Hört Glut Rachegötter

is the Noble Phantasm of Kriemhild.Fate/Grand Order - Kriemhild Profile - Translated by Lapithae 
It is the embodiment of an anecdote about an attempt to dispose of a group of warriors, including her own brother and Hagen, by setting them ablaze in revenge. With Hagen’s advice, the warriors suffered only minor casualties, so with proper advice and countermeasures, the damage could be reduced. In that sense, it’s not the strongest of trump cards.
However, the true value of the Noble Phantasm is in how the warrior’s prideful ideal of “If I die, I’ll die on the battlefield” is worthless to Kriemhild. Hence, if it’s used as part of a scheme or a deception, the power will be increased.
This ability is not used in FGO.
