How to Defeat the Hidden Boss Necrolord in Lost Castle 2: A Speedrun Guide

The hidden Boss of Lost Castle 2, the Lord of the Undead, is one of the most challenging enemies in the game, with harsh unlocking conditions and extremely high combat difficulty. Today, let's take a look at how to defeat the hidden boss in Lost Castle 2. Players need to complete three playthroughs and unlock nightmare difficulty, then talk to the NPC, the Old Hunter, three times in a specific room on the fifth level, to obtain the Soul Crystal Core, which allows access to the hidden level. The Lord of the Undead has two phases, each with complex attack patterns, and a slight mistake can lead to instant death.

The first phase of the Lord of the Undead is relatively simple but still requires careful handling. The Boss uses four main skills: Scythe Slash (a straight-line attack that needs to be dodged sideways), Large Area Magic Burst (ground explosions, watch for red circle warnings), Black Thunderstorm (full-screen lightning, must keep moving to avoid paralysis), and Dark Magic Balls (magic bullets fired clockwise, requiring circular movement). The Black Thunderstorm is the most threatening; being hit by it may lead to getting killed by follow-up combos, so it's recommended to prioritize dodging the lightning rather than attacking greedily. The core strategy for this phase is to keep moving, using jump attacks to chip away at health, and avoiding standing still to fight head-on.

Entering the second phase, the battle difficulty increases significantly as the Lord of the Undead transforms into a giant demon form with nine different attack methods. These include Claw Strike (multi-segment tracking, need to predict landing points), Magic Ball Barrage (full-screen bullet hell, dodge by running in large circles), and Charged Cannon (Y-axis attack, move up and down to dodge). The most dangerous combo is Black Lightning + Ground Explosion + Claw Strike; once paralyzed by the lightning, subsequent attacks are almost guaranteed hits. The approach is to closely watch the Boss's limb movements, plan your positioning in advance, prioritize dodging the lightning, and then find a safe spot to deal damage.

It's recommended to use high-damage weapons (such as fire-attribute or high-crit gear) for the fight. At the beginning of the second phase, you can place Banana Peels at the edge of the arena, using the invincibility frames from falling to avoid lethal skills. The main opportunities to deal damage are during the Boss's post-attack cooldown periods, such as after the Claw Strike lands or the Charged Cannon ends. Also, the Boss's head and claws are the only parts that can be attacked, so aim precisely to avoid wasting attacks.

The key to defeating the Lord of the Undead lies in patient observation, precise positioning, and rational damage output. New players are advised to first level their character to above level 110 and familiarize themselves with the Boss's attack patterns before attempting the challenge. Mastering these techniques will help you stand out in the ultimate trial of Lost Castle 2, reaping rich rewards and achievements.
