Minecraft wiki entry for Hardcore_mode, associated text: It is hard to have too much gold because it is good for making golden apples, and Netherite ingots. 8 ingots are required for a normal golden apple, and since the 1.9 update, enchanted golden apples aren't craftable. Be sure to grab some redstone for brewing potions. Lapis lazuli is required to make enchantments, so don't forget to mine it if you find some.
