Summoning Eye

The Summoning Eye is an item that is used for summoning the Ender Dragon in The End. It is dropped by Special Zealots holding End Portal Frames that rarely spawn after killing a Zealot. Killing Zealots for Summoning Eyes is also a good money-making strategy as one Summoning Eye sells for.

Obtaining
When a player kills a Zealot, there is a small chance that another Zealot will spawn holding an end portal frame nearby, dropping a summoning eye if killed. They are called "Special Zealots" by the game. The chances of a special Zealot to spawn is 1/420, and if the player killed 420 Zealots and did not spawn a Special Zealot, the chances are doubled. More about Special Zealots can be found on Zealot.

Players will receive an alert in chat reading " " and the wither spawn sound will play. When a Special Zealot is killed, it will give you the rare drop message, even if you were not the one who spawned the Zealot. Using a Enderman Pet (LVL 100) will increase the chances to 1/315 chance of a special zealot to spawn.

Usage
Summoning Eyes are used for summoning one of seven types of Ender Dragons. When a player right-clicks an empty portal frame with a Summoning Eye, it will be placed and turn into a Sleeping Eye, allowing for the player to retrieve the eye if needed. If the Sleeping Eye remains in its form after 8 eyes have been placed (one in each portal frame), it will turn into a Remnant of the Eye.

Tips

 * It is recommended to use Young Dragon Armor while farming Summoning Eyes to gain as much speed as possible.
 * If the player's Farming level is at least 21, Farmer Boots are great for increasing speed further than Young Dragon Armor can on its own.
 * Note that while Farmer Boots may make the player faster, they will not increase the speed cap.
 * It is recommended not to use Summoning Eyes to summon an Ender Dragon if you cannot deal enough damage to reach the top 3, as it is mathematically quite unlikely to break even or make a profit. Rather than using the summoning eye, it's best to sell it for a guaranteed per eye. If you do use them to spawn dragons, you should do a large number of dragons at once since most of the potential profit comes from the chance to get a Superior Dragon, Aspect of the Dragons, or Ender Dragon Pet.
 * Keep in mind you have 5 seconds of pickup priority before someone else can take your Special Zealot's Eye.

Trivia

 * Not being able to 1-shot a Zealot will increase the chance of a Special Zealot to spawn by 10% (1.1/420)
 * The chance of a Special Zealot dropping a Summoning Eye is 100%.
 * Since the chance is 1/420 (0.2380952380952381%) by default, one 10% increment will be 11/4200(0.2619047%), and so on.
