In Welcome to Elderfield, I can swear loyalty to one eldritch deity at the church every Sunday. My choice affects my stats, but it also determines which deity-specific room I can access during that week. These hidden rooms contain useful items and treasures that can make progression a little easier.
Treasure Rooms of the Old Gods
In this guide, I list the eldritch deity rooms I have found in Welcome to Elderfield, where I can find each one, and what is available inside. Because I can only follow one god at a time, I can normally only access one of these rooms per week.
Room of Daeus

I can find the room of Daeus, the God of the Deep, in the mall hallways right next to the elevator. This will likely be the first deity room I can access. Inside, I can find bait, a fishing potion, and food that boosts luck for one day.
Room of Gatis

I can find the room of Gatis, the God of the Moon, on the western floor 3 staircase of the Greystone Estates. To reach this area, I first need to accept the “Penpals” task from the notice board and speak with Brittany in the middle house of the three houses south of the estates. I have not opened this room yet.
Room of Nezroth

I can find the room of Nezroth, the God of Flesh, on level 2 of the mall mines. I access the mines through the Food Court in the mall. Inside the room, I can find strong healing items and a Crimson Die, which boosts a dice roll.
Room of Delvek

I can find the room of Delvek, the God of Mysteries, on level 2 of the mall mines. To access it, I first enter Nezroth’s room and then reset resources, such as by bathing for the first time during that week. Inside, I can find small keys that can be used in the mines, along with plenty of gold.
