❤Welcome❤ to the guide on how to obtain crystals to craft the components of the nuclear skull (Crystal fluid, fission device) and be able to throw ☠nukes☠ at those that fall on you evil from the neighbors and friends bar!

1#
The easiest way is to put crystals in the wish list, you can only place 3

The other way would be by colonizing 6 planets of the following colors: red, blue, green, white, purple, yellow.

Note: The blue planet even though it looks white on the outside, its obstacles are mostly blue.
To colonize all the planets you must have a level 5 observatory, you can slowly improve it and colonize each planet in each new level There is no rush!
Once you have colonized a color you will see that a strange crystal grows on the planet which is the same color as the galaxy (it counts as an obstacle and comes in different sizes) you must recycle these crystals to have the probability to obtain a crystal of the corresponding color.

Finally and extra, to obtain the starling Kettle, it is very simple, well, not so much, you must destroy star bases of level 4 or higher, this item has a very low drop rate

Good luck in the galaxy! 💪
