Any humanoid creature that is slain by a wight becomes a wight itself in only 1d4 rounds. Spawn so created are less powerful than typical wights, and suffer a -2 penalty on all d20 rolls and checks, as well as -2 hp per HD. Spawn are under the command of the wight that created them and remain enslaved until its death, at which point they lose their spawn penalties and become full-fledged and free-willed wights. They do not possess any of the abilities they had in life.
