This part of the Elden Ring Guide is dedicated to the fight against the Black Knife Assassin.
Here you will find tips and a video that will help you defeat him as well as information about the rewards you can get.
Rewards: Assassin’s Crimson Dagger
Location: Deathtouched Catacombs (West Limgrave)
For magic users, this fight will be surprisingly easy. As always, start by summoning spirits and then cast your spells from behind the Boss’s back while he is busy with your henchmen. Sometimes the Assassin will chain a series of dodges, making your spells completely useless. In this situation, run into his back and try to land a good combo or a heavy attack to knock him down.
In hand-to-hand combat, summon henchmen as well and then continuously move to the back of the boss. Then use heavy attacks to knock him down before dealing lethal attacks.
