Code Vein: Abyssal Shore Walkthrough

Jump down and keep moving straight until you reach the end of the area. There you will find a chest with Impaler +3. However, the chest is guarded by two spiky orbs. Defeat them and then leave the location. Go to the ruined boat and then turn right. 

Code Vein walkthrough

Go through deep water and then climb up the hill - you will find the last Rotten Mistle. The Iron Queen lies on the right.  

You need to go upstairs - this path leads to the arena where you will face the Corrupted Executioner (this boss uses water attacks). View splash screen. Grab as many Anti-Slowers as you can - this boss can significantly reduce your movement speed. Defeat the boss and then activate the mistle in the arena.
