If you try to equip armor that is too big for you, the game shouldn’t just tell you “it is too big for you to wear”; instead, it should allow you to wear the armor piece, but it falls off after a turn or two. If the armor is boots, when you move, you should leave the boots on the square where you started.

When undead are destroyed outright by any turn undead effect, they should never leave a corpse.

You should be able to wish for magic items that have a “bane” versus one specific monster type. The weapon deals massive damage to that monster type but has no other advantages.

Uncontrolled teleportitis should count as a minor trouble; a god may decide to fix it by removing it, but only if there are no other troubles. If there are other troubles, teleportitis will not be removed.

Chameleons should only transform into monsters close to them.

The player should have the ability to seduce peaceful characters in a fairly weak, non-magical way (to get better shopkeeper prices and such). This is initiated if you chat to them while wearing no armor. Works best when the target is the same race as you, you are opposite genders, and you have high Charisma. Possibly, seducing a priest in a temple risks the god smiting you.
