Wolcen: Lords of Mayhem – Pacified Experiment Boss Guide

Pacified Experiment is one of the many alpha bosses in Wolcen: Lords of Mayhem, and can be found in Act 3, following the Infiltration mission from the main campaign.

This encounter involves massive mech, along with a rather weak demon called Ydrael. Here’s our step-by-step guide, along with everything you need to know before embarking on this fight.

Types of Attacks

  • It embodies itself in electricity and charges forward quickly, but the path is marked with the red visual cue
  • Charges and fires a laser beam on a marked zone
  • Lifts up its arm and charges a laser beam, pounding the ground after a few seconds and leaving a few electricity orbs in the air upon impact
  • Charges a multi directional attack marked by 4 red cue paths, creating an energy shock that causes damage in said areas


Loot is completely randomized, but there are at least some Epic gear items in yellow color guaranteed.

Pacified Experiment Strategy

Pacified Experiment #P90 isn’t one of the hardest fights in Wolcen by any means, it’s only the timing that is unfortunate as this isn’t a regular encounter. You’re gonna have to survive multiple enemy waves, and the last one will trigger the boss fight. Along with the giant robot, the demon Ydrael will show up, but treat it as a regular enemy as it doesn’t presents a major challenge.

That being said, the robot can be a bit troublesome. It only carries a handful of attacks, but they are all powerful, and usually covering a wide area. The best to do is to replicate what we’ve learned so far with other boss encounters, trusting the red visual cues on the floor and acting accordingly.

Attack windows tend to appear after or even during these, which is the case for the massive multi directional attack. If you happen to be outside the danger zone, approach the robot and make haste (this in case you’re using a melee-focused character, if not, just dodge and keep on shooting and using magic whenever possible):
