La Grondement Du Haine

is the Noble Phantasm of Jeanne d'Arc (Alter). "Roar of Hatred."
The cursed flag possessed by the Jeanne who descended as the Dragon Witch. It stops the enemy’s attack in the same way as Jeanne d'Arc’s Noble Phantasm, but this Noble Phantasm also swells up that attack, before it reflects it back.
Fate/Grand Order material III - Jeanne d'Arc (Alter), p.302-313, translated by Kinalvin at Reddit. Also, its power will increase even more if her allies and the likes die. Then, whether it is a slashing attack, a striking attack, or on top of that, a hit by means of a curse, all of it will in the same way be converted into her physical attack power when they are halted by the Noble Phantasm.
The flag can release flames with performance resembling a first-rate Dragon’s breath. Under the name of an avenger, Jeanne Alter kindles the flames and transforms the grudges from herself and the surroundings into magical energy, burning the opponents' injustice, corruption and self-righteousness up to the marrow of their bones to ashes.
 Furthermore, the stake was stuck into her image. Personally for her, “I was attached to… uh, something jagged… and made of steel, and a harsh impression of it remains with me!”, and this impression allows her to create these stakes in her image for her own use.
