detector enchantment

this would be a treasure enchantment that works on any piece of armor. upon equipped it would weaken the armor

1. full diamond armor would now equal full iron armor
2. full iron armor would now equal  full chainmail armor
3. full chainmail armor would now equal full leather armor
4. full leather armor now equals the same armor as 1 leather chest plate no other armor

but in exchange it will have a arrow appear in the corner of the screan that will point to the nearest iron ore with a 20% chance to point towards a diamond ore and monsters can now spawn 6 blocks closer to the player with a 5% chance to spawn 6 blocks away the player in question in multiplayer this downside to over written when the player is next to another player(cause the other player isn't wearing the same armor)  now this might be op but I think the nerf to armor is so massive and makes mining so much more dangerous that it balances out
