[Damage Type]
Every attack in NetHack has a defined damage type. This determines how the attack of a monster or character affects the target when it hits (as opposed to attack type, which determines how the attack makes contact with the target). There are many damage types and many effects for the wide assortment of monsters in NetHack.[1]
Many damage types actually cause no hit point damage.
If a monster is cancelled, many of its damage types will have no effect.
Magic cancellation can negate the effect of many damage types, but only for certain attack types and damage types.

Effect of cancellation
If the attacker is cancelled, then several attack types are blocked, and most special damage types are blocked. Cancellation is effective if either the attack type or the damage type are blocked.
These damage types are not blocked: ordinary physical damage, magic missile, disintegration, digestion, drain intelligence, illness, rider special damage types, steal the Amulet.
For example, if a dragon is cancelled, its breath attack is blocked, and will do no damage, no matter what the damage type.
Effect of magic cancellation
Magic cancellation (not to be confused with cancellation) is a property that the hero may have which blocks certain attacks. Magic cancellation is effective only if the attack has both an eligible attack type and an eligible damage type. And even then, there is only a probability of blocking the attack.
These damage types are eligible for magic cancellation: fire, cold, sleep, shock, poison (vs strength, vs dexterity, and vs constitution), slow, paralysis, drain life, drain energy, sticking, teleport, lycanthropy, sliming, disenchanting.
History
Starting with NetHack 3.6.0:[2]
- Half physical damage blocks more instances of physical damage than it did in NetHack 3.4.3.
- Grease protects against all types of erosion.
- Passive fire damage may burn the attacker's weapon.
- Passive attacks no longer erode armor covered by other armor.
- AD_DREN implemented, actually draining energy (energy vortices).
Starting with NetHack 3.6.1:[3]
- AD_SAMU may take any quest artifact. In earlier versions, AD_SAMU would not take a quest artifact belonging to a role different from the hero's role.
Starting with NetHack 3.6.2:[4]
- If hero survives sliming via lifesaving, hero continues adventuring in slime form.
- If AD_TLPT succeeds in teleporting, hit point damage is limited so that defender will not die from hit point loss.
