Morurun Curse

About
The Morurun Curse refers to a collection of curses that are cast by the Kalar race. There exist many types of Morurun curses that can do all sorts of things, such as instant death, a long and painful death, mental effects, status debuffs and others.

Some types of higher order curses may only be cast by the Kalar queen, whose curses cannot be broken by anyone other than the Kalar queen herself. Below is a non-comprehensive list of curses seen.

Abstinence Morurun
This curse can only be inflicted on men and causes them to be unable to have sex, by preventing their penis from getting erect when touching a low-leveled woman. They will only be able to have sexual intercourse with women that are level 35 or above and after ejaculation the woman will lose all her levels, dropping back to level 1. This applies to any type of sexual activity performed with the penis, be it vaginal, anal, oral sex and even handjobs. To further add to the frustration, the victim will still feel the same sexual arousal they would usually feel, just having the physical restriction to do anything with it.

During Rance Quest, Rance gets afflicted by this curse.

Munniegon Morurun
This curse causes the victim to gain a need to eat gold. They do not wish to eat gold, but the curses forces them to do so. If they are unable to consume enough within a certain period of time, the user becomes sickly and pale-looking. They may also begin losing their minds.

During Rance Quest, Shacho Amazusa gets afflicted by this curse.

Diffusion Morurun
This curse causes the victim to begin projecting their inner thoughts and feelings, so others nearby can hear them. The effects of the curses may be embarassing for the user, but also may be annoying or debilitating to those who hear the victim's thoughts.

In Rance Quest, Kanami Kentou, Kaito and many others get afflicted by this curse.

Massive Morurun B
This curse, that can only be performed by the Kalar queen, kills all human men within a 10 kilometer radius. It requires time to be cast. However, it appears this curse may sometimes bring someone on the verge of death, but not kill them. It is unknown why this happens.

Trivia

 * It is not possible for a person suffering from a curse to get afflicted by another. However, the curse may be overwritten if it is of a higher order.
 * According to the skill description of the Abstinence Morurun in Rance Quest, the curse is said to originally be used for castration of livestock.
 * As rare as the Abstinence Morurun is, it seems to be a curse that has been seen used on humans in the past, as Crook Mofus knew about it. She was the one that explained most of the machinations of this curse to Rance. She also claimed that if the victim didn't perform sexual activity for too long, he would turn homosexual.It is unknown if this is real or merely a joke from Crook.
