Astral Seed + Fusion

[Darg]

Fusion doesn't say you are a being of one mind and flat out says that one or the other has control over the body. I would say Astral seed would require 2 casts, one for each mind who casts in control for both to benefit. Putting it a different way memories and experiences fuse as that is a physical aspect of your brain, but the conceptual aspect of you is not fused.
