Regeneration (Necromancer Ability)

The necromancer is able to regenerate two hit points per round. This ability continues to operate regardless of circumstances. Severed limbs continue to twitch and move under the wizard's direction, and they immediately reattach if brought into contact with the body (similar to a troll's powers). The wizard's body continues to regenerate after death, even if the remains were destroyed and reduced by fire or acid. If the body is dismembered and the parts buried separately, it will take the necromancer one month to regenerate completely for every 100 feet distance of separation between the various parts. Alternatively, if the body is burned or dissolved in acid, the remains may be scattered over a wide area, delaying the regeneration time by one month for every 10-foot-square region of disposal area.
Necromancers with such regenerative powers can be terribly difficult to kill permanently. The DM may care to devise a special ritual (or a minor adventure) which must be completed in order for the wizard's death to be final. For instance, a certain necromancer's remains might need to be dissolved in aqua regia and then cast into the Lake of Winter Spirits during an annual solstice. Another wizard might keep his life force safe in a receptacle or phylactery which must be destroyed before the necromancer can be killed. Certainly the rite of final destruction will vary from necromancer to necromancer and must be adjudicated by the DM.
