The necrophidius is created for two reasons—guard or assassin. It will always be found performing one of the aforementioned tasks.

   It appears as the skeleton of a giant snake topped with a fanged human skull. Small white pupils can be seen in the eye sockets.



The necrophidius, if it surprises its opponents (and if it itself is not surprised) will use its dance of death to entrance its foes. Afterwards (or instead of, if there is no surprise) it uses its bite attack.

   Dance of Death (Ex.): On the first round of combat, if it surprises its opponents (and if it itself is not surprised) all within 30 feet that view the rhythmic swaying must succeed at a Will save (DC 10) or become entranced and unable to take their eyes off the necrophidius for 2d4 rounds. A victim can take no action while entranced. This allows the necrophidius to advance and attack with a +4 bonus to its attack roll. The target loses its Dexterity bonus to AC while entranced.

   If the necrophidius successfully bites its opponent, the victim can attempt another Will save with a +4 bonus to break the entrancing effect.

   Paralysis (Su.): Bite, Fortitude save (DC 11) or paralyzed for 1d6 minutes.

   Construct: Immune to mind-influencing effects, poison, disease, and similar effects. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage. Necrophidius’ have darkvision with a range of 60 feet.

   Immunities (Ex.): Because it lacks flesh or internal organs, a necrophidius take only half damage from piercing or slashing weapons.

   Skills: The necrophidius receives a +12 bonus to all Move Silently checks.



A necrophidius’ body consists of a human skull and the skeletal remains of a constrictor snake.

   The golem costs 15,000 gp to create, which includes 500 gp for the body. Assembling the body requires a successful Craft (sculpting) check (DC 20).

   The creator must be 14th level, and be able to cast arcane spells. Completing the ritual drains 1,000 XP from the creator and requires charm person, geas/quest, hold person, limited wish, and polymorph any object.



The Necrophidius first appeared in the Fiend Folio (1981).
