Occultism

Warlock | Blood | Necro | Soul

Also known as Shadow Arts or simply shadows, Occultism heavily involves access to the elemental plane of darkness, much like the elemental planes tapped by portal witches, but access to shadow isn't something that comes naturally to portal mages. The plane itself seems to have an active will and conscious of its own... watching you. Other elemental planes are theorized to be sapient in the same way but less aware, or their attentions are drawn elsewhere. This Shadowmind appears to act as a mediator for certain ritual practices, control of shadow... and can become possessive of its practitioners. Any sacrifices can actually be resurrected, if you are able through various means. Any given ritual can also share its benefit with other participants in the ritual, the primary ritual leader (The one with the Occultism being used) can selectivley pick and choose.

Rank 1

Process: Rank 1 rituals require privacy, and either extreme of nudity or having no skin showing. No more light than a single candle. Ritual takes 2 minutes.
Rituals: Luck. Something mildly lucky will happen within 24hr, stacks. Sleep. Within 2hr, fall asleep easier, for a deeper sleep. Desire. Get a 6th sense for people you have a shot with, they'll feel a mild magnetism with you, for 24hr. Spider. Climbing becomes extraordinarily easy, as though your own body weighed nothing to you for 24hr.

Rank 2

Process: Rank 2 rituals are as rank 1, but include any animal sacrifice (Mouse or chicken for example) or a willing partner to perform the ritual with you.
Rituals: Fate. Hear whispers of vague information with insight into your / another's future at the time (Changes with actions / new intentions), for 5 minutes. Silence. Create no non-vocal sounds for 24hr. Muse. Hear whispers giving creative insight to a problem at hand, and a boost in motivation to follow through, for 1 week.

Rank 3

Process: Rank 3 rituals require the sacrifice of a goat, sheep, dog (Medium to large), or a ... well, ah... tantric interaction with a partner(s) in the ritual.
Rituals: Darkness. Imbue an object with darkness, for a 60ft radius area that light can't penetrate (Molding to conform to walls, like a light source) Darkvision. Ritual participants can see without light, in greyscale, for 1 month. Fortune. Business affairs are an average of roughly 50% more favorable to you, 6th sense for market fluctuations and potential; Get an impression bitcoin will dip if you wait an hour before buying, etc; Lasts for 1 month.

Rank 4

Process: Rank 4 rituals require the sacrifice of two large animals (Horse, cow, bison,ect), or 1 human, or a tantric exchange with at least 3 partners, with 2+ other witnesses.
Rituals: Shadow Passage. Open a rift to the shadowrealm, a decayed mirror of the real world with no light what so ever. Every living thing has a horrifying counterpart in the same general area as reality. They all stare. Once you've entered, this ritual stains you for good and you'll see it in any reflection that is under a shadow, which you can use to enter or exit like an open window, even dragging others with you, who can't escape the same way unless also a recipient of Shadow Passage. Revenant. You can ritually separate a person from their shadow, and it seems to have a life of its own, capable of moving independent of light sources, even in 3D space as a humanoid absence of light. It can physically harm creatures or objects as though it had twice your physical attributes, with claw-like fingers. It can be harmed by silver or contact with light emitting sources. This shadow can hide in any other shadow, or merge with a creature, overlaying them like an aura, to influence their personality and the shadow claws providing a weapon.

Rank 5

Process: Rank 5 rituals require the sacrifice of a willing human virgin dedicated to the purpose, immediately followed by a tantric exchange with the sacrifice, and 6+ witnesses. Many Hespatian families have such candidates available, and you might find some in the Watchers though in different context and perspectives with more of a martyr undertone.
Rituals: Ritual of Shadowbinding. Ride the departed soul directly through the veil of death to physically enter the spirit world of Limbo, the place of reaping where unclaimed souls go to rest until claimed. Here you can find gates to every other afterlife to exist, known and untold, the ways guarded in their own various ways, some hidden, some domineering. The Shadow grants you a harvesters scythe- And a whisper; Reap. For every soul you harvest the scythe becomes darker until it's as a definitionless 2D void. When you return, the scythe merges with you, leaving you shadowed or void-black. For every soul up to 666, recieve a 2% boost to stamina, speed, strength, magic area of effect and range. You can have your shadow grab the scythe from you and implant it in someone else, or hold it itself as a way to toggle the effect off. Can be broken up into shards or bundles of souls to give a portion of the percentage buff to multiple entitites at once. Lose 3 souls per day, the souls leaking free to become lost wandering souls in the world somewhere. Toggling it off prevents souls from leaking. While you have the scythe / the buff is active on you or another, any kill traps the soul of victims to replenish up to a total of 666 once again (divided as appropriate, if split).

⭐ Dominion

Magician | Nature | Earth | Mind

Dominion is the magic of creating bubbles of artificial reality inserted over the material reality. The true reality beneath remains unchanged as you control the nature of the artificial bubble of your own influence; Your Domain. The domain is invisible to the outside as you see the true reality, and non-magic humans aren't affected, they'd walk through into the true reality unaware of the bubble's existence, likewise mortals within the area of the bubble when it is created simply disappear, not a part of the artificial, though copies of plantlife and inorganic things still carry over. Bubbles can conform to the area of a given room, or ignore it to fill its full diameter. Bubbles are immobile and you can only have 1 bubble active at a time, the first blinking out as the first flickers into existence, but it can be maintained indefinitely. Witches can see a translucent outline of a bubble but can't choose to enter the material instead of the artificial reality, other than rift mages and other teleportation tricks directly bypassing the bubble to enter the material version of that space. Dominion is unaffected by Warding, though warded individuals aren't directly affected by any imposed extremes that differ from the material, such as false gravity.
It takes 10 minutes of focused meditation to establish a bubble, which is about as exhausting as running a lap around a track (-50% per rank of size less than your max rank). You could let mortals into a Domain the same way a witch could access the material under a bubble; Portals.

Rank 0
Almost every witch with basic practice is able to learn to create "Combat Zones" easily with a snap, clap, or knock to instantly form a 120 meter radius sphere of a basic bubble that provides no other effects other than being a basic bubble, useful to separate out the mundane providing a safe area to engage with supernatural threats or combat another witch, or other entity. Can also be used to escape most normal mortals to appear to disappear before their eyes, or just have a private chat with another witch.

This does not imply the witch has any knowlege about the Dominion school of magic, as Dominion is just an evolution built on top of the ability to create combat zones.

Rank 1

To begin with, you can create a 15ft diameter sphere. Within the sphere you can change the temperature to within 30 degrees of room temperature and generate enough oxygen to sustain one person indefinitely, so long as the bubble holds. Useful for separating a room to hide a set up from mortals as well as some nice AC.

Rank 2

Achieving rank 2, you can create a 60ft diameter sphere. Within the sphere you can dim or brighten light levels by +200% or -50%, degrees by 40 from room temp, and generate oxygen to sustain 12 people indefinitely, so long as the bubble holds. Time can be dilated by 10%, making things within the bubble appear 10% faster or slower to the outside (and vice versa). It's now useful for hiding small buildings or equipment, or simply making a room more productive by speeding it up by 10% relative to the outside.

Rank 3

At this rank you can create a 240ft diameter sphere that effects light levels by 400% or -75%, degrees by 50 from room temp, oxygen for 144 people, and time by 20%. Now good for covering most standard buildings or small fields, and you can now manipulate earth and water within your domain as though you had telekinesis influencing mass up to 1 ton at a time, and your bubble can choose whether or not water exists within it or can flow through it, meaning a bubble in a river could produce a dry space.

Rank 4

With the 4th rank of Dominion, you create bubbles up to 960ft in diameter, within which you have complete control of light levels, degrees by 60 from room temp, infinite oxygen at standard atmospheric levels, or no oxygen at all, time by 33%, and earth/water telekinesis by up to 5 tons. On bubble generation you can choose to include terrain or buildings within the bubble or not, allowing you to have a clear flat space for example, or a sloped crater with no earth within the bubble. You can create any earthen terrain, stone, mineral, metals, or water as you wish within your TK limit, in the shape you desire within your skill level with your artistic ability. This is false matter that disappears with the bubble, or if removed from the bubble.

Rank 5

At rank 5, your bubbles can be up to 15,000ft in diameter (4.5km / 2.8mi), in which rank 4 control applies with degrees by up to 100 degrees from room temp, time by 50%, tons by 20. You also learn to channel Dominion into the distillation of a crystal shard that can maintain its own bubble independent of your limit. If the crystal shatters, the bubble collapses. A shard can be created after a bubble has already been established to anchor it, and you can have multiple shards stabilizing one bubble, which can extend its area. While within your domain, any magic you use has a range of anywhere within your domain, and your magic costs nothing to use except your natural stamina and fatigue.
