What is an Empowerment?
Each empowerment enacts upon the individual for a specific change until the change is made. All empowerments are a temporary boost in energy. Be aware, with empowerments dealing with entities, that there is a slight chance you might undergo possession.
What is an Attunement?
Attunements allow and individual to connect to the given energy permanently and can be called upon as one sees fit. Once attuned, you'll be able to use the energy to work on not only yourself, but others as well, Attunements are also an act of devotion towards the entity you are attuning to.
