Nuclear Battery Idol

The Nuclear Battery Idol is a merchant item used to move the Brave Merchant into a habitable room. It is not a placeable base structure itself; instead, it serves as a condition item that affects the merchant’s ability to relocate.

In practice, the Nuclear Battery Idol is part of the process of bringing the Brave Merchant into a room that meets the game’s housing requirements. Once the room is considered habitable, the merchant can move in and operate from that location. This makes the item relevant for players who are setting up merchant housing or reorganizing NPC placements within their base.

Because its function is tied to merchant relocation, the Nuclear Battery Idol is most useful when preparing a suitable room rather than as a combat or progression item. Players should ensure the room is fully ready as a habitable space before relying on it for the Brave Merchant, since the item’s purpose is to enable that move rather than to replace the housing requirements themselves.
