I'm really new to this.. But I really can't figure out how to get it to work. I want to make an Ore thats similiar to Diamond, I have got the spawn rarity to work and I'm happy with it but I can't get the Harvest levels right. I want the Ore to only drop its drops when it's mined by Iron or Higher pickaxes, yet no matter what level I set it at wood can still mine it and get the drops.
Can someone tell me what I'm doing wrong?
