In the thrilling universe of *Dungeon Fighter Online*, the dragonkin have long been a formidable challenge for heroes, and this trend continues with *The First Berserker: Khazan*. Here, players face off against the menacing Viper, a high-ranking dragonkin created by Hismar, tasked with leading the defeated dragons to sow chaos. To conquer this powerful adversary, it's crucial to approach the battle with strategy and caution.

Before engaging the Viper, ensure your skills are optimized for your chosen weapon. Summon the Spirit of Advocacy just outside the boss gates for additional support. When facing the Viper, be vigilant for its attack patterns:

  • 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, then throwing its spear up to two times; be wary of the returning weapon.
  • A four-hit combo with a spinning spear, followed by swipes in both directions.

Mastering the art of timing your blocks and executing Perfect Guards will rapidly deplete the Viper's stamina. Maintain relentless pressure with attacks and Brutal Attacks whenever possible. The Spirit of Advocacy can serve as a useful decoy, drawing the Viper's attention away from you. When the boss's health drops to about half, it will roar and summon an energy tornado. Quickly move away to avoid being drawn into it.

Following the energy blast, be prepared for the Viper's leaping slam. Watch for its grab attack, indicated by the flashing spear tip, and dodge to the right to evade it. The Viper will also employ a new ranged attack, spinning its spear vertically, followed by a series of jumping attacks.

All of its previous attacks will now be more potent and include additional hits. Constant blocking is advisable for safety. 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 significant damage. Once you've depleted its health, the true challenge begins.

Phase 2

In Phase 2, the Viper taps into Hismar's power, restoring its health and becoming even more formidable. 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 seize your opportunity.

As you reduce its health to the halfway mark, the Viper will summon a storm, dimming 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, using its aggression to your advantage. Be mindful of its new leaping slam and adjust your position accordingly.

Always monitor your stamina to avoid exhaustion 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 overcome the Viper in *The First Berserker: Khazan*. For further assistance with the game, visit The Escapist.
