## 8. Conduct

s if winning NetHack were not difficult enough, certain players seek to challenge themselves by imposing restrictions on the way they play the game. The game automatically tracks some of these challenges, which can be checked at any time with the #conduct command or at the end of the game. When you perform an action which breaks a challenge, it will no longer be listed. This gives players extra ``bragging rights'' for winning the game with these challenges. Note that it is perfectly acceptable to win the game without resorting to these restrictions and that it is unusual for players to adhere to challenges the first time they win the game.

Several of the challenges are related to eating behavior. The most difficult of these is the foodless challenge. Although creatures can survive long periods of time without food, there is a physiological need for water; thus there is no restriction on drinking beverages, even if they provide some minor food benefits. Calling upon your god for help with starvation does not violate any food challenges either.

A strict vegan diet is one which avoids any food derived from animals. The primary source of nutrition is fruits and vegetables. The corpses and tins of blobs (`b'), jellies (`j'), and fungi (`F') are also considered to be vegetable matter. Certain human food is prepared without animal products; namely, lembas wafers, cram rations, food rations (gunyoki), K-rations, and C-rations. Metal or another normally indigestible material eaten while polymorphed into a creature that can digest it is also considered vegan food. Note however that eating such items still counts against foodless conduct.

Vegetarians do not eat animals; however, they are less selective about eating animal byproducts than vegans. In addition to the vegan items listed above, they may eat any kind of pudding (`P') other than the black puddings, eggs and food made from eggs (fortune cookies and pancakes), food made with milk (cream pies and candy bars), and lumps of royal jelly. Monks are expected to observe a vegetarian diet.

Eating any kind of meat violates the vegetarian, vegan, and foodless conducts. This includes tripe rations, the corpses or tins of any monsters not mentioned above, and the various other chunks of meat found in the dungeon. Swallowing and digesting a monster while polymorphed is treated as if you ate the creature's corpse. Eating leather, dragon hide, or bone items while polymorphed into a creature that can digest it, or eating monster brains while polymorphed into a (master) mind flayer, is considered eating an animal, although wax is only an animal byproduct.

Regardless of conduct, there will be some items which are indigestible, and others which are hazardous to eat. Using a swallow-and-digest attack against a monster is equivalent to eating the monster's corpse. Please note that the term ``vegan'' is used here only in the context of diet. You are still free to choose not to use or wear items derived from animals (e.g. leather, dragon hide, bone, horns, coral), but the game will not keep track of this for you. Also note that ``milky'' potions may be a translucent white, but they do not contain milk, so they are compatible with a vegan diet. Slime molds or player-defined ``fruits'', although they could be anything from ``cherries'' to ``pork chops'', are also assumed to be vegan.

An atheist is one who rejects religion. This means that you cannot #pray, #offer sacrifices to any god, #turn undead, or #chat with a priest. Particularly selective readers may argue that playing Monk or Priest characters should violate this conduct; that is a choice left to the player. Offering the Amulet of Yendor to your god is necessary to win the game and is not counted against this conduct. You are also not penalized for being spoken to by an angry god, priest(ess), or other religious figure; a true atheist would hear the words but attach no special meaning to them.

Most players fight with a wielded weapon (or tool intended to be wielded as a weapon). Another challenge is to win the game without using such a wielded weapon. You are still permitted to throw, fire, and kick weapons; use a wand, spell, or other type of item; or fight with your hands and feet.

In NetHack, a pacifist refuses to cause the death of any other monster (i.e. if you would get experience for the death). This is a particularly difficult challenge, although it is still possible to gain experience by other means.

An illiterate character cannot read or write. This includes reading a scroll, spellbook, fortune cookie message, or t-shirt; writing a scroll; or making an engraving of anything other than a single ``x'' (the traditional signature of an illiterate person). Reading an engraving, or any item that is absolutely necessary to win the game, is not counted against this conduct. The identity of scrolls and spellbooks (and knowledge of spells) in your starting inventory is assumed to be learned from your teachers prior to the start of the game and isn't counted.

There are several other minor challenges. It is possible to eliminate a species of monsters by genocide; playing without this feature is considered a challenge. You can change the form of any object into another object of the same type (``polypiling'') or the form of your own body into another creature (``polyself'') by wand, spell, or potion of polymorph; avoiding these effects are each considered challenges. Finally, you may sometimes receive wishes; a game without an attempt to wish for an object is a challenge, as is a game without wishing for an artifact (even if the artifact immediately disappears).
