The Ender Lucky Block is special because it doesn't give the usual Minecraft items when opened. Instead, it surprises you with more than 40 custom items that are all related to the End. It adds an extra layer of fun by mixing these special items with the regular stuff you'd find in the game.
All items have a random chance of dropping, but vanilla items have a higher chance of dropping than custom items. There is a 35% chance to drop custom items and a 65% chance to drop a vanilla items.
