There are a variety of powers to earn in Starfield. From throwing fireballs, to creating a gravity well to suck in enemies. As well as being able to make creatures friendly and constantly regenerate oxygen for long sprint sessions. But one of the powers that is very well hidden is “Parallel Self” where you can summon a copy of yourself to fight with. While most powers are acquired through collecting every artifact, right up to the end of the game. This power takes doing a quest from one of the companions. Here is how you get the power.
How to Obtain Parallel Self in Starfield
First you will have to get Barrett back into constellation and he will eventually have a side quest to acquire his power for him. This will lead you to a temple where you will acquire this power. It really is that simple, but for those in Starfield who are blitzing through the powers to test out which ones they love. This information is just never conveyed to them. Frustrating completionists in that regard.
Once you acquire this power you will have to defend yourself against a Starborn but then that is the end of that quest. However, this is how you acquire the power. So, if you were having problems, I hope this helps you in Starfield.
