Begin by setting up your skills for your chosen weapon and summon the Spirit of Advocacy just outside the gates to the boss for additional support. When confronting the Viper, be prepared for its various attacks:

  • A three-hit combo starting with two stabs and a spear swing.
  • A two-hit spear-swinging combo from left to right.
  • A large sweep followed by a leap away and up to two spear throws.
  • A four-hit combo with a spinning spear, followed by swipes in both directions.

Mastering the timing of your blocks and executing Perfect Guards will rapidly deplete its stamina. Keep up the pressure with continuous attacks and Brutal Attacks when possible. The Spirit of Advocacy can serve as a useful decoy. At around half health, the Viper will roar and summon an energy tornado; be sure to move away to avoid being pulled in.

After the energy blast, watch for the Viper's leaping slam and its new grab attack, signaled by the flashing spear tip; dodge to the right to avoid it. It also introduces a ranged attack with a vertically spinning spear, followed by jumping attacks. All previous attacks now have increased damage and additional hits, so constant blocking is advisable. A Perfect Guard on the final hit of its five-hit combo will stagger the boss, allowing you to deal significant damage.

Once you've depleted its health, the real challenge begins.

Phase 2

In Phase 2, the Viper taps into Hismar’s power, regaining full health and becoming even more dangerous. It uses its fortified left arm for downward smashes and swipes, and a giant sword for slashes. When it roars, anticipate two wide-ranging arm attacks followed by a Burst Attack; use Counterattack to stun it and create an opening for attack.

At half health, the Viper summons a storm that darkens the arena. During lightning flashes, it will leap towards you to attack multiple times, ending with a charge and an uppercut. Parry or dodge these attacks and use its aggressive behavior to your advantage. Be aware of its new leaping slam and adjust your position accordingly.

Always monitor your stamina to avoid being vulnerable during the Viper's sustained combos. Defeating the boss rewards you with over 10,000 Lacrima, Hismar’s Scale, several Fallen Lord items, and the Hunter’s Ring.

With these strategies, you should be well-equipped to conquer the Viper in *The First Berserker: Khazan*. For more tips and guides, visit The Escapist.
