Alcort

The divine spell known as Alcort works exactly like the later britannian spell Cure.

During the time of Exodus, poisonous creatures were especially dangerous and their poison could quickly spell doom to an adventurer. Since a healer usually was too far, the clerics of the land used this spell to compensate for it. Casting it, all poison is removed from the body, restoring the patient's health. Note however, that it only removes poison. It doesn't heal wounds.
