The Sept, the order of Gnostic vampires of which Iris has been a member since her death, have priests who practice a form of what is, essentially, magic. The study of these "Gnostic Miracles" has been one of the major focuses of Iris's requiem ("requiem" being the fancy word for a vampire's "life" after their death/embrace). Mechanically, for those familiar with Vampire: The Requiem canon, Gnostic Miracles are more or less identical to Theban Sorcery; however, a few rituals have been modified in name and/or flavor to better suit the Sept.

Each "miracle" is accomplished via knowledge of its ritual components and an act of will; technically, an academic understanding is more important than faith in getting it to work. (Granted, because of Gnosticism's emphasis on, well, gnosis — which is to say, transcendence through knowledge — Sept priests and scholars might argue that faith and understanding are closely linked.) In terms of flavor, a miracle uses a ritual offering to invoke the principle of "as above, so below." The offering is consumed, and the miracle takes effect, with the speed with which this happens and the duration of the effect usually dependent on the skill of the sorcerer miracle worker.

Mechanically, performing totally not Theban Sorcery a Gnostic Miracle is accomplished with a pool using Intelligence + Academics + Theban Gnostic Miracles, and by spending a point of willpower and the ritual's attendant offering.

Iris is an extremely skilled "miracle worker," capable of producing very powerful effects. She knows how to invoke the following "Gnostic Miracles":

• Level 1: grant resistance to the ecstasy of vampire bites; create temporary mystical armor from vampire blood
• Level 2: give herself a powerful, unearthly presence; summon a bird made out of a person's sins to attack them; cause someone to speak in tongues for hours; cause someone to, for a scene, spew white moths from their mouth if they lie; grant a second (potentially empowered) chance to resist a supernatural power
• Level 3: grant a (melee) weapon a number of empowered, blessed attacks
• Level 4: telekinetic chain lightning-esque attack
• Level 5: for a heavy personal cost, set all visible targets who have committed a named sin on fire; infuse an area with a virtue such that all who visit temporarily gain that virtue

More detailed explanations, with flavor and, for those who are interested, mechanics, below:

Level 1 Rituals

• Celibacy: Grants a mortal instinctive resistance to the the "Kiss" (the ecstasy that comes from being fed on by a vampire) — the subject automatically reacts with alarm to being bitten, no matter how cleverly the vampire conceals the act, and is granted a stronger resistance to succumbing to the pleasure of the bite.
  Mechanically: activation successes grant +dice to standard Resolve + Composure roll to resist the Kiss
  Offering: the subject's sweat (can be used simply with the sweat naturally on the subject's skin)
  Vampire the Requiem - Covenant: Lancea Sanctum p. 194


• Hauberk of Blood: The miracle worker smears, splashes, or even paints designs using vitae (vampire blood) on the subject, empowering the blood as a mystical shield against damage. The more blood used in the hauberk, the more significant the damage that can be shielded. The empowered vitae instantly heals the subject if they are wounded: injuries briefly appear only to vanish as they are countered by the hauberk.
  Mechanically: one vitae counters 2 bashing (battering, bruising) damage or 1 lethal (cutting) damage; five vitae are needed to counter 1 point of aggravated (crippling) damage. Each success activating the ritual allows for empowering one point of vitae.
  Offering: the vitae used in the ritual, which turns to ash only after it has been used to absorb damage
  Vampire the Requiem - Covenant: Lancea Sanctum p. 194

Level 2 Rituals

• Ascendant Radiance: The miracle worker takes on an exaggerated, unearthly appearance that is awe-inspiring to behold. She glows with heavenly light — or (if her intentions are less pure) hellish radiance. Regardless, she will be noticed, and remembered.
  Mechanically: add dots in Theban Sorcery Gnostic Miracles to the miracle worker's Presence. (For Iris, this gives her an effective Presence of 8. Given that the standard maximum the most amazing compelling person in the world could have is 5, this is pretty significant.) The miracle worker suffers a -3 penalty to social actions requiring subtlety, and to stealth.
  Offering: a mask
  Vampire the Requiem - Covenant: Lancea Sanctum p. 197, "Damned Radiance"


• Bird of Sin: Summons forth a phantasmal bird of prey (typically an owl) that is a manifestation of the target's sins (meaning each bird of sin is unique to the target the miracle is invoked against), and is tangible only to them. The bird assaults the target with its beak and claws; the target will find that the strength of its attacks are directly proportional to their own sins, and that mundane defenses are useless against it.
  Mechanically: The summoned bird has a dice pool of 10-[the target's Morality or Humanity]. (Morality and Humanity are, respectively, the mortal and vampire moral scales, and rank from 0-10. An average person has a score of 7; someone who's had to do some bad things to get by might have more like 5. Someone with a completely inhuman morality could only have 0.) The bird's attacks deal only bashing (battering/bruising) damage, but the target has no Defense against them. However, the target can attempt to will the bird out of existence with a successful Resolve + Composure roll, penalized by Iris's dots in Theban Gnostic Miracles (which is to say, with a -5 penalty). Otherwise, the bird will continue to attack for a number of rounds per successes scored to activate the miracle (minimum 2).
  Offering: a feather at least four inches long
  Vampire the Requiem - Covenant: Lancea Sanctum p. 196


• Curse of Babel: This miracle is practiced by the Sept more or less exclusively as a counter to the vampiric discipline, Dominate, which allows vampires to give commands that must be obeyed. The Curse of Babel leaves the target speaking in tongues for hours.
  Mechanically: lasts for one hour per success scored to activate the miracle (minimum 2) or until the next sunrise — whichever happens first. The roll to activate the miracle is penalized by the target's Resolve, and the target must be in earshot when it is activated.
  Offering: an animal or person's tongue
  Vampire: The Requiem Core Rulebook p. 146


• Liar's Truth: The miracle worker "blesses" the subject so that their truths and falsehoods are made obvious. For the duration of the scene, if the target of the miracle speaks any conscious lies (lies of omission or unknowing falsehoods don't count), white moths flood from their mouth.
  Mechanically: Invoking the miracle is a contested action of the caster's Intelligence + Academics + Gnostic Miracles vs. the subject's Resolve + [supernatural power stat]. (Yes, this does mean non-magical/supernatural people get +0.)
  Offering: a moth or butterfly, whole and uncrushed
  Vampire: The Requiem Core Rulebook p. 147, "Liar's Plague"


• Resistance of Discipline: The miracle worker grants herself, or someone who can hear her voice, a renewed (and potentially empowered) attempt to resist any power currently affecting her/the subject of the miracle, whether or not that power was resisted in the first place. In this way, the Sept and their allies were better able to combat the unnatural mental influence of other vampires.
  Mechanically: The target of the ritual re-rolls whatever pool they used to resist the power used on them (usually Resolve or Composure + [supernatural power stat]), and may spend willpower to improve the roll whether or not they did so before. If, when the sorcerer performed the miracle, she gained successes beyond the threshold to activate the ritual (beyond +2), those become bonus dice to the (Resolve/Composure + [power stat]) roll. (For example, 3 successes would grant +1 dice.)
  Offering: a holy symbol (e.g. a rosary, Star of David necklace, etc.)
  Vampire the Requiem - Covenant: Lancea Sanctum p. 197 (house ruled)

Level 3 Rituals

• Warrior's Blessing: By kissing the blade (or other deadly surface) of a weapon, the miracle worker temporarily blesses and strengthens it, empowering it with her own Gnosis. Only the part of a weapon that actually damages may be thus blessed—a single arrow or bullet, but not a bow or gun, for example; for this reason, the ritual is used almost exclusively on melee weaponry. With a prayer, the weapon's blessing may be invoked by its wielder.
  Mechanically: The weapon's damage rating increases by Iris's dots in Gnostic Miracles (so, +5, which is significant). The blessing applies for a number of attacks equal to the successes Iris scored on the activation roll (minimum 3). The weapon's user says some small prayer each time they want to spend one of the blessing's charges. Blessed attacks not used before the sun rises are wasted.
  Offering: the weapon to be blessed, which is degraded rather than destroyed after the miracle's effects wear off
  Vampire the Requiem - Covenant: Lancea Sanctum p. 198, "Legionnaire's Blessing"

Level 4 Rituals

• Spear of Faith: "Chain lightning" — Any enemies who the miracle worker can see directly may be targeted by this power. Iris chooses her targets (up to 5), and assaults them with her will alone, causing wounds to erupt from them as if pierced by a spear, with the closest target being most severely wounded, and the furthest the least. Armor and other forms of defense are useless against the supernatural attacks.
  Mechanically: The victim closest to the miracle worker suffers Lethal damage equal to successes scored on the activation roll (minimum 4). The next closest suffers one point less of damage, and so on until every victim has been affected or no more damage remains. The roll to activate the miracle is penalized by the highest Stamina of the selected victims.
  Offering: a metal pendant or idol in the shape of a crucifix or spear
  Vampire the Requiem - Covenant: Lancea Sanctum p. 201

Level 5 Rituals

• Fires of Vengeance: This dark miracle is, in the Sept, reserved for those who truly have nothing left to lose. With a declaration of a crime to be punished — e.g. "Murderers!" — the miracle worker summons phantasmal white fire that sears any within the miracle worker's line of sight who have committed that crime with a strength proportional to the severity of their own corruption, and continues to burn for several minutes, as long as the miracle worker stands still to channel the flames — enough to severely injure (and potentially kill) any target who cannot escape the miracle worker's sight. However, the ritual carries a heavy cost, burning away some of the miracle worker's own goodness.
  Mechanically: The flames cause one point of Lethal damage (even to vampires; it's not Aggravated because it's supernatural fire rather than true fire) per success scored with a dice pool equal to [10-target's Morality/Humanity], resisted by a Resolve + Stamina roll from the target; if they get more successes than the damage that would have been done, they suffer no damage that turn; otherwise, they suffer the full damage. They roll again each new turn. The Fires of Vengeance continue to burn for one turn per success scored on the activation roll (minimum 5). However, if the miracle worker loses sight of any victim, the effect ends for that victim alone. If she moves, the effect ends entirely.
  Offering: The vampire’s Humanity (that is, their own goodness/morality/connection to humanity). To perform this terrible miracle, the vampire gives her body up to her inner Beast and cannot deny the loss of her self in the process. The miracle worker’s Humanity automatically drops by one. A derangement roll may still be called for (that is: becoming a worse person has the potential to do long-term damage to the user's mental health in the form of developing some form of neurosis) if the use of the power does not align with the miracle worker's Virtue.
  Vampire the Requiem - Covenant: Lancea Sanctum pp. 202-3


• Font of Virtue: This miracle purifies and uplifts, spreads blessing and peace, and turns ash to beauty. By standing in the place she wishes to bless and making her offering, the miracle worker heals and restores the environment around her while simultaneously infusing it with an aura of virtue. A building or area blessed with this ritual is rejuvenated, returning any functions that may have been lost to age and decay. More importantly, the space resonates with a Virtue: anyone who uses the space finds that, while they are there, that virtue becomes their own. If they visit long enough, the place's virtue may remain with them for a time even after they leave.
  The change to the space is permanent until or unless the space is affected by some other, more potent magic or is otherwise spiritually corrupted. (Renovating the area only may or may not remove the blessing, while destroying it completely will completely end the miracle's power.)
  Mechanically: In nWoD, the Virtues are: Charity, Faith, Fortitude, Hope, Justice, Prudence, Temperance. The roll to activate the power penalized by every dot the place would have in the Haven Size merit if it were a haven (up to 5). For every amount of time (up to the person running the game; suggested length = [10 - the character's Morality/Humanity] x 10 minutes for first-time visitors), the character makes a reflexive Resolve + Composure roll against a dice pool equal to the successes on the miracle's activation roll (minimum 5 dice). On a failure, the Virtue of the place temporarily becomes the character's own, and remains with them until they act upon it.
  If the site is renovated, roll a pool equal to successes scored on the miracle's activation roll (minimum 5); if a success is produced, the Virtue remains.
  Offering: a ceremonial cross or other religious icon, of a proportional size to the location to be blessed (small areas require only small charm-sized items; large areas might require a cross as tall as a person)
