An iku-turso's bite inflicts a strange, supernatural disease called tursas. This disease causes the victim's skin to grow painfully scaly, causes strange hallucinations, and eventually transforms the victim into an iku-turso.
As long as a victim suffers any ability damage from tursas, it gains the ability to breathe water. A creature reduced to 0 Charisma by this disease transforms into a fully grown and healthy iku-turso—it immediately forgets its previous life and abilities and seeks out the nearest iku-turso community to join it. A wish or miracle can reverse this transformation. The save DC is Constitution-based.
As a standard action, an iku-turso can call forth a few small points oflight, functioning like a dancing lights spell (CL equals the iku-turso's HD) except as described here. Creatures within 100 feet of one of these lights must make a DC 18 Will save upon sighting them or be compelled to approach them by the safest and most direct path. A creature that successfully saves is immune to the same iku-turso's light lure for 24 hours. If a subject of this effect has to move through hazardous terrain to reach the lights, that subject receives another saving throw to end the effect before entering the hazardous terrain. This effect ends once the character reaches the light or takes any form of damage. This is a visual mind-affecting charm effect. The save DC is Charisma-based.
