Poison resistance

From NetHackWiki
Jump to: navigation, search

Poison resistance is considered one of the most essential intrinsics in the game. This resistance protects against the harmful effects of poison, including instadeath. For example, a dart trap might shoot out a deadly poisoned dart.

Poison resistance does not protect you from food poisoning. It only partly protects you from the bad effects of potion of sickness.

Sources

Many corpses that offer poison resistance are themselves poisonous or otherwise dangerous (a notable exception is the corpses of shriekers, which can usually be found early). There are, however, many safe ways of acquiring poison resistance. For example, rings and amulets both include one that protects you against poison. Green dragon scale mail also protects against poison.

Barbarians, healers and orcs have a natural poison resistance. Monks get a natural poison resistance when they reach experience level 3 and tourists at level 20. Poison resistance is also granted when you are crowned.

You can safely obtain poison resistance from a corpse in one of the following ways:

  • Eat a non-poisonous corpse that grants the intrinsic.
  • Use a tinning kit to make a poisonous corpse safe (bear in mind that not all poisonous monsters grant poison resistance).
  • Wear an item that grants poison resistance. This could be a ring of poison resistance, an amulet versus poison, an alchemy smock, or green dragon scale mail or scales.
  • Use a unicorn horn to negate the strength drain caused by eating a poisonous corpse (this works because unlike poison attacks, corpse poison cannot cause instadeath, although it causes some HP loss).
  • Wear a ring of sustain ability to avoid the strength drain from eating a poisonous corpse.
  • If you know you can pray and you have lost more than 4 strength, pick up junk to be overtaxed, and pray to reverse the strength loss after eating poisonous corpses.

Very unsafe corpses

Unless you are polymorphed into a stoning-resistant form, eating any of these corpses will instantly result in YASD. If, however, you are in a stoning-resistant form before getting poison resistance, these corpses can provide it permanently. Note that tinning them does not make them safe to eat.

cockatrice meaty 8 33% petrifies when touched or eaten
Medusa meaty 25 100% petrifies when eaten
