Black Knife Assassin (Sage's Cave) Altus Plateau Boss

Description

Black Knife Assassins are bosses in Elden Ring. They are hostile humans who await in catacombs for their next victim. This particular assassin waits in the Sage’s Cave dungeon. She uses the Concealing Veil which’ll make her invisible during the boss fight which can be easily dispelled by using the Sentry’s Torch. If you don’t have access to the torch, you can see where the assassin is by looking closely at the deformations in the water or dust clouds that appear on the ground when she moves on land. Furthermore, she’ll try to backstab you which’ll deal significant damage so make sure you don’t make it easy for her. You’ll receive the Concealing Veil for defeating her.
