3, and therefore should not cause any unexpected behaviour. It only adds Crying Obsidian as a possible block to make the portal. Regular Obsidian can still be used, though now you can mix-and-match!

There is not much more to say about it!
