Lord Inquisitor Seru has two pre-requirements that your raid must meet before you consider attempting him.
1) You need at least 1 person with the Arx Key. This key allows a player to port their group up to the temple where he resides. It can be used from any zone in the game that allows porting. A guide can be found HERE. The more keys your raid has the faster everyone can port up.
2) Melee should have Seru Bane Weapons (Guide HERE). He is immune to normal melee attacks.
After using the Arx Key and porting up to his temple you’ll need to find him. His chambers are behind a maze. This maze is easy to navigate now that we have maps in the game.
Follow the arrows on the maps below to get to the maze area. You’ll see a little statue you can click on that will port you to it.
See map below to get through the maze.
