Characteristics
Overview
A spooky heavy iron door knocker. Its haunted skull will produce flames when distrubed.
Hang it on the outside of your front door so visitors have something to knock with. It does the same job as the dragon door knocker for the same 20 metal fragments: someone knocks, and the people inside hear it.
The difference is the show. The game describes a haunted iron skull that produces flames when it is disturbed, so a knock comes with a burst of fire on your doorstep. Treat it as an effect, not a trap. Its description never says the fire hurts anyone, and it adds no protection to a wooden door or any other door. A raider gets in exactly as before.
Where it fits: a Halloween base with pumpkins in the windows and a neighbour who comes by after dark to trade. He knocks, the skull flares up, and you get a good look at him before you open. Do not count on it being in the craft menu all year, since it reads like an event item. The rest of the base decor is in the items list.
Recycling
