For invisible characters, the cloak of magic resistance is difficult to distinguish from a [[cloak of invisibility]] because neither one will self-identify when worn. One way to identify the cloak of magic resistance is to wear it and step onto an anti-magic field, polymorph trap, teleportation trap, or be subject to a wand of striking. Be sure that you do not have magic resistance from any other source, such as wielding [[Magicbane]] or carrying certain quest artifacts. If you have magic resistance, the effect will be nullified. Beware, though, that if the cloak is '''not''' magic resistance, you will suffer the effect in question.  A safer approach is to zap a wand of [[enlightenment]] and look for the line "You are magic-protected".

The cloak of magic resistance is the only [[Randomized appearance|randomized]] cloak that does not [[auto-identify]] on use at all or when taking effect, making it relatively trivial to informally identify.

Some of the riskier methods to identify a worn cloak of magic resistance is to remove, stash or disable all other sources of magic resistance, then step onto an [[anti-magic field]] or [[teleportation trap]]; unless you are playing a weak or early character, giving a hostile monster a wand of striking can also work. If you have magic resistance, the effect will be nullified. Using a [[wand of enlightenment]] in this scenario is far safer, but less likely due to the wand's rarity.

The cloak of magic resistance (commonly abbreviated CoMR) is an item that appears in NetHack. It is made of cloth.

Generation

All Wizards start the game with a cloak of magic resistance.

Aligned priests - including high priests and the Arch Priest, the Priest quest leader - have a 121 chance to be generated with a cloak of magic resistance.[1] Master Kaen, the Monk quest nemesis, has a 111 chance of being generated with a cloak of magic resistance, and will otherwise generate with a robe.[2]

Non-monk player monsters on the Astral Plane have a 87.5% chance of receiving a random magical cloak, and a further 12.5% chance of that cloak being a cloak of magic resistance, effectively ~10.94%;[3] monks are special-cased to always generate wearing robes.[4] For priests, there is a 75% chance that the cloak will be made into a robe instead, reducing this effective chance to ~2.73%.[5] Wizards have a 12 of similarly forcing a cloak of magic resistance, resulting in an effective chance of 43.75%.[6]

Effects

When worn, the cloak simply provides 1 AC, MC1 and magic resistance. Its secondary effect is not affected by burning.

Strategy

The cloak of magic resistance is considered a ubiquitous part of many ascension kits, and is frequently paired with silver dragon scale mail.

Identification

The cloak of magic resistance is the only randomized cloak that does not auto-identify on use at all or when taking effect, making it relatively trivial to informally identify. Invisible characters will want to remove their source of invisibility if possible (or else let it expire if obtained via spell or potion) prior to wear-testing a cloak to ensure it is not a cloak of invisibility instead.

Some of the riskier methods to identify a worn cloak of magic resistance is to remove, stash or disable all other sources of magic resistance, then step onto an anti-magic field or teleportation trap; unless you are playing a weak or early character, giving a hostile monster a wand of striking can also work. If you have magic resistance, the effect will be nullified. Using a wand of enlightenment in this scenario is far safer, but less likely due to the wand's rarity.

History

In NetHack 3.4.3 and earlier versions, the cloak gave MC3.

Variants

In general, variants based on version 3.4.3 have the cloak of magic resistance retain MC3.

SLASH'EM

In SLASH'EM, the cloak of magic resistance is the same as it was in NetHack 3.4.3 and earlier versions.

Undead vampires are often generated with opera cloaks, providing a reliable source if the cloak of magic resistance has the opera cloak as its randomized appearance; however, the vampires' magic resistance will give more spellcasting-reliant characters significant trouble, especially in the case of the powerful vampire mages.

A cloak of magic resistance can be created by upgrading.

FIQHack

In FIQHack the cloak of magic resistance is MC2.
