Survival Expansion III requires more steps before entering the end. You must craft an Ender Key to enter the end. The Ender Key requires that you beat 2 bosses: The Wither for its Nether Star and Ascalaphus for his Ichor Tear. Ascalaphus can be summoned at a Summoning Station with Glowstone as the ignition. Combine these items in a Haven Altar with an amethyst shard to get an Ichor Emblem, the first crafting ingredient to the Ender Key. The second ingredient, the Adamant Ingot, is found in the Magician's Dungeon. The final ingredient, the Neptunium Crystal, requires that you enter both of the new dimesions. You must find the Ancient Gemstone in a Haven Igloo within the Havenlands dimension and the Ancient Jewel in a Dread Castle in the Dreadlands dimension. Combine the Ancient Jewel, Ancient Gemstone, and a diamond in a Haven Altar to craft the Neptunium Crystal. Now combine the Ichor Emblem, Neptunium Crystal, and Adamant Ingot in a Haven Altar to craft the Ender Key. Now you may enter the end and kill the dragon. (This would be the end of Survival Expansion I)
