Magic cancellation

Magic cancellation or shortly MC is a property of some pieces of armour which protects against a wide variety of special melee attacks. It has some similar effects as zapping a monster with a wand of cancellation. Magic cancellation is different from the extrinsic magic resistance.

Protects Against

Magic cancellation reduces the chance of success of melee attacks that can be considered of a magical nature. It protects against the following:

• Fire (e.g. fire ant burning attack)
• Cold (e.g. winter wolf breath)
• Shock (e.g. homunculus bite)
• Sleep (e.g. electric eel bite)
• Poison (e.g. killer bee sting)
• Paralysis (e.g. guardian naga bite)
• Drain life (e.g. vampire bite)
• Sticky attack (e.g. large mimic bite)
• Lycanthropy (e.g. the werejackal bite when it is in animal form)
• Slowing attack (e.g. Shade touch)
• Teleport by the quantum mechanic claw
• Sliming by the green slime touch
• Disenchanting by the disenchanter touch and claw
• Power draining by the energy vortex
• Constitution draining poison by the rabid rat bite
• Dexterity draining poison by the quasit claw

Does NOT protect against

Magic cancellation does not protect against the following attacks:

• Ordinary physical damage including weapons, spitting, exploding and tentacle attacks
• Spells
• Gaze attacks
• Breath attacks
• Grabbing attacks
• Engulfing
• Passive attacks
• Erosion attacks, including rusting, corroding and rotting
• Drowning attacks
• Blinding attacks
• Confusion attacks
• Hallucination attacks
• Stunning attacks
• Petrification attacks
• Acid attacks
• Seduction
• Mindflayer intelligence drain
• Leprechaun gold stealing
• Nymph item stealing
• Wizard of Yendor amulet stealing
• Gremlin intrinsic-stealing
• Xan leg attack
• Nurse healing attack
• Juiblex disease attack
• Special attacks of the Riders

Effectiveness

Magic cancellation is a whole number from zero (no reduction in the chance of special attacks succeeding) to 3 (special attacks have 2% of their normal chance of success). The relationship between MC level and chance of special attack success is as follows:

• Magic Cancellation 0 = 100%
• Magic Cancellation 1 = ~67%
• Magic Cancellation 2 = ~35%
• Magic Cancellation 3 = 2%
• Monster cancelled by wand or spell = 0%

All cloaks, some pieces of body armour and the cornuthaum provide non-zero magic cancellation. Note that magic cancellation is not cumulative - your magic cancellation is the maximum of that provided by any single piece of your armour. The following items have maximum magic cancellation (3):

• Elven mithril-coat
• Dwarvish mithril-coat
• Elven cloak
• Oilskin cloak
• Robe
• Cloak of protection
• Cloak of magic resistance

Most players like to have maximum magic cancellation, but some favour the benefits conferred by a cloak of displacement (MC 2).
