About this Mod

.
Inspired by American folklore, polynesian culture and avant-garde art, The Call From Rapa Cosmo is an advancement-driven psychedelic adventure where you can meet and trade with omniscient extraterrestrial beings for powerful cosmic artifacts as well as share spiritual moments.

The VBI (Villager Bureau of Investigation) is fascinated supernatural and paranormal events and will get you immensely rich if you help them get their hands on powerful extraterrestrial objects.
Although villagers seem harmless, Agent villagers will provide you the tools for you to help them reach their goal.

The mod adds a whole advancement tree, 5 different structures, a new villager profession, a new creature with its own unique trading system, a customisable weapon, a full armor set with related items and a new hat, 9 alien artifacts, multiple block sets, new paintings as well as 3 new music discs !

In order to start the mod's story, you have to sleep and have an unexpected vision.
Once you had the dream, you must build a Radio Beacon, sketch of the structure you must build with required materials is provided to you, if you lose the sketch you can still find a clear photo of said radio beacon here !
Warning : If you want "the event" to happen once you started the radio beacon you have to wait until the dawn (approx. tick 23299), sleeping will skip the arrival and you will have to wait for the next day's dawn.
Once you meet the beings from Rapa Cosmo, they can give you artifacts for the price of 30 experience levels. Each artifact can be bought only once in a world however they also sell 16 Space Metal Blocks for 5 experience levels, this trade does not run out.

/!\ If you kill even only one of the aliens, the trading system will be forever locked for you.
(Don't worry, killing one is not a piece of cake.)

.

.

Aliens have a regeneration bonus when they are in contact with Space Metal that isn't weathered or rusty and just like the blocks, will appear "RGB" ( a color from outer space the player cannot comprehend)
However if all 9 aliens are killed, Space Metal will begin to wear out and the ship will progressively turn into a hunk of rust worthy of a modern art exhibition.

(Note that the mod's "storyline" has some steps that must be done in a particular order, some isolated item cases have currenty no effect)
