An identification-less conduct - you are prohibited from identifying any items. There are three possible implementations of this, in ascending order of strictness:

1. The conduct is broken when you use identification magic to fully identify an item. This does mean it’s a risk to sit on thrones, as the “insight” effect may fully identify your inventory without warning. Use-identifying (e.g. zapping a wand, seeing a bolt of fire, and learning that all wands of that type are wands of fire) is fine.
2. A birth option which shuts off formal identification and use-identification. This would likely just create a lot of tedium, though - the player would be incentivized to type-name object classes that they know for certain as soon as they learn them.
3. A birth option which shuts off formal identification, use-identification, AND the discoveries list (so type-naming is not allowed and you always just see items as their appearance). This nominally removes the tedium of the above approach, but could still result in tedium if the player wants to replicate the discoveries list outside the game.

A “slotlocks” option, taking a string which specifies the inventory letter slots you really do not want newly-acquired items to go into, such as the ones you usually reserve for key pieces of gear.

As an example, if you have OPTIONS=slotlocks:aGHsdy, no inventory items will be placed on any of those letters until they are the only remaining open slots. Once that happens, the first open slot in the string, “a”, will be filled, unless you already put something in that slot, in which case “G” will be attempted, and so on.

Adjusting items to different slots is not affected by slotlocks since it’s presumed you are deliberately putting an item in that slot.

New conduct, permaconflict, which must be enabled by setting an option. If you play the game with this, you constantly generate conflict, which likely makes some aspects of the game much easier and some much more difficult.

Not specified whether the permanent conflict would cause extra hunger like the ring does, or not cause any like artifacts do.

An option that only triggers at the start of the game and adjusts objects into certain letter slots, so players can start the game with items in familiar locations. It would probably be regex-based.

Also mentioned was full lua scripting support similar to what DCSS allows, but that is potentially overkill for this feature.

Add a “randomizer mode”, a non-scoring mode enabled by some option you put in the config file that randomly mutates the stats of each monster – for instance, in one particular game, gnomes could have fewer hit dice and thus lower HP, while soldier ants gain an ice attack.

In the spirit of traditional randomizers, this could also randomize loot, for things like artifacts and invocation items being mixed up and findable in regular chests, monsters generating with and dropping gear they shouldn’t have, etc.

Something to prevent autounlock from automatically forcing a chest you want to open. This probably takes the form of a new option, either an “autoforce” boolean option or a new paranoid confirmation flag which would add a prompt (or turn the existing prompt into a “yes” confirmation) before you force a chest with autounlock.

An option that automatically dismisses the “Where do you want to be teleported?” prompt if you have both teleportitis and teleport control.

An option to set the name of your juice potions, separate from the fruit, so that you can have your fruit being e.g. “pizza” without potions of juice tasting like “pizza juice”. If this option is unset, the juice name defaults to the configured fruit name.

A paranoid cannibalism option, which prompts you to confirm when you are about to eat something that would be considered cannibalism (including dogs and cats if they would incur the same penalties).

Establish two subclasses or sub-roles of Monk: weaponless (traditional) monk and weapon-using monk.

• The choice can be either configured with a game option or chosen in initial character setup.
• Using weapons when you have chosen to be weaponless, or vice versa, you take alignment penalties.
• Weapons monks could start with shuriken and have much poorer maximum energy growth per level.

An option to have your starting pet assigned a random name. The name pool would probably come from a hardcoded list (or even a text file like engrave.txt).

Add an option that forces the hero to be rendered even when invisible and unable to see invisible; terminals may not reliably display a distinct cursor that allows the player to tell where they are.

New option ‘spoilers’ or ‘spoiled’. When on, the game is free to enable a bunch of quality-of-life enhancements that spoil various parts of the game, such as auto-identifying wands based on their messages and sorting items into price tiers from price identification. Defaults to off.

An option that disables special level flipping.

Add an option that makes you begin the game with all weapons dropped on the floor. This is to prevent you ever wielding a weapon so you can’t break weaponless.

A ‘spoilers’ option that toggles on certain interface features that assume a player is spoiled. Defaults to off. An example of such a feature is FIQHack’s automatic identification of a wand of teleportation when the player makes an engraving vanish with it and has already identified the other wands that do so.

Create an option that allows the player to specify a single particular set of potion types, then provide a fairly accessible thing in the game that allows potions to be distinguished as either in that set or not in that set.

An option that changes all the game’s messages to their hallucinatory counterparts, without requiring the player to be hallucinating, and without affecting the symbols displayed on the map. Messages that mention monsters turn them into fake hallucinatory monsters, but farlook will represent them accurately.

Rather than marathon mode using a fixed value of 999 HP, you can set an option to control how much HP is used. (If the option is not set, it will default to 999). The value should appear in both the xlogfile (so that tournaments can set some threshold of HP beyond which the game doesn’t count) and dumplogs.

Extend the warning scale up to level 9 (and possibly down to level 0) to offer more granular information on warning threats. However, provide an option to keep the scale at its old 1-5 for players who want to assign monsters to the 6 through 9 glyphs.

Add a new option that controls whether autopickup functions in shops. If it is on AND regular autopickup is on, items will be autopickedup in shops; if either of the two are off, they won’t.

Option to configure your character to be nearsighted, which prevents you from seeing things more than a few spaces away from you unless you’re wearing lenses. You can also be farsighted, which means you can’t read scrolls or spellbook unless you’re wearing lenses.

Your discoveries list is presented as a menu rather than a fixed list of every single thing you have discovered. The menu contains the subcategories that the current long list is organized into (weapons, scrolls, gems etc), which will let you view that subset of your discoveries. There’s also an option provided to view all the discoveries at once if you want to view that. Possibly this feature should be controlled by an option.

Option to invert the colors of liquids, so the dominant color of the character glyph is the liquid color.

Paranoid eat option, which makes you have to type out “yes” for “Continue eating?”

An option to disable Japanese item naming.

Option to bring up the prompt to type-name an item any time it would normally be prompted, even if the object is already type-named. The example given is that if you price-id an object and then later see a monster use it, you then have the option to add this new information immediately.

Allow configuration of a list of monsters that the player should be prompted to confirm fighting before automatically attacking by moving into them. Fighting with F bypasses this check.

Also, possibly add an option to make this behavior happen for any monster.

A set of options (similar in structure to the paranoid options) that manages triggers that you want to interrupt you. Examples of triggers: a monster attacks, you teleport due to teleportitis, a monster comes within sight, a monster comes adjacent to you.

Separate command to pick up an item and put it into a bag immediately after, in 1 turn. Or an option that changes pickup behavior to this effect.

If you happen to get teleported while you are _ traveling and you have teleport control, the cursor is automatically placed on where you wanted to travel to. (It doesn’t automatically teleport you there - you are still able to move the cursor around before doing the teleport.)

Possibly, add an option to toggle this behavior off, though it’s hard to imagine why someone wouldn’t want it.

Booze is a customizeable name in the options like fruit/slime mold.

Option to make the confirmation letter “Y” instead of “y” so that you don’t accidentally hit people when moving in the “y” direction.

Provide an option to label branches with the branch name instead of using “Dlvl:” all the time. Also allow it to be shortened to “DL”, with no colon, for those who want extra space in the status bar.

Add an option to re-enable displaying statues as `, rather than their monster symbol.

“streak_mode” option. Only allows one saved game at a time.

Pacifist option, which suppresses the normal bump-to-attack mechanic. (You can still attack with the F command.)

Interface option to shorten “blessed”, “uncursed” and “cursed” to three letters so that you get more use out of the inventory sidebar.
