From my understanding, a charm imbues an energy or trait into an object that didn't have it before. The same is true for enchantment.
A curse is an elemental spell geared to corrupt the energy of someone else to cause harm from the inside out.
A hex is sending a nasty spirit of some kind to ruin, corrupt or destroy someone.
A boon is an elemental magick that brings about a positive result, like luck, or drawing in companionship.
A ward is some kind of protection spell, types of wards vary.
A beacon is the opposite of a ward. Instead of keeping you safe from a bad thing, it draws in a good one.
Invocation is pulling a spirit of some kind or a powerful energy into you. Evocation is summoning a spirit or energy outside yourself. Think of the in like internal and the E like external. Conjuration is bringing forth energy or spirits. Both invocation and evocation count as such.
Manifestation is when the effect of a spell or spirit effects the physical world.
Blood magick is considered dangerous magick because it uses life force and blood as a catalyst and energy source for a spell. This is by nature very dangerous as using too much will drain or kill you.
Elemental magick is calling upon the elemental energies or elemental spirits, converting the energy and commanding it, then often releasing it to achieve the desired results.
Priest or priestess magick involves the invoking of higher spirits aka dieties or gods, and kindly asking for help. This is most commonly done with your matron and or patron goddess and or god.
Shamanic magick is often calling upon animal, plant, or ancestral spirits for assistance, as well as entering the spirit world via meditiation. The spirit world interacts with the physical one.
Mediumship is very close to shamanism except instead of animal spirits, they tend to work with human spirits and ancestral spirits.(for some stupid reason I never realized how similar a medium was to a shaman)
Casting a circle is the process of purifying a space into a sacred space, then casting magick. while it's often elemental, it is not always.
These are a few of the terms as I know and understand them.
I'm a spiteful, hateful, venomous creature, a pupil with no scruples who's no better then my teacher. Also not actually a raven.
