EchoDupe

Echo Shards can now dupe ORES, namely:

• Coal Ore
• Deepslate Coal Ore
• Iron Ore
• Deepslate Iron Ore
• Copper Ore
• Deepslate Copper Ore
• Gold Ore
• Deepslate Gold Ore
• Redstone Ore
• Deepslate Redstone Ore
• Emerald Ore
• Deepslate Emerald Ore
• Lapis Ore
• Deepslate Lapis Ore
• Diamond Ore
• Deepslate Diamond Ore
• Nether Gold Ore
• Nether Quartz Ore
• Ancient Debris

This is done by placing one Echo Shard and one of the aforementioned ores in the crafting grid. The output is two of the respective ore, effectively doubling the ore at the cost of one Echo Shard.

WHY ORES?

I chose ore duping over item duping because doubling the ores first before Fortune yields more rewards per Echo Shard. Also, this way ore duping is locked behind Silk Touch making it less viable early on, and, in my opinion, more rewarding late-game.

WHY I MADE THIS

This random Reddit post I came across: https://www.reddit.com/r/PhoenixSC/comments/1vl52pm/what_if_echo_shards_could_be_used_to_craft/

It also served as practice in creating my first datapack. If you do not like something about this, feel free to modify it; I can assure you it is a fun experience to make your own data pack.

As a bonus, the Notch Apple and a mystery item can also be duped in the same way~
