To find this new ore you need to travel to The End, Netherite tools (and armor) are upgraded via a smithing table. You upgrade your Netherite with a DinOre Block and pretty much all the tools can 1 shot anything with high durability, this addon is made for Minecraft Bedrock Edition, ports to Java are welcome :)

The original idea for this addon was from my cousin (who's name I will not disclose)
