In the expansive world of *Dungeon Fighter Online*, the dragonkin, particularly the Viper, have long been a formidable challenge for heroes. As players delve into *The First Berserker: Khazan*, they'll find themselves facing this notorious adversary once again. To conquer the Viper, strategic planning and precise execution are essential. Here's a detailed guide on how to triumph over this high-ranking dragonkin, created by Hismar, in *The First Berserker: Khazan*.
How to Beat Viper in The First Berserker: Khazan
Phase 1

Before confronting the Viper, ensure your skills are optimized for your chosen weapon. For an added advantage, summon the Spirit of Advocacy just outside the boss gates. This spirit can serve as a decoy, drawing the Viper's attention and providing you with crucial moments to attack. When facing the Viper, be vigilant for its diverse attack patterns:
- A three-hit combo starting with two stabs followed by a spear swing.
- A two-hit spear-swinging combo moving from left to right.
- A large sweep followed by a leap away, after which the Viper throws its spear up to two times; be wary of the returning weapon.
- A four-hit combo featuring 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. Seize every opportunity to launch aggressive attacks and Brutal Attacks. When the Viper's health drops to about half, it will roar and summon an energy tornado. Quickly retreat to avoid being caught in the vortex.

Post-energy blast, be prepared for the Viper's leaping slam and a new grab attack, indicated by the flashing tip of its spear. Dodge to the right to evade this move. Additionally, the Viper now employs a ranged attack where it sends its spear spinning vertically, followed by a pair of jumping attacks. Its earlier attacks now pack more punch and have additional hits, so maintain a defensive stance and block frequently. A successful Perfect Guard on the final hit of its now five-hit combo will stagger the Viper, opening a window for significant damage. The real challenge begins once you've depleted its health bar.
Phase 2

In Phase 2, the Viper taps into Hismar's power, restoring its health and enhancing its capabilities. It wields its fortified left arm for devastating downward smashes and swipes, and a giant sword for slashing attacks. When the Viper roars, brace for two wide-ranging arm attacks followed by a Burst Attack. Use this moment to deploy a Counterattack, which will stun the Viper and provide a critical opportunity to strike.
Once the Viper's health reaches the halfway mark, it will summon a storm that darkens the arena. Watch for lightning flashes, as the Viper will use these moments to leap and attack. It will perform this maneuver several times, culminating in a charge followed by an uppercut. Parry or dodge these attacks, and exploit the Viper's aggressive behavior. Be mindful of a new leaping slam in its arsenal and adjust your positioning accordingly.
Throughout the fight, monitor your stamina closely to avoid exhaustion during the Viper's sustained combos. Successfully defeating the Viper will reward you with over 10,000 Lacrima, Hismar's Scale, various Fallen Lord items, and the coveted Hunter's Ring.
