Easter Egg in Easter Land dimension

The version you should use now is 1.1.0. This mod is primarily designed to work in the spring addon modpack used for my communitiy server: here. If you want to thanks me do not hesitate to write me in the comments or maybe support me on youtube @CrafTot7.
Feel free to use this mod in your modpack, but I would highly recommend to use the previously mentioned modpack for a better experience.

Some settings that better fit the mod:
GUI scale: 3 (better for ranking system)
Optifine with Sildurs shaders.

The discord server (french-speaking mainly): here

Easter Land (new dimension):
Easter Forest: a biome featuring all other biomes together plus easter eggs, giants chocolate bunny and more.

Ores:
Easterium: a rare ore only generating in the end and in the Easter Land.
Springerium: same as easterium. Its ingot can be used to craft the Easter Land portal igniter.
Eagerium: a combination of the two above. The most powerful ore in the mod for now.

Blocks:
All the types of wood mentioned above have their usual decorative blocks like stairs, slab, etc...
Easterium blocks: used to make the portal to Easter Land (like a nether portal).
Springerium blocks: only decorative for now.

Plants:
This mod is featuring a large amount of new flowers and plants. Most of them are only used to produce essences for tools upgrade (see below), but some like verticis, spinis or others, may start to grow on their own.

Tools:
Each of the wood type mentioned above can be used to create, from a netherite tool, an enhanced version with particular effect depending on the wood you use. I won't spoil the effects here. Grab 2 netherite ingots and try all the stick types.

Upgrade the tools:
Each of the tools added by this mod will have 6 possible level of upgrade, from the vanilla one to the level 5 upgrade. To upgrade your tools, you need to combine them with the correct essence type. The essences can be obtained via flower juices. Putting a red flower in the crafting table will give you red juice for example. You will then need to combine these juices to obtain highly concentrated essence. Do not panic, Just enough item will give you all the recipes if you use the "official" modpack for this mod. Notice that the ebony tools need all the kind of essences to be upgraded but all the others requires the essence corresponding the tool's color. Example: rosacea tools are upgraded using pink essences that comes from pink flower types.

Additional weapons:

Upgradable easterium spears: can be crafted from any wood from the mod.

Upgradable springer halberd: can be crafted from any wood from the mod.

Both of those kind of weapons are upgradable. Will you find out how?

Easter eggs hunt ranking system:
When joining the world, you will start with an pink egg on the top left of your screen. This represents the rank you achieved for easter eggs hunting. You can look at the rank's list when pausing the game (on the right from bottom to top). To rank up, you need to break easter eggs inside the Easter Land dimension. Remember that this dimension is only accessible after accessing the end if you do not cheat, so the dimension is designed to be accessed by prepared players. You can check how many XP points you need in the top left corner of the screen when you pause the game. Notice that dying will make you loose some points. The values of the different type of easter eggs are as follows:

Colored: 1XP
Bronze: 2XP
Silver: 3XP
Gold: 4XP

Your rank will be visible by all player in a greeting message when you join the world. Also, your rank will be appended at the end of any message you send.

Easter eggs are not regenerating in the Easter Land (at least not for now).

Pollen waves:
Randomly in the world, pollen waves will hit the world. During these waves, the air will become yellow-tinted and pollen will be placed on grass blocks. You can right-click on them to obtain pollen and yellow essence. A count-down will keep track of how long the pollen wave will last. Easterium and Eagerium helmets will protect you from the yellow-tinted air.

Machines:
Essence generators: each type of essence has one corresponding generator. It needs pollen and the level of essence you want to produce in order to work. Note that if you break the generator, it will lost its pollen charge.

Life catalyst: the ultimate machines in this mode. It will repopulate an entire area with flowers, giving you tones of essence of 5 types (some are kept more rare for unknown reasons)

Entities:
As of now the mod mainly features butterfly of different size and colors. You can also obtain Pollen Spirit eggs to summon an entity that will an 128x128 area around it from pollen falling onto grass blocks. This was done to maintain a better esthetic around your base.

Boss:

One summonable boss is available in the mod. Atlas. You can summon it by playing a carved pumpkin over two vertically stacked easterium blocks.

Thank you for reading this. Do not hesitate to ask any question about it.
Enjoy
