Golden carrots add 30 luck to lucky blocks. They cost 8 gold nuggets to craft, which is less than a single golden ingot. Yet somehow, golden carrots are 5x more effective at adding luck than a single golden ingot.

Also, golden apples cost 8 gold ingots to craft. 8 gold ingots add 48 luck to lucky blocks, but golden apples only add 40.

Can the luck values be changed?
