Cleric 101 Light Domain Dungeons & Dragons

Warding Flare Also at 1st level, you can interpose divine light between yourself and an attacking enemy. When you are attacked by a creature within 30 feet of you that you can see, you can use your reaction to impose disadvantage on the attack roll, causing light to flare before the attacker before it hits or misses.. The impression was that in using the reaction with warding flare, that is somehow separates the spell ability from the original stack of advantage/disadvantage.

Is the disadvantage imposed by warding flare active on the "whole" multi attack, or just on one component of it? i.e. just the bite, not the bite and claw. Thanks in advance!.
