Easter Eggs started appearing in the world zones in patch V3.11 on March 26th, 2016, and again in patch V4.3 on 12 April, 2017.
Spawn rate Edit
There can only be a maximum of one egg per zone. When entering a new zone, there is a 15% chance that an egg will appear on a random cell that's not reserved for a special item.
An Easter Egg on it's own doesn't do anything. It requires the player to click on it to roll one of the random rewards.
When clicked, an Easter Egg will give one of these rewards:
Note: "1x" refers to the amount of a resource player would have received from a loot cell in the world zone, on that particular cell.
|9%||Helium equal to the amount earned in current zone. Below zone 20: 1 Helium (affected by Looting, rounded down, check here for more info)|
|5%||(0.25*Current zone) Nullifium rounded. Gives 1Nu on zone 1|
|2%||A random Heirloom equal to current zone|
|1%||A Void map|
If the player never used the Portal - Helium, Nullifium, Heirlooms and Void Maps won't drop, and Metal will have 46% drop chance.
If the player has used the Portal 1-4 times (ergo doesn't have Void Maps unlocked, but has Helium), Metal will have a 37% chance of dropping instead. Helium will drop, but Nullifium, Heirlooms and Void Maps will not.
If the player has used the Portal 5 times or more, Metal will have 29% chance of dropping, and everything will drop.
These quotes will appear in the message log upon clicking an Easter Egg, and the text varies depending on whether the cell it's located on was already beaten, is being beaten or hasn't been beaten yet.
