Instance Description
Light Novel Anime Manga
Volume 3, Chapter 4 Episode 18 Leafa used this spell in the sky of the Ancient Forest to finish off the last Evil Glancer that tried to retreat with around 20% of its HP left after all the other lizards in the area were wiped out by Kirito.
Volume 4, Chapter 8 Episode 23 Recon uses this spell to attract the attention of Guardian Knights away from Leafa during the Grand Quest.


  • Although Recon's version of the spell in episode 23 looks different from Leafa's version, it is the same spell. Reki claims that there is a skill that strengthens spells, which is why they appear different.[9]
