The attack that Draegor had used was a simple punch. He had put quite a bit of force behind this attack but it definitely had no killing intent. Draegor was attacking Alexandriana to mainly teach her a lesson and not to actually harm her.
On the other hand, the attack that the Seven Homebound Fairies had launched was filled with killing intent. They were extremely fond of Elena and after seeing Alexandriana trying to attack her, they had immediately retaliated.
But as Seven Homebound Fairies were still quite new as a supreme rank powerhouse, the strength behind their attack was something that a fellow supreme with more experienced would be able to handle without much trouble.
And as Draegor was still weakened and was also holding back, his punch was also lacking a "punch". So the strongest and most dangerous among the three attacks turned out to be from Golden Elena.
