Before engaging the Viper, ensure you've set up your skills for your chosen weapon. Summon the Spirit of Advocacy just outside the boss gates to gain an extra ally. When you face the Viper, be alert for its attack patterns:

  • A three-hit combo beginning with two stabs followed by a spear swing.
  • A two-hit spear-swinging combo from left to right.
  • A large sweep followed by a leap away, after which it throws its spear up to two times. Be cautious of the returning weapon.
  • 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 quickly deplete the Viper's stamina. Keep up the pressure with attacks and Brutal Attacks whenever possible. Utilizing the Spirit of Advocacy as a decoy can be immensely beneficial. At about half health, the Viper will roar and summon an energy tornado. Move away quickly to avoid being caught in it.

Post-energy blast, watch out for the Viper's leaping slam. It will now attempt a grab attack, indicated by the flashing spear tip; dodge to the right to avoid it. Additionally, it gains a new ranged attack where it sends the spear spinning vertically, followed by a pair of jumping attacks.

All of its previous attacks will now be more potent and include additional hits, so constant blocking is essential for safety. If you can execute a Perfect Guard on the final hit of its new five-hit combo, it will stagger the boss, giving you an opportunity to deal massive damage.

Once you reduce its health to zero, the real challenge begins.

Phase 2

In Phase 2, the Viper taps into Hismar's power, becoming even more formidable with a restored full health bar. It now uses its fortified left arm for downward smashes and swipes, and a giant sword for slashes. When it roars, brace for two wide-ranging arm attacks followed by a Burst Attack. Use Counterattack to stun it and create a window for your attacks.

Once its health reaches the halfway mark, it will summon a storm that darkens the arena. Each lightning flash signals the Viper's leap towards you. It will repeat this several times, ending with a charge and an uppercut. Parry or dodge these moves and use the enemy's aggression to your advantage. Be wary of the newly added leaping slam and adjust your position accordingly.

Keep a close watch on your stamina to avoid exhaustion during the Viper's sustained combos. Upon defeating the Viper, you'll earn over 10,000 Lacrima, Hismar's Scale, several Fallen Lord items, and the Hunter's Ring.
