I has been a good while since I came up with another specialist and I had the thought of a branching promotion specialist tree. So instead of just getting the option to promote to a king you could promote to some other specialist also. So I came up with a diffrent promotion for the hypnotist and here is what I came up with.
Illusionist
Promotes from hypnotist
Local: After an opponents sub engages in combat at an outpost you may launch a sub showing the exact same contents of the sun that was just engaged in combat with the illusionist. This sub does not take part in combat and disappears after it reaches its target.
