The Whisperer

The player must bring the blackstone fragment to initiate the fight, as parts of the fight will require the player to enter the Shadow Realm; the player will refuse to fight the Whisperer without it.

As the fight takes place in the Lassar Undercity, sanity is present throughout the fight, though it is present throughout the whole fight rather than just the Shadow Realm. When outside the Shadow Realm, the player will slowly restore 1% sanity every 4 ticks; inside, the player will lose 3% sanity along with 3 prayer points. Sanity can be further decreased regardless of which realm the player is in if they are hit by her tentacles or fail to avoid/stop her special attacks. If the sanity bar fully depletes, the player will go insane and will quickly die within 10 ticks; therefore, if this occurs, teleportation is mandatory.
