Underground Castle 4 is currently a popular dungeon adventure game, featuring an engaging story and a rich cast of characters as an interesting RPG mobile game. All players can choose their favorite characters to develop. So, how do you defeat the boss in the Hall of Wraiths in Underground Castle 4? The game features many dungeons and different unique sections. During the dungeon exploration, you may also encounter extremely difficult bosses. It's not an easy task to quickly defeat them. Therefore, today we will provide a detailed guide on how to handle the Hall of Wraiths.

The Hall of Wraiths is one of the more challenging dungeons in the game, with a uniquely designed map that makes it feel like you're truly in the underworld. All players need to master the specific special mechanisms to successfully clear the dungeon. Gaining a deep understanding of the related strategies will greatly benefit you. First, understand the core mechanisms and team composition. In the team, it is recommended to use 6 mages, with the Treant Army being the best choice. When making decisions, avoid the Bone Language series, as they have almost no effect in this scenario and are considered ineffective roles. During the process of configuring your lineup, ensure that your team has strong resistance to physical attacks, which will allow for a 200% bonus to magic damage.

Preliminary conditions are also a critical part. Obtaining the key is a prerequisite for entering the Hall of Wraiths corridor. Players can find the key in the adjacent maps on either side, but the key drop location is not fixed. You can farm elite monsters in both maps, with a 30% chance of dropping the key. When attacking the boss, the process is divided into three stages, each requiring different strategies.

In the first stage, the boss will release red circles around it, primarily using ground-based red circle attacks. At this point, keep the entire team spread out. The boss will periodically summon various small monsters; these must be quickly defeated. Each time a small monster is killed, the team's attributes increase by 20%, and this effect lasts for 5 minutes, stacking up to three times. The second stage is a crucial period for attacking the boss. The boss will summon four clones, each with very high attack power. A slight mistake could lead to a rapid drop in player health. Gather the team to focus fire on the real boss, which is marked by a purple aura under its feet among the multiple bosses. At this time, there will also be chests refreshing on the map, with a 35% chance of obtaining high-level equipment upon opening. In the final stage, all combat power needs to be maximized. The boss has extremely high burst damage, and you can adopt a rhythm of output and displacement output, ultimately defeating the boss.

This concludes the guide on how to defeat the boss in the Hall of Wraiths in Underground Castle 4. This dungeon's boss has extremely high health and hides many interactive points. Players need to gather their teams and find the corresponding attack strategies based on the different stages of the boss.
