The Great Serpent is a unique boss encounter in Sekiro: Shadows Die Twice, primarily focusing on environmental interaction and timing rather than traditional sword combat. This colossal serpent inhabits the Sunken Valley and presents a significant threat due to its immense size and its ability to instantly kill You with its bite. The encounter is less about depleting its health bar through direct attacks and more about navigating the treacherous terrain while avoiding its devastating lunges and bites. Understanding the serpent's attack patterns and the safe zones within the arena is paramount to survival. The Sunken Valley is a perilous environment, and the serpent's presence amplifies this danger.
This boss fight serves as a stark reminder of the world's dangers beyond human adversaries. The Great Serpent's attacks are powerful and can cover a vast area. Players must learn to read its movements, which are often telegraphed by its head movements and the ground shaking. The primary objective is to reach the end of the serpent's territory without succumbing to its attacks. There are limited opportunities for direct damage, and the focus should be on evasion and strategic movement. The terrain itself plays a crucial role, offering some limited protection but also presenting its own hazards. Successfully navigating this encounter requires a shift in mindset from aggressive combat to careful observation and precise movement.
Navigating the Sunken Valley
As you enter the Sunken Valley, you will immediately encounter the Great Serpent. Your primary goal is to move forward through its territory. The serpent will often lie in wait or patrol the area. When it lunges, you must quickly dodge or find cover behind the rock formations. There are specific points where the serpent will attempt to bite. These are often preceded by it rearing its head. When this happens, you need to sprint in the opposite direction of its lunge or find a safe spot. The terrain offers some small ledges and alcoves that can provide temporary respite from its attacks.
Avoiding the Serpent's Bite
The Great Serpent's bite is an instant kill. It has several variations: a forward lunge, a sweeping bite across the ground, and a grab. When it rears its head and prepares to bite forward, sprint to the side or backward. If it begins to slither across the ground, you will need to jump over it. There are moments when the serpent will coil up, creating an opportunity to get closer. However, be extremely cautious. The most effective strategy is to keep moving and use the environment to your advantage. Do not attempt to attack the serpent directly; focus solely on evasion and reaching the end of the area.
Reaching the End of the Encounter
As you progress, you will eventually reach a point where you can climb up a ledge. The Great Serpent will often follow. At certain points, you will need to use your grappling hook to traverse gaps. The serpent will attempt to intercept you during these moments. Timing your grapples is crucial. There will be a specific point where you can perform a stealth Deathblow on the serpent. This is achieved by approaching it from behind when it is coiled or distracted. Successfully executing this Deathblow is the primary way to defeat the Great Serpent and clear this section of the Sunken Valley.
