Hamund Handbook Volume 1
Adventuring Gear
Very Rare
This roughly basket sized crystal generates a 150-foot radius
field of negative energy that disrupts the natural flow of life in
the area. While in this field, creatures cannot regain hit
points, and any humanoid that dies inside it rises one round
later as a zombie. This field passes through all solid objects
except a layer of silver that is at least 1/2 inch thick. This
crystal cannot be deactivated and only stops functioning if it
is destroyed.
The crystal has 30 hit points, 15 AC and is immune to
poison and psychic damage.
Cost: 20000 gp
