When you drop a wand of striking while levitating, it should “strike” the floor rather than the usual “hit” the floor.

For TDTTOE, you only receive a “telepathic” message from your quest leader if you actually have telepathy. Otherwise, you merely “sense” the message.

Add a TDTTOE message about swinging your dead cat if you start hitting things with a wielded cat corpse. Also have a separate message “There isn’t enough room to swing your dead cat” if there are 4 or more walls adjacent to you.

Give a YAFM if you would “sink like a rock” while currently turning to stone, or polymorphed into a stone monster (gargoyles, earth elemental, stone golem).

• if petrifying: “You sink like a rock, because you are becoming one.”
• if a stone monster: “You sink like a rock, because you are one.”

Delicatessen shopkeepers chide you if you eat something while in their shop that doesn’t belong to them and that you didn’t buy from them. “Buy something or get out!”

Ravens flee from straw golems, who are basically scarecrows.

If you manage to get an aligned priest to wear a helm of opposite alignment, he becomes a priest of a different god. (Not defined what this should do to Moloch priests; maybe their heads explode?)

Cavemen, Barbarians, and orcish players don’t get the message “An urge to take a bath overwhelms you” from fountains.

TDTTOE: If it’s possible to fooproof arbitrary items, fireproof candles are unlightable.

TDTTOE: Skeletons use gendered pronouns if and only if the player is an Archeologist (and therefore used to analyzing bones).

If you press Escape while being grabbed by a monster, at a time when you could normally enter input (so not in the middle of messages or in a prompt), you get the message that says “You cannot escape from the [monster]!”

Quantum mechanics’ hits toggle your speed instead of teleporting you if you have teleport control. (You already know your position, so your velocity must become uncertain.)

The Norn and Valkyrie quest friendlies have different messages if you talk to them after having been changed into a man.
