Kraken - OSRS Wiki

The Kraken is a stronger and larger version of the cave kraken. It requires level 87 Slayer to kill and cannot be boosted. Located at the Kraken Cove, it can only be attacked if the player has cave krakens as a Slayer task, which also requires level 50 Magic. Alongside its non-boss variants, it is the only monster that drops the trident of the seas and Kraken tentacle.
