The first variation of the attack emitted a large force of energy which originated from the palm of Nephrite’s hand and was used to knock Sailor Moon to the ground and save the life of Naru Osaka by splitting the mask of youma Yasha into two. The second variation of the attack was formed as he clasped his hands together and called upon the stars to give him power, then fired blasts of power at Sailor Moon to again incapacitate her. The last variation of the attack saw him cross his arms to form multiple balls of light, which orbited in circles similar to a planet's rotation. Upon gaining enough energy would he fire the projectiles at her.
Both the second and third attacks missed Sailor Moon although it is obvious that it can do quite a bit of physical damage to whatever it hit. Nephrite uses this attack while disguised as Masato Sanjouin, but he can probably perform this attack in his true form. The name of the attack seems to be a reference to the astrological means Nephrite uses to perform intonation with the stars and its constellation. In the anime, Nephrite would yell "Starlight Attack” before he would attack his target.
