Note: These are general/basic explanations of different classes of magick/witchcraft. Practitioners can fall into multiple or none of these categories. Ultimately, only an individual can choose their labels.
Green: Utilizing greenery/plants/herbs/flowers in herbal/nature magick, such as creating blends of different plants or primarily using herbs in spellwork. May keep a garden and take great pride in their workings/connection to the earth and nature.
Hedge/Shamanic: A type of magick that's more oriented towards spirit work, Otherworld and astral travel, dream work, spiritual power and healing. May work with psychedelic/psychotropic/toxic plants and fungi as spiritual tools (ie: flying ointments/teas made from amanita muscaria or datura)
Sea: A type of magick derived from materials/abstract ideas involving the ocean world. Sea magick is worked using various items from as well as one's own connection to the sea and its creatures.
Storm: Magick that is worked by combining one's own energy with the energy of the weather, most commonly storms. Storm witches may have practices such as collecting storm water or snow, "whistling up" or manipulating winds, or performing rituals during severe weather.
Hearth/Kitchen: Magick performed through kitchen craft and/or mundane tasks/crafts around the home or for loved ones. Typically worked daily through food, herbal mixtures, crafting, decorating, and hobbies. May also work with the Fae/elements/nature.
Tea: Those who drink tea, make their own tea mixtures, or enjoy blending herbal remedies and often use reading tea leaves as their form of divination.
Urban: For those who live in or prefer an urban setting/lifestyle. Magick that is worked in densely populated areas and big cities, without some of the seemingly "traditional" aspects of witchcraft.
Tech: Magick that is skillfully worked through technology. A tech witch might cast spells/do divinatory readings on the internet, use magick based apps/programs, or keep a digital grimoire/library.
Elemental: Magick that is worked by honoring/acknowledging all 4/5 elements (Fire, Air, Water, Earth, and/or Spirit). Elementalists may dedicate part of their alter to each element and call upon them during rituals/spells. Conversely, they may choose to focus on only one element changing the designation to either fire, air, water or earth witchcraft.
Fae/Faerie: The magick of those who work and commune with the Fae. Faerie witches may do rituals/spells around the Fae, ask favors of them, have regular communication sessions, and leave them offerings. The Fae are very unpredictable and strong but, with time and respect, they share their magick with special individuals.
Infernal: A system of spirit work/magick that revolves around Infernal spirits/entities, such as demons, djinn, or other spirits of a chaotic alignment. This practice requires a surprising amount of shadow work and dismantling of oppressive religious systems. They may summon demons, perform rituals/spells with them, make deals, or take them up as magickal familiars.
Necromancy: The practice of seeking the assistance of, summoning, communication, and diving through the dead. Practitioners may frequent cemetaries/burial grounds/haunted locations and perform magick and spiritual/divinatory readings there. Often employ the use of pendulums, dowsing rods, talking boards, black mirrors, grave dirt, and bones.
Draconian: Draconian magick is a practice that involves engaging with dragons as powerful forces and allies in spiritual practice. It can include rituals, symbolism, and techniques to connect with dragons, and may be used for empowerment, healing, and spiritual growth.
Chaos: A type of magick utilizing new, non-traditional, and unorthodox methods. It is a highly individualistic practice that draws from many magickal disciplines (eclecticism).
Blood/Sanguine: A very potent class of magick that includes the use of one's own blood or that of another in powerful rituals/spells.
Sigil/Art: The use of sigils, symbols, glyphs, runes, or artwork infused with will and intention. This practice is vast, versatile, and diverse with each practioner producing truly unique results.
Lunar: Lunar magick is the practice of performing rituals during the different phases of the Moon to bring about physical or psychological change. They may honor/worship the Moon, do moonlight rituals, or make moon waters. Conversely, one could work with the Sun in much the same fashion.
Cosmic/Celestial: Magick that incorporates the stars and planets. Astrology is a dominant force in their lives and witchcraft and they consider the placement of celestial bodies before doing a working.
Crystal: Incorporation of crystals/stones in one's magickal practice. May make crystal grids, include them in their spells, use them in energy work, meditation, or for Reiki healing.
Glamour: Glamour magick is an enchantment type that adjusts or changes your outward appearance, or people's perception of your outward appearance and can include the enchanting of jewelry, clothing, and even makeup for magickal purposes.
Shadow: Magick with a focus on the elements of darkness and shadow. May practice umbrakinesis (shadow manipulation), magickal subterfuge and illusion, and feel at peace, and even practice, in pitch black darkness
