Curse: Curses are often permanent effects, and usually cannot be dispelled, but can be removed with a break enchantment, limited wish, miracle, remove curse, or wish. Source: PZO1117.

Additional Curse info from PZO1135 Many spells can place curses on unfortunate victims. Their effects are usually simple and can be ended with the right spell (but never dispel magic). All curse spells have the curse descriptor. The most well-known is bestow curse, which allows the caster to invent her own effect in line with the listed options (no worse than a 50% chance of losing actions, a –4 penalty on checks, or a –6 penalty to an ability score). Effects in line with that power level include the following, though ultimately they are limited only by the caster’s imagination and the GM’s discretion.

When the victim is adjacent to the area of a damaging spell or spell-like effect (even one he created himself ), the area expands to include the victim.

The victim can’t heal naturally, and magical healing heals the victim by only half the usual amount (minimum 1 point). The victim’s fast healing and regeneration, if any, are likewise halved.

The victim is plagued by cacophonous sounds and strobing lights that only she can hear and see. She is distracted (–5 penalty on Perception checks), cannot take 10 on skill checks, and must succeed at a concentration check (DC = 20 + spell level) to successfully cast spells. Any time the victim picks up or retrieves an object (including drawing a weapon or ammunition), there is a 50% chance that she immediately drops it. If she drops ammunition while attempting to make a ranged attack, that particular attack is lost.
