Hi, I am creating a group of NPCs that are aliens with a tiny bit of human DNA (they ancestors used human DNA to save the race thousands of years ago) that race is human-looking with the only distiction that they are blue-skinned
so.... these is group lives on Earth, and I was thinking that they have a chemical substance that can change they skin from blue to a human coloration, they just need to take a "shot" of it and the skin changes. However, power activation would cause the skin go back to blue.
So, I was thinking that this could be some kind of equipment rather than a device, that grants something like a quick-change feat and a disguise bonus??? Just to note: you need to take a new dosage of the substance to get back the effect, and it takes a entire round for the transformation to be completed.
