I have this weird feeling there's a regular siren we should base this from. Or am I remembering wrong?
At least according to Echohawk's index, there is not one.

Sirine yes. Siren no.

Anyway, I think we can use some inspiration from the harpy.

Originally appeared in Requiem: The Grim Harvest (1996). This is the Monstrous Compendium Annual Volume Four version.
Ravenloft sirens are immune to sleep¸ charm, hold, poison, and death magic.
On the Prime Material plane, Ravenloft sirens are turned as wraiths. When turned, they flee back into the sea, disappearing beneath the waves.
I'm not sure it needs the +6 Str from vampire spawn and +2 from merfolk; I'd be happy with just Str 16. But the rest looks fine. I'm not sure I'd call the disguise "beguiling," but it's sure something!
I'd rather boost the claws to d6 than raise the Str.
"Veil of Deception" is a wonderful name, and the ability is looking pretty good.![]()
