Most Pokemon in Pokemon Legend: Arceus require you to progress further in the game in order to unlock them. Some Pokemon will only be available once you complete and finish the main story. However, this guide will show you how you can catch Abra very early on in the game.
Abra Location — Pokemon Legend Arceus
Abra is a psychic-type Pokemon and is considered a Psi Pokemon. You can find this Pokemon with Synchronize, Inner Focus, and Magic Guard Ability. Abra is weak to Pokemon with Bug, Ghost, and Dark-type moves.
Abra will evolve into a Kadabra when it reaches Level 16. You will need the Linking Cord to evolve Kadabra into Alakazam.
When you first get to the Obsidian Fieldlands, you will spawn in the Fieldlands Camp.
Progress more into the story to unlock the Heights Camp in the area. You will find Abras in the Windswept Run area in Obsidian Fieldlands. It can be challenging to catch an Abra because it will teleport away when it notices you.
One way to catch an Abra is to get a Spoiled Apricorn and throw it at them. This will stun them and you can then throw your Poke ball to catch the Abra.
Whichever way you choose, I wish you luck!
