Problem
Wishing for certain things has a variety of strange/unrealistic (for lack of a better word) reactions.

(1) Wished-for ratling guardians are as immobile as those in the HMV, and respond with the same message about guarding the city when 'C'hatted with.
(2) Wished-for non-hostile ancient karmic wyrms are immobile, think they are Sharad-Waador and ask the PC to "Stand on the stairs... then we'll talk." when 'C'hatted with.
(3) Wishing for a monster that can ignore walls if surrounded by diggable walls and two doors/monsters still gives the "For some seconds a ghostly figure..." message (thrice), when it should be able to spawn in a wall.
(4) If the player uses a wand of wishing or gets a wish from a pool, and then makes a wish that doesn't match any item or abstract concept in the game (even after spell checking), absolutely no response is given. It should say "Nothing happens." like when one casts the Wish spell or gets it from a wand of wonder.

Note this excerpt from the changelog: "When you failed to wish for an item with a wand of wishing, no text at all was displayed."

(5) Using a blessed ring of djinni summoning can give two wishes: a skill dice increase, and something else of the player's choice. This depends on how trained the wished-for skill is. A full explanation is available here. Similarly, using wands of wishing or the Wish spell will yield no message whatsoever, while still increasing the skill's dice. In both cases it should give "you better understand the -foo- skill" (or whatever the exact words are), and if it's a RoDS, the djinni shouldn't say that's a foolish wish and give you a refund.
(6) Wishing for a greater moloch that appears in an altar square doesn't immediately break the altar.
(7) When a wish increases your proficiency with a skill (i.e. you wish for a skill you already have), it also reduces your dice for it as if it was a regular skill advancement.
(8) The player can't wish for "heavy cudgel(s)" or "black tomes", or misspell a wish for "clothes", because the game thinks they're asking for artifacts.
