I'm disappointed that the White Wolf didn't publish any more rites than they did. I know that players like the crunchy bits (new Disciplines, cool new Dharmas, etc.). But even more so than Disciplines, I feel rites reflect the ritualistic and spiritual nature of the Kuei-jin. Only a few rites are featured here right now, but I'll add more as inspiration strikes me. If you have any rites or ideas to contribute, please send them my way; I'll add them to the list and give you credit.

The Rite of Jade Tea (Level One Chi Rite)
As with many jade-oriented rites, the Rite of Jade Tea was developed by the Korean Kuei-jin of the Green Courts. This rite helps them detect and secure supplies of jade.
The ritualist leaves a yellow jade or gray jade coin in a small bowl of spring water and recites a prayer above it, thanking the spirits of jade for their gifts. A Charisma + Rituals roll is made, difficulty of the local Wall. If the ritual is performed correctly, the Cathayan will find that the jade has dissolved in the water and formed a clear yellowish or gray liquid (depending on the jade used) known as "jade tea." Once the vampire drinks the jade tea, she will be able to detect and identify jade in her immediate vicinity (Perception x 8 feet) for the remainder of the night. A successful Perception + Rituals roll (difficulty 7) is sufficient to detect any jade present, with additional successes providing more information about the jade -- amount, nature (raw or worked), quality, location, type (red, green, white), etc.

The Rite of Jade Attunement (Level Two Chi Rite)
To perform this ritual, the vampire must recite a brief mantra just before sunrise, succeed on a Manipulation + Rituals roll, and place the jade item in her mouth (if the item is too large for this, she must instead cut herself open and put the jade inside her, which will likely cause at least one or two health levels of bashing damage). The ritualist then lays down at sunrise to enter Little Death, normally. When she awakens, the jade will be attuned solely to her. (At this point, the character no longer needs to keep it inside her.) No one can take advantage of the mystical properties of the item except for the character to whom the item is attuned, including storing Chi or using its special properties. A piece of red jade, for example, provides no good joss or special protection from magic except when used by the ritualist. Such a selfish act is normally frowned upon, but the Rite of Jade Attunement is being performed more and more often in Korea, where jade is becoming more scarce than anyone wants to admit...

Eye of Heaven's Mandate (Level Three Social Rite)
This rite allows a Kuei-jin to determine who have been branded akuma by the Rite of Infamy (below). (Note: this rite doesn't detect who does and does not serve the Yama Kings, but rather, those who have been subjected to the Rite of Infamy.)
This ritual is not performed lightly or often, only when a vampire has reason to believe an akuma is about, or a strange Kuei-jin presents herself in court. The ritualist cuts himself with a small silver blade and spends a point of Demon Chi; the spent demonic energy exits the body in a small green-black cloud. If no one marked by the Rite of Infamy is present, the cloud dissipates; however, if one so marked is present, the cloud wafts toward the akuma and envelops him briefly.

Chud (Level Four Individual Rite)
The Hun and P'o are always in opposition, struggling against each other for control. However, many vampires lose site of the fact that the Demon is as vital to advancement as the Hun, and that the struggle between Bone Soul and Cloud Soul makes advancement possible. Many vampires -- Resplendent Cranes and Rising Phoenixes especially -- neglect their P'o in favor of Hun, and don't seek to understand and assimilate their Demons' urges. For vampires that wish for accord with their P'o, and make up for past repression, there is Chud, also known as the Ritual of Being Devoured. This ritual is based on the powerful Tibetan Buddhist chud meditation. Rarely does a vampire feel it necessary to perform Chud more than once a year; overindulging one's Demon is even more destructive than repressing it.
The Kuei-jin must sit alone in a place where there are few distractions (a quiet room or waterfall are idea). The area should be relatively free from spirits, too, as the Chud is a private ritual. The vampire must achieve a state of deep meditation and maintain it for at least an hour (Stamina + Meditation, difficulty 7). The vampire visualizes herself as a receptacle, in which there are egoistic drives, oppression, lack of harmony, and imbalance. She also pictures her P'o as an entity separate from her (that appears either as a dark reflection of the vampire, or the character's Demon Shintai form if she has one); the Demon sits in front of her, waiting for its offering. The ritualist then mentally visualizes her skull slowly being sliced open, starting at the forehead and going counter-clockwise around her head until the incision meets in the middle. (The ritualist can picture a blade of air, a sword, a saw or whatever as the implement doing the cutting, but it must be a clean and steady incision.) This ritual isn't painful, but it is intense, and the vampire must make a Willpower roll (difficulty 8) to picture this with the proper intensity. Once her skull has been cut open, the ritualist imagines herself removing the top section of her head and holding it in her hands like a bowl; within the bowl is the character's Ego. She offers this bowl to the P'o, who takes and eats of it, symbolically devouring the character's oppressive Hun. When this is done, the P'o sits in the "bowl," the vampire puts it back on, and the Demon returns to its rightful place in the Kuei-jin.
While the visualization of Chud is disturbing to say the least, those who perform the ritual find it to be refreshing and liberating. The P'o is sated, the Hun is humbled, and a sense of profound calm fills the vampire for a few night or so. Upon completion of the Chud ritual, the character gains one point of Demon Chi (which can take her above her P'o rating if she is already at maximum, but in this case the extra point lasts only for one night). For a number of nights equal to the success on the above Willpower roll, the vampire's P'o is more forgiving, and is less likely to provoke Shadow Soul, Fire Soul or Wind Soul. Moments of Den tend to come more easily, while Acts of Blindness are less cataclysmic. These things are more given to roleplaying than systems, but the Storyteller may rule that one less die is rolled for the P'o during this time. This doesn't give the vampire free reign to go out and do as she pleases, however; such acts of hubris would enrage the P'o (as the Hun apparently learned nothing), as well as having probable Dharmic repercussions.
Some spirits claim to have seen this ritual performed from the spirit lands (at a safe distance, of course), and that the ritual involves more than visualization. They say that the P'o actually separates from the vampire, and the spiritual reflection of the vampire literally performs this gruesome self-surgery. The veracity of this claim is unknown, and most vampires probably wouldn't care. It is enough that the ritual works.

The Rite of Purification (Level Four Social Rite)
This ritual is used to dispel the spiritual mark left by the Rite of Infamy (see below). A character can't use this rite on himself; he must find someone of proper enlightenment (i.e., of equal or greater Dharma rating) willing to use the Rite of Purification on him. Not many Kuei-jin are willing to perform this rite without the okay of their court's ancestor, especially for some akuma they don't know.
The ritualist must wave smoking incense over a piece of white jade, and leave it where the sun will shine on it for at least a few hours (the ritual is ruined if it rains, or if it is overcast all day). The next sunrise, the subject of the ritual swallows the jade. After a few minutes, the subject feels searing pain as the sunlight stored in the jade burns away his spiritual impurities; the character takes one level of aggravated damage (which can't be soaked by any means) and must roll to resist Wave Soul. Then, assuming the vampire succeeded on his Virtue roll, the ritualist takes a ritually prepared blade and cuts the stone out of the subject's gullet (causing lethal damage; while soak is rolled against this, the subject must endure at least one health level of damage before the piece of jade can be removed, which may take some time for especially tough vampires). The jade, now removed from the vampire, is now warped and black, stained by the subject's evil; the subject must take this defiled stone and destroy it in front of the ritualist.

Losing and Relearning Powers Vampires don't actually "forget" the Discipline powers they lose when making artifacts. The power, and the ability to use it, is transferred from the vampire to the target item. When a vampire loses a Discipline power this way, he must learn that power again in order to use it himself, but doing so costs only the power's level x 4 in exp and takes half the normal time. Note when a vampire loses a Discipline power, he loses only that power, not the entire Discipline, and the Discipline's total level does not decrease. Exception: In the cases of linear Disciplines, such as Black Wind and Iron Mountain, each dot invested in the item counts as a separate power, and while the overall Discipline level decreases, the character buys back the lost dots at a cost of new rating x 4. For example, if a Bone Flower with Bone Shintai ●●●● and Black Wind ●●● empowers a katana with Bone Obedience (Bone Shintai ●●●) and two dots of Black Wind, he loses the Bone Obedience power, but he still has Bone Shintai ●●●● and the powers Corpse Skin, White Tiger Corpse and Five Poison Cloud. He also drops to an effective Black Wind ●. If he wants to increase his Bone Shintai or Black Wind ratings, he must raise them at x 8 exp, as normal (though he doesn't gain the full range of those Disciplines' powers until he buys those powers back). To "buy back" the Bone Obedience power, the vampire must spend 12 exp (3 x 4); buying back both dots of Black Wind will cost 12 exp (4 exp [1 x 4] to raise it from to 2, then 8 [2 x 4] to raise it from 2 to 3).

Empower Artifact (Level Five Chi Rite)
This rare rite allows a Kuei-jin to create magical artifacts, though doing so is costly both spiritually and in resources. Not many have the requisite dedication to create magical items, as the vampire loses whatever powers he invests in the item and must relearn them.
The player informs the Storyteller the type of artifact he wants his character to create. The Storyteller assigns a level to the artifact as a rough measure of its power; use existing artifacts, including those listed on my artifacts page, as guides. An item can have no more powers or special properties than its level. A character can only create artifacts of a level up to his Dharma rating, which means a character must attain a certain level of enlightenment before he can churn out really powerful items.
The item the character is to enchant must be clean and of high quality; jade, metal and bone in particular make good receptacles for magic. The vampire must perform an hour-long ritual over the item every night for one lunar cycle, starting with the new moon; any missed rituals forces the vampire to start the ritual over again. When the second new moon arrives, the vampire must anoint the receptacle with a mixture of powdered jade and blood, and invest a number of Chi in the item equal to the level of the artifact (the type of Chi required depends on the nature of the item; Yin for an amulet that protects the wearer from Spectres, Yang for a wooden staff that can change shape, and Demon Chi for a weapon that inflict horrific wounds). The vampire must also invest in the artifact the Discipline powers and/or rituals that he wants it to have. In so doing, however, he loses those powers. The vampire can relearn "lost" Discipline powers at reduced cost (see below).
At this point, the item is now a magical artifact. Its specific capabilities are up to the player and Storyteller, including incidentals such as activation costs and method of use, but should be based on the powers/rituals stored in the item.

Rite of Infamy (Level Five Social Rite)
This rite is used upon a Kuei-jin who is to be declared akuma. Though there are more than enough genuine akuma, more often than not in recent nights the Rite of Infamy has been used for political purposes or to get rid of unpopular vampires. However, there are tales of vampires who have used this rite too often or for selfish purposes, and were themselves revealed to be akuma by the very rite they sought to use against others. Whether these stories are genuine, or merely wishful thinking on the part of maliciously persecuted victims, is not known.
The would-be-akuma must be present for this rite to be enacted, and the lead ritualist must publicly lead at least four other vampires in performing the rite. The lead ritualist can't lead this rite against a vampire with a higher Dharma rating than herself. The lead ritualist rolls Manipulation + Rituals (difficulty 8).
In addition to making the victim a social outcast, this ritual leaves a spiritual mark on the subject that those with Eye of Heaven's Mandate (see above) can perceive. The mark lasts for a length of time determined by the successes rolled by the lead ritualist:
1 successes: eight nights
2 successes: eight weeks
3 successes: eight months
4 successes: eight years
5 successes: eight decades
