Various effects for armor pieces based on their randomized description:

• Buckled boots and old gloves: cost (and sell for) twice as much in a shop.
• Hiking boots: prompt before walking into known pits or holes.
• Mud boots: autocurse when worn.
• Padded gloves and visored helmet: +1 to AC.
• Tattered cape: -1 to Charisma.
• Ornamental cope: +1 to Charisma.
• Opera cloak: some sort of bonus when using musical instruments.
• Plumed helmet: +1 to Charisma, -1 to Dexterity (or have these adjustments multiplied by its enchantment).

Attempting to pick a lock with low Dexterity has a chance of jamming the lock, making it impossible to pick or use a key on. Opening magic and forcing the lock can still be used.

Quaffing a potion of speed should exercise dexterity. Possibly only if it is non-cursed.

Rolling boulder trap hit chance and damage is based on dexterity and not AC, for how much you can jump out of the way. Only high dexterity will allow you to dodge the boulder entirely.

Stealing gloves (also possibly named “rogues gloves” or “gauntlets of thievery”). 0 base AC, and Rogues begin the game wearing a pair. When you hit a monster barehanded while wearing them, you deal no damage (and don’t train bare handed combat skill) but you get a Dex-versus-monster-AC chance of stealing a random non-equipped item or some gold out of their inventory. You can also attack a peaceful monster with them to attempt to steal something; in addition to the Dex-vs-AC roll, this requires passing both another Dex check and a Cha check for them not to notice. If the Dex check fails, you don’t steal anything successfully; if the Cha check fails, they notice (waking up if asleep) and get mad. If the stolen item is currently equipped, there’s no Cha check; the monster just gets alerted and angry.

When you step onto a pit or hole, your chance of falling in is based on your Dexterity rather than being the usual flat 20% chance for traps.

Boost healers’ starting Dexterity; they should be better at delicate surgical procedures than the minimum Dx:7 implies.

You have a small Dexterity-based chance of catching a potion thrown at you instead of having it break on you (this chance is zero if you cannot see the thrower.)

Additional temporary effects accompany drinking a potion of booze. The effects wear off when the confusion does (so if you extend it by, say, drinking a potion of confusion, the effects are prolonged). There is consensus that there should be both positive and negative effects; all of the following have been proposed:

• A damage bonus, or even double damage
• Temporary HP
• An accuracy penalty (or a Dexterity penalty)
• Slight reduction of speed
• Temporary cold resistance (debatable; if possible it should probably make you not feel cold attacks but still take regular damage from them)
• Attacking an enemy makes you automatically keep fighting it until one of you is dead
• Monsters are treated as having higher charisma (currently no monsters are treated as having charisma at all, but this could also hurt or nullify your ability to refuse a foocubus removing your clothes)
• You may pass out when the confusion ends, and end up with a hangover when you wake up. (Not described what the effects of a hangover would be). You may also find yourself suddenly on a different level when you wake up.
• You are protected from gaze attacks due to not being able to focus enough to meet someone’s gaze.
• If you’re a dwarf, the effects get magnified
• If there is any such thing as a player-is-scared effect, it is canceled when you drink the booze and blocked while you’re under the influence. This goes for however long the confusion persists, so you can extend it by drinking potions of confusion if you want.
• Any AC from your armor is nullified (this would also contribute to monk “drunken boxing” proposals, since monks don’t usually have as much armor AC)

Condensing all of NetHack’s poison mechanics into one unified mechanic:

• Dexterity and Constitution poisons are removed. Quasits (the only AD_DRDX attack) might still directly harm Dex, but it’s no longer flavored as poison. Rabid rats (the only AD_DRCO attack) don’t cause poison, they cause disease, which hits Constitution. Poison will now only affect Strength.
• Poison is now implemented as a timing-out trinsic. The amount of Str loss is a direct function of how much timeout is left, so Str will gradually recover as the poison goes away.
• Passing Con saving throws could give small bonuses to decreasing the timeout faster than normal.
• While poisoned, HP regeneration is either impeded or stopped entirely, or else the player’s HP is damaged every turn, or every several turns.
• It could also heavily abuse Str while it lasted instead of being directly tied to Str.

Determining whether you escape or dodge trap effects should be based on stats like Dexterity and maybe role and XL, rather than Luck.

You can loot trees to get less fruit than you might by kicking it, but the chance of getting bees is much reduced. This might fail, in which case you might fall out of the tree and abuse Dexterity or something similar. If you are polymorphed into a Y, it has a 100% chance of success; if a human or elf, probably 80%; if an orc, 40-50%; if a gnome or a dwarf, 1-5%.
