Using strange rites you summon a moon-like sphere above your head, choosing Full Moon, New Moon, or Blood Moon when the spell is cast, which emits an aura in a 60ft. Radius around you and summons 3 Wolf Spirits. Each type of moon has a different effect and summons wolf spirits with different abilities. 

Full Moon - This orb emits bright silver light in a 60ft. Radius. When a creature within this radius makes a Wisdom, Intelligence, or Charisma saving throw, you may use your reaction to grant them a bonus to their roll equal to your spell casting modifier. 

Blood Moon - This orb emits bright red light in a 60ft. Radius. When a creature within this radius makes a Strength, Dexterity, or Constitution saving throw, you may use your reaction to grant them a bonus to their roll equal to your spell casting modifier. 

New Moon - This orb seems to absorb light, turning the area in a 60ft Radius around you into dim light. When an enemy within this radius makes an Ability Check or Attack Roll you may use your Reaction to grant them a penalty to their roll equal to your spell casting modifier.
