ThreeByThree is a lightweight Paper plugin that adds an enchantable 3×3 mining effect designed as a late-game upgrade for pickaxes. It’s built to feel like a natural extension of vanilla gameplay while keeping performance and balance intact.

Mining Behavior

• When active, breaking a block mines a 3×3 area aligned to the face being mined
• Only blocks of the same type are affected
• Protected blocks are automatically ignored
• Mining is handled safely to prevent duplication, glitches, or exploits

Enchant Behavior

• The ThreeByThree enchant can exist on Diamond or Netherite pickaxes

The 3×3 mining effect only activates when all conditions are met:

• The pickaxe is Netherite
• The pickaxe has Efficiency V

Player Feedback

• If a player attempts to use the enchant without meeting the requirements, they receive one warning message
• Messages do not spam while holding the mouse button
• Switching to another item and back resets the warning message

Admin Commands
