Fishman, not Manfish.
A 1 Gift Inhuman Physiology Power used by Tahm'Sehn, created by SamrinSamrin.
Tahm'Sehn possesses a pair of gills on either side of his neck that allow him to breathe water as a person does air: just like a fish. Additionally next to his eyes are a pair of additional slits that remain closed until Tahm'Sehn decides to use them, in which case they reveal a pair of milky glazed-over eyes reminiscent of that of deep-sea fish that allow him to see in lightless conditions, essentially darkvision.
This Power is passive and always in effect. Bonuses to Attributes and Abilities take the form of additional dice on the relevant rolls and do not affect Experience costs. As always, bonuses to the same dice pool from multiple sources do not stack, and the largest bonus is used.
Any Enhancements you take must be germane to the specific augmentation you've chosen.
