-Rust monsters are a common mid-game annoyance for players: their [[speed]] of 18 makes evasion and maintaining distance difficult, and their passive rusting reduces the amount of viable options for [[ranged attack]]s that can keep them from compromising metal armor. Fortunately, rust monsters have no [[Magic resistance (monster)|monster MR]], leaving them very vulnerable to [[wand]]s and [[spells]]. Standard unarmored [[pet]]s such as [[cat]]s and [[dog]]s can more easily deal with them without fearing retaliation.
+Rust monsters are a common mid-game annoyance for players: their [[speed]] of 18 makes evasion and maintaining distance difficult, and their passive rusting reduces the amount of viable options for [[ranged attack]]s that can keep them from compromising metal weapons armor. Fortunately, rust monsters have no [[Magic resistance (monster)|MR score]], leaving them very vulnerable to [[wand]]s and [[spells]]. Domestic pets such as [[cat]]s and [[dog]]s and other unarmored pets can more easily take down a rust monster without any trouble.
 Wearing non-metal armor or rustproofing whatever metal armor and weapons you have will render rust monster attacks completely harmless. For players who lack the means to do so, [[unicorn horn]]s are a solid backup weapon to use when fighting rust monsters, and [[Elbereth]] can push rust monsters back out of melee range, providing time and space to either fire wands and spells at them or else to remove any metallic armor before engaging in melee.
