Elden Ring: How To Defeat The Invisible Black Knife Assassin

screenrant.com:

One of the most challenging lesser Dungeon Bosses that Tarnished will encounter in Elden Ring is the invisible Black Knife Assassin of Sage's Cave in Altus Plateau. The fight will likely begin with the player entering the boss chamber only to freeze in confusion that there's no boss in sight. However, this bewilderment will quickly end when the Black Knife Assassin briefly emerges from the shadows to backstab the Elden Ring player and then vanish back into hiding.

It should be noted that, unlike the «untargetable» spectral enemies of Sellia in Caelid or Kingsrealm Ruins in Liurnia, the Black Knife Assassin of Sage's Cave is invisible yet also invulnerable. In other words, Tarnished can still land strikes on this enemy, although they cannot physically see it. Nevertheless, having this knowledge still does not make the fight any easier. On the contrary, an invisible opponent who can endlessly backstab the player will undoubtedly cause vexation for some and may even force several to give up. Fortunately, the game offers several solutions for defeating the challenging invisible Black Knife Assassin.

Keep in mind that the torch has several stat requirements, but the unique effect will still occur even if those prerequisites are not met.
