All animals are hostile to the target. Alternately, all animals see the target as a threat, either panicking uncontrolledly or attacking.
The target's wounds bleed. Any injury sustained by the target will continue to seep blood, dealing 1pt of damage per injury until magically cured or tended to with the Heal skill (dc 15 check to bind the wound).
The target is an unaffected carrier of a virulent disease, such as filth fever. The target himself shows no signs of infection, and Remove Disease has no effect on him (though Remove Curse works as normal). No matter what the normal vector and infection DC for a given disease are, they are now treated as Contact (with the character or something the character's been in prolonged contact with such as a bed), and the DC is the same DC as the original Bestow Curse that began the affliction. People subsequently infected can be cured by Remove Disease as normal.
The target's equipment decays. All items in his possession have their hardness reduced by 1 point per day. Once a given item's hardness is reduced to 0, it begins to lose hp at the same rate until it is destroyed. Magical items are not exempt, but an object must be in the target's possession for more or less the full day to be affected.
The target can only speak in Abyssal or Infernal. Symbols of good, holy ground, priests of good deities, etc harm the target as if they were an evil outsider that'd just been splashed with holy water. If the target is himself a priest of a good deity, they don't lose any of their spellcasting ability or cause themselves damage, but will have to make concentration checks when casting any spells that require a divine focus, as handling their own holy symbol will still burn them accordingly.
The target is treated as the undead with regard to spells and effects. Positive energy harms him and negative energy cures him. He can be turned, rebuked, commanded or controlled appropriately. Creatures uncomfortable around the undead are uncomfortable around the target. Undead Bane weapons deal extra damage to the target, and holy water burns them appropriately. On the up side, most un- or lower intellegence undead will not attack the target unless either he attacks them first, or they are expressly ordered to.
The target instantly spoils any food or drink they come in contact with, their touch blights plants and may sicken animals.
The target gains an inhuman craving for something - blood, vermin, human(oid) flesh, rotting garbage, bone marrow, etc. Normal food will no longer provide sustenance; only the substance in question can provide nourishment.
Anyone the target kills will rise as free-willed undead after a certain period of time has passed (a week, a day, on the next full moon, whatever). All affected should return as the same general type of undead - zombies, shadows, etc, and all remember who it was that is responsible for their return.
The target develops a second personality that takes control of their body when they sleep. The character still gains rest as normal. This new persona is evil and diametrically opposed to whatever the normal personality's goals are.
