The Vestment of Hell
|[ The Vestment of Hell
In dNetHack the Vestment is an artifact opera cloak which grants fire resistance when carried, and acid resistance and half physical damage when worn, in addition to whatever benefit is provided by the cloak with the "opera cloak" randomized appearance in the game: displacement, invisibility, magic resistance, protection. Also, its armor class is double that of its base item.
In vanilla NetHack, the "opera cloak" random appearance has a magenta tile ([). The Noble patch changes the color of this tile to black ([).
As the Vestment has a randomized cloak as its base item, its usefulness may vary between games. While there are no cloaks with randomized appearances in dNetHack that are a liability to their wearer, some cloak types may be especially useful combined with the other extrinsics of the Vestment. If its base item is a cloak of protection, then the Vestment adds a formidable six points to your AC, not counting enchantment, plus maximum magic cancellation, eliminating the need for Victorian underwear. Other base cloaks offer only two points of default AC and MC2, but displacement, invisibility, or magic resistance may still be desirable extrinsics in addition to the default fire and acid resistance, and half physical damage.
The Vestment's acid resistance by itself is quite nice, as there are few other items that confer it—notably the alchemy smock, which the Vestment can easily replace. (In this respect the Vestment may have an advantage over its non-vampiric counterpart, the Mantle of Heaven.) The Vestment can also replace the much heavier dNetHack-specific Leo nemaeus hide as a source of the half physical damage intrinsic.
