I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Description

Development on this instance of the mod has ended, for a 1.20 version and other future developments, check out The Last Sword You Never Forgot

This mod adds a sword that will kill nearly anything in one hit. The sword is a universal harvester for all destructible blocks.

To start off you need to kill the ender dragon. It will drop some dragon crystals.

Next, you need to craft those into dragon gems, that's a 3x3 grid filled with crystals.

Then you can use two of those for the blade and the ender dragon egg for a handle to craft the Dragon Sword Tier 0. To upgrade any tier just surround it with dragon gems in the crafting table.

Oh, and there's also an armor set with a full set effect buff.
