Build a Valid NPC Room in Delverium

Updated October 2, 2026 · Delverium Guide

The community building reference requires enclosed walls, flooring, a door, light and a bed, with an internal room size from 2×3 to 24×24 tiles. A developer reply explains Assign Bed: Auto Select assigns as needed, None reserves it for players, and a named NPC forces that room assignment.

Community room reference + Mar 1, 2026 demo-era bed options; Sep 25 Early Access patch still mentions manual room reassignment. Exact menu layout can differ.

Check the room before assigning a villager

1. Inspect the interior, not the outer building footprint. The wiki's documented range is at least 2×3 and at most 24×24 internal tiles.
2. Check walls, flooring and a door, then a light source and a bed. Treat a missing component as the first thing to fix before recruiting another NPC.
3. Interact with the bed and inspect the room dialog. If your current build does not show the same options, follow its visible room status and compare with the dated source.

Choose the assignment that matches your intent

If an NPC moved into your own room while their intended room was incomplete, finish the intended room and assign its bed to that NPC. Use None for a bed you want reserved for players; this is the practical distinction in the original developer answer.

Check the result and handle an older stuck save

Confirm the intended room assignment, then check whether the villager returns. The September 25 patch fixed a respawn-after-reload issue but specifically said older saves with stuck NPCs still needed manual reassignment. Use the recovery guide if the assignment is valid and the NPC remains absent.

A room is not a full recruitment condition

These sources establish room construction and assignment. They do not prove that every NPC can be recruited just by building an empty room, or give a universal time until an assigned villager appears.
