Iron

Iron is the material composing a large portion of the items in the Dungeons of Doom. Iron can corrode or rust. Rubbing iron on a touchstone produces its signature "scritch, scritch." Common iron items include long swords, skeleton keys, and most amulets. Most common metal armors, such as orcish helms or ring mail, are made out of iron.

Hitting a brown or black pudding with iron splits it into two. Polypiling iron objects may generate an iron golem.
