 ** If the current enchantment is negative, the integer division by 3 could result in platform-dependent behavior: the integer expression &minus;1 / 3 may be rounded to &minus;1 or 0. The former case makes it possible to gain 4 enchantments from a blessed scroll; however, gcc and C99-compliant compilers always treat the result of integer division as an arithmetic quotient, i.e. the quotient is truncated or "rounded towards zero". In the latter case, a &minus;3 piece of armor is eligible for a 25% chance of gaining 4 enchantments from a blessed scroll, while a &minus;2 to +2 piece gains 1 to 3 points.

 Elven armor is popular for its ability to be enchanted higher than other armor, either to wear or to [[polypile]] into other types of armor that are more difficult to enchant to those same levels. [[T-shirt]]s and [[Hawaiian shirt]]s are also popular to load up with enchantments for a lightweight source of AC, though this is usually reserved for after the hero obtains [[magic resistance]] or a property such as [[unchanging]] or [[polymorph control]] to ensure that it is not destroyed by [[polymorph]]ing. A spare scroll of enchant armor can also save a [[wish]] or two when making dragon scale mail, assuming the hero can find a dragon of their desired color or create them using a cursed [[scroll of genocide]].

+The scroll of enchant armor first appears in Hack 1.21 and Hack for PDP-11, which are based on [[Jay Fenlason's Hack]], and is included in the initial item list for [[Hack 1.0]]. The use of the scroll in creating dragon scale mail is introduced in [[NetHack 3.1.0]].
 In [[NetHack 3.6.0]], cursed armor will not be made uncursed by a scroll of enchant armor due to a bug. The bug is fixed in [[NetHack 3.6.1]].
