 ==History==
 The ring of protection 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]]. From this version to [[NetHack 3.4.3]], including some variants based on those versions, the ring of protection has no effect on [[Magic cancellation (3.4.3)|magic cancellation]].
 The ring of protection augmenting magic cancellation is introduced in [[NetHack 3.6.0]].
