Curses
Curses are the result of an imbalance in the world, a foolish tilting of karma that brings misfortune down upon an incautious adventurer. Sometimes the result of careless actions, curses are at times believed to be a type of justice, the Fates balancing things back out after misdeeds send the world askew. Of course, it is just as likely for a foolhardy adventurer to find himself cursed after crossing a grumpy sorcerer or carelessly trying on a mysterious item of clothing.
Targets of Curses
Curses come in many flavors, some intentional, other accidental. Each has different requirements for lifting their afflictions. Curses can also affect a variety of subjects, from people to items to the land itself. The following are a few of the targets who can be afflicted by a curse.
Magical Items
Sometimes mages bend the realm of reality to infuse magical properties in an item. If this tricky process isn't done correctly, the items may come out twisted and wrong, attached to the wrong type of magic. These items are often disguised as beneficial items and are hard to dispense with once acquired. A Remove Curse spell will likely aid in taking cursed items off, but nothing short of a wish spell will actually lift these curses.
Creatures
Individuals can be cursed as well. Sometimes these curses are the punishment of the gods, the result of deeds that run afoul of some deity's divine will. Such curses are often hard to remove, as they require setting oneself right with the offended deity, usually through some sort of atonement or recompense.
Other times these curses can simply be laid at the whim of a witch or wizard. By comparison, these curses are fairly easy to remove and can be done entirely through magical means. People can also find themselves the recipient of cursed afflictions such as Lycanthropy. These can be cured, but usually only through a special process that helps root out the affliction and return the victim to normal.
Regional Curses
Land, tombs, bodies of water, or other terrain can be afflicted with curses that in turn bring misfortune to those who foolhardily pass through them. A battlefield scarred by traitorous bloodshed, a defiled tomb of a sacred priest, or a house marred by tragedy can all carry their own types of curses. Such curses often bear the signs of natural and supernatural aberrations--unusual weather, supernatural darkness, a lack of plant or wildlife, or haunting by supernatural beings. Removal of these curses can be tricky. Often the source of the curse itself must be dealt with. A wrong must be righted in some way, restitution made. Afterwards, at the source of the curse, a Remove Curse spell can seal this atonement, lifting the blight on the land. This is done in the same way arcane curses are lifted.
Mundane Items
Mundane items can also be attached to misfortune, usually through the Bestow Curse spell or other means. These items have no special magical quality, but they will bring a curse down upon anyone who possesses them. Usually these curses go undetected and it is difficult to identify the exact item carrying the curse itself, since these items do not register on a detect magic spell. However, unlike cursed magical items, mundane cursed items are easily taken care of with a Remove Curse spell.
Sources of Curses
Arcane Cursing (Bestow Curse)
Some people who run afoul of a magic user and receive a permanent affliction because of it, usually through the Bestow Curse spell. These curses can only be lifted by casting Remove Curse at a comparable level as the Bestow Curse spell. The caster removing the curse also needs to make a successful spell attack roll against the curse's DC. Bestow curse can also curse a mundane item, causing it to bring misfortune to any who possess it.
Magic Item Mistakes
Binding magic to physical objects is a tricky business that requires not only altering the fabric of reality but coaxing such magics to remain in existence permanently. This complicated process requires an experienced hand, though even with training, things can still sometimes go wrong. When a crafter misses his item creation check by 10 or more points the item becomes cursed. Sometimes this creates an entirely different item, usually one slightly more malevolent than intended. Other times the magic infused in the item is dark and twisted, punishing those who use it. Most often, cursed items appear normal and only through extensive use are their true natures revealed. Wearable items are often identified as cursed when the bearer attempts and cannot remove them. These items can only be removed after successfully casting Remove Curse. Short of a wish or miracle spell, there is no way to remove the curse from magic items.
Aberrant Behavior
Sometimes an individual's misdeeds incur the wrath of a divine or cosmic power. Out of divine justice, these individuals are inflicted with a scourge, a special curse that cannot be lifted until complete atonement and retribution is made. Only then can the curse be lifted with a Remove Curse spell. Scourges can be inflicted by a divine representative through the scourge spell, or by a deity itself.
Other more sinister aberrations also exist, though, usually created from some extreme and traumatic event--a child left to perish from the elements, a drowned lover, a stillborn baby cast out without a proper burial. These wronged beings often become cursed creatures who exist to bring retribution to those who harmed them. Usually, the only relief for such beings is peace to be found in the afterlife, though some afflictions do have complicated and effective cures.
Afflictions
While sometimes curses come about through foolish or unnatural behavior of the victim, some forms inflict themselves on the innocent or unwary. These cursed afflictions are in ways akin to diseases. Lycanthrope, mummy rot, and even vampirism fall under these categories.
Hexes
Witches have access to a variety of magic tricks called hexes. Some hexes can inflict small curses that inconvenience or weaken their foes. Hexes can sometimes be long-lasting, though usually they last a much shorter time than a traditional curse.
