A to Z of Vampires: Yara-ma-yha-who

Let's head to the land down under for one of the strangest vampires I have found.

The Yara-ma-yha-who is a vampire of the aboriginal peoples of Australia.

It appears as a small red man with a large mouth but no teeth.  He lives in fig trees and jumps on people as they walk by attacking them with his sucker tipped fingers.   The Yara-ma-yha-who will then suck blood out the person unless he is flung off.  Each attack by the Yara-ma-yha-who makes the person a little shorter.  The attack drains 1 point of Constitution while attached.  A successful grapple role is needed to remove it.

Anyone drained to death by this creature will become one. The Yara-ma-yha-who will open it's wide mouth and swallow the dead victim whole.  It will sleep and then regurgitate the victim who will be small and red like the Yara-ma-yha-who itself. It will rise by the next dawn as a new Yara-ma-yha-who and must find a fig tree of it's own to haunt.

Unlike other vampires the Yara-ma-yha-who hunts during the day and sleeps at night.

Reducing the vampire to 0 hp or turning it will cause it to flee to it's tree.
The Yara-ma-yha-who can only be destroyed is by staking it int he heart with wood from  it's own tree and then then burning it and it's tree.

A Yara-ma-yha-who cannot enter a personal dwelling or holy land at all.

1 Descending and [Ascending] Armor classes are given.
2 This is used for Basic games, and S&W. Also for monsters that I think need to save a little differently than others.
3 Morale is "Basic" Morale and based on a 1-12 scale.
4 Have not decided yet if I want to use 3.x style undead Constitutions or not. (15) Reflects what their Con would be if I do use it.  I might just put a number in () like I do for Ghosts of Albion.
5 obviously more reflective of personality and character than looks.

I am working on a monster stat block that I can use in my old-games and future publications (if I do any).  I want something that anyone can pick up and use regardless of the system they are using.
What do you think?
