Lower Reaches

The Lower Reaches of the Sewers under Temple District, also known as The Forgotten Believers—Temple City, aka The Rift Area.

You can access this area through the refuge of the Cult of Unseeing Eye, known as The Old Tunnels.

Ahead of the entry zone is a trapped "screaming" statue. Click on its description area will spawn a wandering horror and two sword spiders, indefinitely. There is a trapped treasure stash in the face of the statue which you can loot without any enemies appearing.

Go down the east corridor to find two spawn points, one of them is likely a group of Yuanti warriors and mages. You may also get many gibberlings or six mummies/ghasts instead.

Continue through the hallway. You will reach a large room. There is a broken bridge than needs repairing to get across. There is a petrification trap on the stairs up to the bridge so make sure to disarm that. On the other side there is a stash with Ashideena, a warhammer +2 on the southeastern side of the bridge.

Click on the broken bridge and a guardian speaks to you. It will give you three riddles. The answers are "Life," "Time," and "The current one.' The two halves of the bridge will then be connected. Go across it. On the other side of the structure, there will be a certain number of Gauths and/or Beholders, depending on your party's level.

Go past the area with the Beholders. Follow the hallway leading north from that area. There is a petrification trap on the center jetty at the end of the hallway. Follow the central jetty until you come to a temple. The Diseased One will speak to you. After that, enter the Temple of a Forgotten God. You will be attacked by an Emphatic Manifestation. The only way to defeat it is to cast a healing spell or use the rod of resurrection on it. The party will receive 25,750 experience points at this stage.

After that, an avatar of Amaunator will speak with you. It will tell you about the rod, then give you half of it in form of the Rift Device Part. On the altar behind it is a treasure stash.
