The three main arenas in Elden Ring are now unlocked after the latest Colosseum update. Players can now engage in PvP fights in these Colosseums. While that sounds fun, you don’t want to head into these battles without the right weapons and even Talismans. The latter is an item that can be used to increase damage, improve defense or even increase carrying capacity. We’re going to touch down on one such Talisman known as the Assassin’s Cerulean Dagger in Elden Ring colossal. It’s a very useful item for late-game strategies. If you’re struggling to get it, we’ll show you where to find the Assassin’s Cerulean Dagger in Elden Ring.

How to Find the Assassin’s Cerulean Dagger in Elden Ring

The Assassin’s Cerulean Dagger in Elden Ring restores 15 Focus Points (FP) per critical hit. If you want to get it, you will have to defeat the Black Knife Assassin boss found in Black Knife Catacombs near Liurnia of the Lakes.

To reach here, you will have to travel north from the Church of Vows which is situated near the Eastern Liurnia Lake shore. The location is marked on the above image. Once you traverse north, you will come across a headless Mausoleum Knight standing in front of the entrance to the Black Knife Catacombs. This is where you need to be, we have marked the exact location in the Elden Ring map below.

It’s not necessary to fight this guard so simply make your way inside. However, you will now have to make your way past the hostile skeletons in the Dungeon. Once that’s done, at the end of the passage you will find a wall which is not actually real but only an illusory wall. Strike the wall to reveal the hidden boss room. Once you enter the room, you will be greeted by a Black Knife Assassin. He will charge at you and start the fight. Keep in mind, he is very strong and agile so make sure you’re well prepared. Once you defeat it, you will be rewarded with the Assassin’s Cerulean Dagger in Elden Ring colossal.
