Steel should be added, do you agree? I believe u need to but 4 iron ingots in a square to create 4 Steel Blocks, Steel would also require an Iron grade or higher Pickax to break. Steel would be a charcoal color with a sort of Lapis block like Texture. You may also use Steel for tools as well, They are only slightly better than Gold Tools though. Do you Agree with Addition? It will also lead to Stairs and slabs as well.
