WOTC R&D, Dragon #300
A wight's appearance is a weird and twisted reflection of the form it had in life. Its wild, frantic eyes burn with malevolence. Its leathery, desiccated flesh is drawn tight across its bones, and its teeth have grown into sharp, jagged needles.
Wights lurk in barrow-mounds, catacombs, and other places the thick with the aura of death where they nurture their hatred. They seek to destroy all life, filling grave yards with their victims and populating the world with their horrid progeny.
Creating a Wight
"Wight" is a template that can be added to any corporeal creature except constructs, oozes, and undead, refered to hereafter as the "base creature").

Hit Dice: Change to d12
AC: The base creature's natural armor increases by +4.
Damage: The base creature's natural and manufactured weapons deal damage normally. In addition, one of the base creature's natural attacks now causes energy drain. If the base creature does not have a better natural attack, it gains a slam attack that deals damage based on the creature's size:
