In the *Dungeon Fighter Online* universe, the dragonkin have long been a formidable challenge for heroes, and this continues in *The First Berserker: Khazan*. Players must exercise caution when facing the Viper, a high-ranking dragonkin created by Hismar to lead defeated dragons and sow chaos. Here's how to tackle this powerful adversary in *The First Berserker: Khazan*.
Phase 1
After setting up your skills for your chosen weapon, summon the Spirit of Advocacy just outside the boss gates for additional support. When confronting the Viper, be vigilant for the following attacks:
- 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; watch for the returning weapon.
- A four-hit combo with a spinning spear, followed by swipes in both directions.
Timing your blocks and executing Perfect Guards will deplete the Viper's stamina quickly. Continue to pressure it with attacks and Brutal Attacks whenever possible. The Spirit of Advocacy can serve as an effective decoy. At about half health, the Viper will roar and summon an energy tornado, so retreat to avoid being pulled in.
After the energy blast, beware of its leaping slam. The Viper will now use its grab attack, indicated by a flashing spear tip, so dodge to the right. It also introduces a new ranged attack, sending the spear spinning vertically, followed by jumping attacks.
All of its previous attacks now deal more damage and have additional hits, so maintaining a defensive stance is crucial. Executing a Perfect Guard on the final hit of its five-hit combo will stagger the Viper, allowing you to deal significant damage.
Once you've depleted its health, the true battle begins.
Phase 2
In this phase, the Viper taps into Hismar's power, regaining a full health bar and becoming more formidable. It uses its fortified left arm for downward smashes and swipes, and its 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 an opportunity for attack.
At half health, the Viper summons a storm that darkens the arena. During lightning flashes, it will leap to attack you multiple times, ending with a charge and an uppercut. Parry or dodge these attacks, using the Viper's aggression to your advantage. Be prepared for the new leaping slam attack and adjust your positioning accordingly.
Monitor your stamina closely to avoid becoming vulnerable 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.
