In the game “Once Human,” Arachsiam is among the initial formidable foes. Although it’s not overly challenging to defeat, a unique feature of its combat mechanics has left many players puzzled. This guide offers an explanation of all Arachsiam’s mechanics and some strategies for efficiently overcoming it.

How To Beat Arachsiam In Once Human

As a seasoned adventurer with countless battles under my belt, I can confidently say that facing Arachsiam is no walk in the park. This boss towers above the Treant and Ravenous Hunter in terms of threat level. With legs as massive as oak trees, it can swipe at us players with surprising speed and force. The real danger, however, lies in its ability to spit out webs that ensnare anyone who dares touch them. Once caught, we’re left helpless, open to attacks from the boss or its minions.

When facing Arachsiam, keep a sharp eye on your surroundings. Dodge its web projectiles and quickly eliminate any spiders it releases. Be prepared for unexpected attacks from the boss, as it can strike randomly.

In the challenging difficulty level, you’ll have to find a method to manage the large groups of spiders and other creatures that Arachnid Sovereign summons. You can utilize combat Deviants such as Zeno-Purifier, Lonewolf’s Whisper, and Mini Feaster effectively during this battle. However, if possible, seek out a group to team up with for better results.

Destroy the Eggs

Over time, Arachsiam will shroud the arena in fog and become invincible. To reactivate her vulnerability, search for and eliminate spider eggs located beyond the arena. Look at the other ends of the web bridges and the arena walls. The eggs are identifiable by their distinctive purple glow, even through the mist. If no more eggs remain outside, inspect the arena itself. If all eggs have been eradicated, simply wait a while, avoiding Arachsiam’s assaults. Eventually, her shield will deactivate on its own.
