• Interrupt Kobyss Witherer's Abyssal Surge cast.
• Beware of Kobyss Bonechewer's Scavenge buff, any spare interrupts should go for Throw Junk cast.
• Watch out for the amount of Slippery Syphoners you pull, although they have lower health, they will Crunch you and cast Corrosive Bile.
• Interrupt Leviathan Manipulator's Necrotic Bolt and avoid their Defiling Breath frontal. If you engage with Kobyss Necromancer they have exactly the same abilities as the Leviathan Manipulator.
• Beware of Kobyss Trickster and its uninterruptable Illusive Step cast, he will create an illusion that will continue to attack you (Pale Illusion) and hit you with Cleave frontal cone ability.
• Kobyss Spearfisher are the worst mob in this area due to their Spearfish cast, which grips you in melee and immediately hits you with Slashing Rend.

Destroy 7 Leviathan Balts.

• Interrupt Abyssal Surge cast.
• Focus and kill any Slamming Tentacles arround the boss, else he will gain an immunity to any damage source. It is best to try your best and cleave them with Leviathan Caller.
