Vein Mining Tips

Keep the maximum vein size sensible on survival worlds so a single swing doesn't clear an entire cave and drain your tool.
Put Vein Mining on a high-durability tool (or one with Unbreaking) if you plan to clear big ore fields.
Add logs to your block groups to turn an enchanted axe into a fast tree-clearing tool.
Use the activation key to switch between whole-vein and single-block mining without changing tools.
It shines when gathering bulk resources for large building and redstone projects.
