The Viper, a high-ranking dragonkin created by Hismar to lead defeated dragons and sow chaos, is a formidable foe even without tapping into Hismar's power. Before facing the Viper, ensure your skills are set up for your chosen weapon, and consider summoning the Spirit of Advocacy just outside the boss gates for additional support. When confronting the Viper, be wary of the following attacks:

  • A three-hit combo beginning with two stabs and ending with 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; watch out for the returning weapon.
  • A four-hit combo that includes a spinning spear and swipes in both directions.

Timing your blocks and executing Perfect Guards will quickly deplete the Viper's stamina. Keep up the pressure with more attacks and Brutal Attacks whenever possible. The Spirit of Advocacy can act as a decoy, significantly aiding your strategy. When the Viper's health reaches about half, it will roar and summon an energy tornado around itself. Move away to avoid being pulled into the vortex.

Following the energy blast, be alert for its leaping slam. The Viper will now attempt a grab attack, indicated by the flashing tip of its spear; dodge to the right to avoid it. It also introduces a new ranged attack where it sends the spear spinning vertically, followed by a pair of jumping attacks. All previous attacks now deal more damage and include additional hits, so maintain a defensive stance and block frequently. If you can execute a Perfect Guard on the final hit of its five-hit combo, you'll stagger the boss, opening a window for massive damage.

After reducing the Viper's health to zero, the real battle begins.

Phase 2

In Phase 2, the Viper taps into Hismar's power, becoming a more fearsome adversary with a fully restored health bar. It uses its fortified left arm for downward smashes and swipes, and wields a giant sword for slashes. When it roars, brace for two wide-ranging arm attacks followed by a Burst Attack; use a Counterattack to stun it and create an attack opportunity.

When the Viper's health drops to the halfway point, it summons a storm that dims the arena. During lightning flashes, the Viper will leap towards you to attack multiple times, ending with a charge and an uppercut. Parry or dodge these attacks, and exploit its aggressive behavior. It also adds a leaping slam to its attacks, so adjust your position accordingly.

Monitor your stamina closely to avoid exhaustion and vulnerability 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.
