Istarelle is found on a corpse atop one of the buildings suspended above Leechmonger's arena in 5-1. To reach it, the player must climb a ladder found outside the building where the Filthy Woman initially appears; however, the ladder only appears in Pure White World Tendency. It is guarded by several Depraved Ones as well as one giant Depraved One.
Like the Rune Sword, most of this weapon's damage comes from magic damage, which scales with Faith; this makes it the only spear that can scale with Faith by default. Like the Club and the Great Club, this weapon is wooden and cannot be coated in Turpentine or Black Turpentine.
