Dwarvish iron helm
|[ dwarvish iron helm
Player dwarves start the game with knowledge of the dwarvish iron helm. Any dwarven character that would start the game with a helmet will start with a dwarvish iron helm instead - currently, there are no applicable roles where this substitution would occur.
In addition to random generation, armor shops and general stores can stock dwarvish iron helms.
When worn, a dwarvish iron helm grants a base AC of 2.
The dwarvish iron helm is the only helm with 2 AC, and is usually the best helm available in the early- and mid-game for builds that are not significantly reliant on spellcasting. It is also among the heavier helms, and is susceptible to rust traps and rust monsters, making rustproofing necessary to preserve its AC.
In the mid-game, the dwarvish iron helm is often discarded in favor of other helms that provide additional benefits beyond the basics, especially for ascension kits - the helm of telepathy and the helm of brilliance are particular candidates. While the elven leather helm does not protect your head from falling objects, they do not interfere with spellcasting and can safely be enchanted to +7; falling objects are also rarely a concern beyond the early game.
The dwarvish iron helm first appears in NetHack 3.0.0.
In variants with object materials systems, a dwarvish iron helm is sometimes called a dwarvish helm, with iron as its base material - they may also have their material appended within the name, depending on the variant (e.g., "a +0 dwarvish mithril helm"). Some variants may give dwarves (including the player) an AC bonus for wearing a dwarvish iron helm.
In UnNetHack, the dwarvish iron helm grants +1 AC to dwarves that wear them, including player dwarves.
In dNetHack, a dwarvish helm grants 1 AC and 1 DR when worn, and has a built-in lantern that can be turned on or off by applying the helm. Dwarves that generate in dark levels within the Gnomish Mines will have their helm's lantern lit.
In EvilHack, the dwarvish helm grants +1 AC to dwarves that wear them, including player dwarves. Dwarven Knights start the game with a +0 dwarvish helm in place of the standard helmet.
In Hack'EM, the dwarvish iron helm grants +1 AC to dwarves that wear them, including player dwarves. Dwarven Undead Slayers that start the game with a helmet will instead start with a +0 dwarvish iron helm.
Upgrading an orcish helm will produce a dwarvish helm as in SLASH'EM, but upgrading a dwarvish helm will only produce an orcish helm. Forging recipes and other details are the same as in SLASH'EM and EvilHack.
