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

• A three-hit combo beginning with two stabs followed by a spear swing.
• A two-hit spear-swinging combo from left to right.
• A large sweep followed by a leap away, then up to two spear throws which you need to dodge as the weapon returns.
• A four-hit combo featuring a spinning spear and subsequent swipes in both directions.

Effective blocking and executing Perfect Guards will quickly drain the Viper's stamina. Continuously pressure it with attacks and Brutal Attacks when possible. The Spirit of Advocacy can serve as a crucial decoy. At half health, the Viper will roar and summon an energy tornado; move away promptly to avoid being pulled in.

Post-energy blast, anticipate a leaping slam and watch for the Viper's grab attack, indicated by the spear's flashing tip; dodge to the right to evade it. Be prepared for a new ranged attack where the spear spins vertically, followed by a pair of jumping attacks.

The Viper's attacks now pack more punch and include additional hits, so constant blocking is advisable. A successful Perfect Guard on the final hit of its five-hit combo can stagger it, opening a window for massive damage. Reducing its health to zero is merely the prelude to the true battle.

Phase 2

In this phase, the Viper harnesses Hismar's power, restoring its health and becoming even more dangerous. It uses its reinforced left arm for downward smashes and swipes, and a giant sword for slashes. A roar signals two wide-ranging arm attacks followed by a Burst Attack; prepare a Counterattack to stun it, creating an attack opportunity.

When its health drops to the halfway mark, it summons a storm that darkens the arena. During lightning flashes, the Viper will leap towards you for multiple attacks, culminating in a charge and an uppercut. Parry or dodge these, using the Viper's aggression to your advantage. Be ready for a new leaping slam, adjusting your position to avoid it.

Keep a close watch on your stamina to avoid exhaustion and vulnerability during the Viper's prolonged combos. Upon defeating the boss, you'll be rewarded with over 10,000 Lacrima, Hismar's Scale, various Fallen Lord items, and the Hunter's Ring.

With this guide, you should now have a clear strategy to defeat the Viper in *The First Berserker: Khazan*. For additional assistance with the game, consider searching resources at The Escapist.
