Harvest Levels and Tool Tiers
The harvestLevel property corresponds to the material tier of the tool. In Minecraft, the standard tiers are:
- Level 0: Wood / Gold tools
- Level 1: Stone tools
- Level 2: Iron tools
- Level 3: Diamond tools
- Level 4+: Modded materials (e.g., Obsidian tools, Cobalt, Manyullyn)
If you set a block to harvestLevel: 3 and harvestTool: "pickaxe", a player must use at least a Diamond Pickaxe to receive drops from that block.
