You can create and control long astral needles with precision at up to 50mph. When a needle is piercing someone you can access and harvest something from their mind. This could be a memory, skill, personality trait, or anything else that is purely mental. You can then inject what you took into yourself or someone else. You can remove and insert partial aspects, such as taking hatred toward something and putting it into someone else tied to something else. You can only interact with aspects of the thinker's powers that would remain even if the Parahuman's power was nullified.
Your needles can access the corona of pierced parahumans. You can harvest and inject traits of powers, such as methods of control, power-granted senses, and other such things.
