The Last Quarter Moon lies in the second week of the waning moon phase. This is the time when the visible moon goes from full to dark again and is associated with the crone aspect of the Goddess. This is the perfect time to do banishing magick and rituals to reduce problems.

Any magick to remove negative people from your life (i.e. people who are bad influences on you, treat you poorly or genuinely make you unhappy despite multiple attempts to repair the relationship)
Magick to smoothly end a relationship or job
