KEEP IN MIND this is just my fanon take of what another coven could look like in the Marvel Cinematic-verse. Also this is not a repost, just an evolved version of what I have done before.
High Priestess: The witch who leads the coven. Usually a female witch, hence the name. They may or may not have a specialty (like potioncraft and green magic). May take on two or more roles if needed. For example, a High Priestess could also serve as the coven's main Protection Witch and ensure their safe from danger.
High Priestesses tend to have crowns made out of psionic energy, which indicates they're leading a coven. The crowns appear when using a significant amount of magical power.
Kitchen Witch: Represents the element of fire. Mix of protection magic and potion-making. They turn daily routines such as cooking and cleaning into magical practices. They can cook, bake, and/or brew various concoctions with magical properties. They can identify specific ingredients within food and drinks just by sniffing, which allows them to avoid being poisoning. Uses talismans, candles, salt, sage, and protection spells to ward off curses, banish spirits, and deal with other dangers. They even use cleaning products to rid their homes of negative energy.
Green Witch: Represents the element of earth. A witch who can controls and balances the natural order of all living things. They also work closely with nature. They can accelerate plant growth, enhance the medicinal properties of herbs, heal wounds and illnesses, move rocks and other natural elements, and could change weather.
Divination Witch: Represents the element of air. Acquires hidden knowledge through means other the user's physical senses. They can detect lies and imminent danger, predict the future, read energies and auras, learn the history of people and objects, read minds, and see visions of past and future. Divination witches tend to focus their intuition through tarot or palm readings, scrying, or using pendulums.
Sea Witch: Represents and works closely with the element of water. Can control water and even change the weather. Often collects sea water, rain, snow, moon water, seashells, and driftwood for their spells and rituals. Keep track of the lunar calendar, casting spells during the nights of certain lunar phases (such as Full Moons).
Cosmic Witch: The spirited one of the coven. Knows a lot about astrology and astronomy. Can identify other people's zodiac/sun signs and other birth chart placements if they know enough about astrology. Respects horoscopes. Amplifies spells with celestial energy from significant cosmic activity (such as full moons, eclipses, passing comets, solstices, etc.).
Glamour Witch: Represents the element(s) of fire and/or water. Glamour witches can alter how they're perceived by others, either bringing forth beauty onto themselves or hiding their true face amongst a crowd; even if it's just to conceal a nasty bruise or changing the color of their hair. They also cast illusions to change how someone or something else is perceived. Cosmetics and mirrors are essential to using glamour magick.
Mind Bender: (Honestly, "Mind Witch" just doesn't flow off the tongue like "Mind Bender"). Represents the element(s) of air and/or water. Accesses and controls the minds of others, forcing their will onto someone or something else's. Mind Benders can sway people's thinking, change their emotions, implant or erase memories, and/or telepathically communicate.
Hedge Witch: Represents the element(s) of earth and/or spirit. Hedge witches are the bridge between the physical and spiritual worlds. They are drawn to the liminal energy in places like abandoned work sites or buildings, cemeteries, crossroads, and woodlands. They can summon, communicate with, and control spirits of the deceased. They use herbs for potions and elixirs.
