Venomous Blade

By means of this spell, a priest can enspell a single bladed weapon so as to envenom the wounds inflicted by the three first successful attacks with the blade. Any creature so wounded automatically suffers 1 additional point of damage per round in subsequent rounds until the wound is bandaged or 10 rounds (1 turn) expire. Successive wounds damage in the same manner as the first. The spell fades after three attacks or 24 hours expire, whichever comes first.

Like wounds inflicted by a sword of wounding, injuries caused by a venomous blade cannot be healed by regeneration nor by potion or spell short of a wish. Damage usually can be healed only by natural means – rest and time. However, the underlying magic that prevents the wounds from healing can be removed by an entire elixir of life or a cure disease from a 9th level caster. After either measure is employed, the impediment to magical healing is removed.

The material component is a poisonous sludge of venoms and other noxious ingredients that are smeared on the blade during the casting.
