Fuse

Fuses are the key items of The Mines, the way room keys are in The Hotel. They look like industrial cage-style lamps with a brown metal base and two pins under it, and they are used to power the generators in gated rooms. When enough are in place and the generator is switched on, a button next to the metal gate opens it and the next room becomes reachable.

How many are needed

Most generators take two fuses, but some take one or three. The number depends on the room, not on chance: the long eight-door generator room always needs three and the very small generator room needs one. Only the required amount spawns. They show up in item lockers, on wooden tables, in wooden drawers and in toolboxes, or on the ground in front of the generator when the room has no containers. When placed, they glow blue, yellow and red in order.

Handling

A player can carry up to three, and fuses take half the usual inventory space. They cannot be put in the Rift. After the patch of February 21, 2025, they make the same shimmering sound as other Guiding Light items, and lockers show a blue light around them.

Special cases

The Dam generator already has its fuses, since September 1, 2024, and The Adit always has a generator missing two.
