Múspellflame (ムスペルの炎, lit. Flame of Múspell) is a Sacred Seal skill introduced in Fire Emblem Heroes. It is the personal skill of Surtr, but while similar to Embla's Ward in terms of it granted invincibility, it is not temporary. Múspellflame can only be dispelled through the completion of the Rite of Frost.
