--- Implant (Su) When a ghostflower seed reduces a living creature to 0 or fewer hit points with its incorporeal touch attack, the seed implants itself in that creature's flesh, becoming an inert object instead of a creature. For as long as the seed remains implanted, it siphons nutrients from the victim's body; the victim begins to starve, no matter how much food the victim consumes. A remove disease spell (or similar effect) rids a victim of all implanted seeds, or they can be cut out one at a time with DC 20 Heal checks (each attempt takes 10 minutes). If a check fails, the healer can try again, but each attempt (successful or not) deals 1d4 points of damage to the patient. If a creature dies while implanted with ghostflower seeds, a ghostflower plant will grow from his grave. Except for the seeds it will eventually produce, this plant is harmless.
Produced by magical flowers that grow only on graves, ghostflower seeds begin life as small, fibrous puffs. Soon after being released from their parent plant, these seed puffs rarefy and expand, becoming balls of incorporeal light that bear a striking resemblance to will-o-wisps. In this form, a ghostflower seed is willfully mobile, seeking out a living creature in which to plant itself. Once successful, the seed becomes an inert object inside its victim's body, feeding off its host until its host dies, perchance to germinate in its host's grave, producing a new ghostflower plant.
