One of my favorites from the 3.5e XPH, this is an undead composite of the minds of dozens or more victims who died together in terror. Also an awesome mini sculpt!
true story: I had a 1st ed fighter 16th level with a hippogriff mount until a DM had the BBEG set up a wall of force that was set horizontally and sliced the hippogriff in half and cut off his feet. My fight4er would not be defeated though, had the cleric come to his aid so he could keep fighting.
The party was up against Asmodeus so when the cleric regenerated his feet, they came back as goat's feet.
