I created/converted a DnD 3.5 Slaymate, water zombies, Zephyr hounds, iron skeleton and Adamantine skeletons all for my HARP Campaign (made it from level 1 to 14!)
Stats are available upon request...
(PS the slaymate has only one ability - to allow all who "possess" her to increase the undead Class level +1 for all created creatures (i.e. if you create a Mummy when "possess"ing one then it effectively becomes class 4 or 5 (for lesser/normal or greater). The same also goes for those you "control" too...
It makes it harder to Turn Undead, especially when confronted with a pack of the creatures...
