Gently discourage Rangers from heavily using daggers by limiting them to Basic skill in dagger.

New artifact dagger that, when thrown, teleports you to wherever it lands. Some attributes it might have:

• If it lands in liquid, you could be teleported to the nearest available land, or to the liquid square, where you promptly fall in, possibly drowning or burning up. A nicer implementation could prevent it from landing in liquid in the first place, teleporting itself elsewhere, since it would be tough to get out.
• If it falls to another level, you levelport to where it falls.
• If a monster somehow eats it, you teleport inside its stomach, killing it (unless it’s capable of engulfing you, in which case you teleport to being engulfed inside it).
• A side proposal is that instead of a dagger, this is an artifact gem.

Parrying Dagger, an artifact dagger which when wielded may automatically counterattack an incoming melee weapon attack, deflecting it so it doesn’t hit and making an attack with itself that does sneak attack damage.

New shop type “thief shop”. Contains blindfolds, lockpicks, thiefstones (if implemented), rogue/pickpocket gloves (if implemented), cloaks and daggers. Something special should happen when you directly steal from a thief shop.

New unaligned artifact dagger Almagest: uses the powers of scrolls to augment itself, and bears a scroll label signifying which scroll ability it is imbued with. Opinions vary on whether this label should be randomly generated by the dagger (and the player may choose to read it, upon which it gives the uncursed scroll effect and disappears for 1000 turns, eventually returning with another label) or whether the label should be deliberately imbued by the player by rubbing it on a scroll. It gains +d4 to damage and +d4 to hit when it has an inscription.

There are additional special effects if the player has formally IDed the scroll whose label is on the dagger:

• Identify: 25% chance of probing
• Light: +d6 to undead, light source
• Enchant weapon: +d4 damage
• Enchant armor: gives 3 points of AC when wielded
• Remove curse: Protects fully from all curses when wielded
• Confuse monster: 25% chance of confusing
• Destroy armor: Ignores enemy armor when calculating to-hit
• Fire: +d8 fire damage
• Food detection: Enemies are much more likely to leave corpses
• Gold detection: Enemies may drop small amounts of gold when killed
• Magic mapping: 5% chance of activating clairvoyance on hit
• Scare monster: 15% chance of scaring on hit
• Teleportation: 10% chance of randomly teleporting on hit
• Amnesia: Extra mindflayer tentacle attack, no effect when read
• Create monster: 5% chance for create familiar effect on hit
• Earth: 5% chance of creating boulder over enemy
• Taming: 5% chance of charm monster effect on hit
• Charging: Does 2x Pw damage and adds it to your own, 5% chance of cancellation
• Genocide: Instakills as Tsurugi, +1 damage
• Stinking cloud: Permanently poisoned
• Punishment: Weighs 100, deals +d12 damage. Autocurses and triples alignment losses.
