Plexus Sentinel

The Plexus Sentinel is an introductory boss encounter in the Manaforge Omega raid instance, acting as the first line of defense against contaminants entering the manaforge. It utilizes an Arcanomatrix Atomizer to filter out organic material from the incoming energy stream. The encounter features a brief intermission where players must survive the filtration system.

Tips

information

1. Drop the bombs on the sides

🔷 During the intermission, we strongly recommend moving the bombs to the sides of the corridor (as shown above), in order to keep the center path clear. This ensures a safe passage to the next area once the filtration mechanic ends.
