Not known for their intelligence the Gierach can be easily confused. These are again revenant type vampires. They look like hideous corpses with red eyes, long fangs and long claws. They smell of decay and earth. The Gierach spends most of it's time in it's coffin but it can venture out attack victims.
If you suspect a grave to have a gierach in it, lay a fishing net over it. The monster will have to untie all of the knots before it can leave to hunt. You can also spread poppy seeds or salt on it's grave for the same results.
The gierach leaves it's grave and searches for blood to consume. Like base vampires, it will drain 2 points of Con per attack. The gierach is not a subtle creature, it attacks with the purpose of feeding as much as possible and then getting back to it's grave.
The gierach is repelled by holy symbols, garlic and salt. Holy water can damage it and sunlight can kill it. It can transform into a large wolf or a large bat-like creature. A gierach reduced to 0 hp will become smoke and will return to its grave.
To destroy it you must find it's grave before noon and burn the body and clothing till nothing but ash remain. The ash must then be scattered. Failing to do so could result the gierach's return.
