Better copper armor

Do you feel like the copper armor is a useless part of the progression in survival Minecaft?
That is why I created this mod :)

What does it actually do?

Whenever you wear all four pieces of copper armor, it gives the player a "fortune" status effect

Fortune effect

The fortune effect works very similarly to the fortune 1 enchantment, by giving the player a 33% chance to gain an extra ore when mining veins.
Important notes:

• Only works on the same ores as the vanilla fortune enchantment
• Only triggers when the player holds a pickaxe without the fortune or silk touch enchantment

Why this mod?

Most Minecraft survival worlds start like this:

1. You wander around, looking for loot or interesting spots
2. You go mining, creating you first set of iron armor and tools
3. Then you settle down, building a house, getting better gear and enchanting your items

I felt like the copper armor would fit very nicely in the second step, instead of the iron armor, the player crafts copper armor, trading some protection for better loot while mining. This makes the armor actually useful, since iron is not much harder to get so most people skip copper.
Later, once the player has enchanted gear, the copper armor becomes less useful, since it does not trigger with already fortune-enchanted pickaxes. This places the armor firmly as an early-game mining gear.
