Tower of Fantasy’s summoning system hinges on a very simple set of tokens called Nuclei that you can find dotted all over the world. There are two different types of Nucleus Cache, Black and Gold, and they have their own set of tokens to spend on spinning them. There is also the exceptionally rare Red Nuclei, but they’re used for the speciality gacha. We have a full Tower of Fantasy currency guide if you need more information.
As you may expect, Black is more common than Gold, but you can still find plenty all over Astra if you know where to look. You can take a look at this pair of maps to see exactly where you can find all of them on Astra.

You can collect them primarily from interactable objects and locations in the world like Tar Pits or Kerosene Plants, but Gold nuclei are usually in much tougher locations like Strongholds. There are also different Caches you can find out in the world, Purple Caches indicate Black Nuclei, while Gold Caches will give you both Gold Nuclei and Dark Crystals.
Bare in mind that some locations will require time after activation before they yield any Nuclei, and we recommend keeping a fire weapon on hand to make the process go smoother. It’s also possible we’ve missed a few spots on this map, but what we’ve marked out should give you more than enough to get started.
