In the thrilling world of *Dungeon Fighter Online*, the dragonkin have long posed a formidable challenge to heroes, and this continues in *The First Berserker: Khazan*. Here, players face the daunting task of defeating the Viper, a high-ranking dragonkin engineered by Hismar to lead and perpetuate chaos among the defeated dragons. Facing this powerful adversary requires a strategic approach, so let's dive into how to effectively conquer the Viper in *The First Berserker: Khazan*.
Phase 1

- A three-hit combo consisting of two stabs followed by a spear swing.
- A two-hit combo where the Viper swings its spear from left to right.
- A large sweep, followed by a leap away, and then throws its spear up to two times; keep an eye on the returning weapon.
- A four-hit combo involving a spinning spear, followed by swipes in both directions.
Mastering the art of blocking and executing Perfect Guards will swiftly drain the Viper's stamina. Maintain relentless pressure with regular and Brutal Attacks when opportunities arise. The Spirit of Advocacy can serve as a valuable decoy, diverting the Viper's attention. Be prepared for the Viper to summon an energy tornado at half health, indicated by a roar; swiftly move away to avoid being pulled into it.

All of the Viper's previous attacks will now be more potent and include additional hits, so constant blocking is advisable. Successfully executing a Perfect Guard on the final hit of its five-hit combo will stagger the boss, providing a prime opportunity for significant damage. Once you deplete its health, the true battle begins.
Phase 2

When the Viper's health reaches the halfway mark, it will summon a storm, dimming the arena. During lightning flashes, the Viper will leap towards you for attacks, repeating this several times before charging and executing an uppercut. Parry or dodge these moves, using the Viper's aggressive behavior to your advantage. Be mindful of its new leaping slam attack and adjust your positioning accordingly.
Always monitor your stamina to avoid exhaustion, which could leave you vulnerable to the Viper's sustained combos. Successfully defeating the Viper 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 tackle the Viper in *The First Berserker: Khazan*. For further assistance with the game, feel free to explore resources on The Escapist.
