I got it in my head that I'd like to make a Theno as patterned after a Siren. This would require the Naga tail to work, as they're classically sea snakes.

Naga already have traits to be sea serpents, so this shouldn't be too great a reach.

Additionally, Naga Vampires don't have the Nagatail shuffle. Could it be attached to that particular bodypart rather than to race/armour?

Why not make a naga with sea trait then. But other than that, sounds cool
