Will a start new relation spell backfire if done during a new moon? Since the new moon represent new beginnings I thought it will work but most of the information I get is not to only do reconciliation spell.
I would say it’s a good time, depending on the spell.
I see no problem. New moons are generally not the preferred lunar phase for love spells (full moons are used for this) but it will work anyway.
Good luck and Blessed Be!
