Metamorphosis refers to an Illusion-element spell in ALfheim Online.


Once the incantation is completed, the spell turns the caster into a monster. The shape of the monster that the player is transformed into depends randomly on the player's combat skills. However, this spell is not popular, as the end result is usually a weak monster with no change in stats, thus it is usually not viable in actual combat.[1]

  1. The anime has used the words "auga brott svalr" in the animation, however, the SAO no Subete guidebook contains a different version of the words. As the guidebook also comes with a translation and was released after the anime, it is considered to be the more up to date version.
