All Astromons that appear in adventure areas except during boss rounds can be caught using Astrochips. Astromons caught in this way will be in their pre-evolved state. You can make up to 3 attempts to catch an Astromon in one set of battles, and Astrochips can be automatically refilled before battle. If you fail to catch an Astromon the first time, your chances will increase the next time you try. However, if you defeat the Astromon, you will be unable to catch it. Catching some Astromons will give you rewards, make sure to collect them!
Special Encounters[]
Sometimes you will encounter special Astromons during your adventure. When you find a Variant, rare, super rare, or legendary Astromon, your Astrogun will detect it and stop the battle, even when auto-battle is enabled. These Astromons appear much less often than regular Astromons, so try to catch them whenever possible!
Astromaster's Association (Capture League)[]
