Are you meant to be unable to throw the weapon you are wielding?

Yes, that's correct.

I still don't get the recharging at shops mechanic. I just gave a Wand of Frost Bolts and a Wand of Stun Monster to the Magic Shop in hopes that they get recharged. Instead they are now in sale with 0 charges for 800 and 500. How do I, as a player, know which wands and staves get recharged? Could the message when giving to the shop them give some hint or something? Or maybe even have the description say "Can/Can't be recharged at Magic Shop" or something.

This is not the most user-friendly, but if you look in store.txt you will know what they carry/recharge.

:D I deliberately refuse to look at code or config files when reviewing game play. All game play information should be available in the game. Either a) the is no recharging service and the player must stock recharge scrolls or b) there is an easy to use and understandable recharging service. Currently it's neither a) or b). The use of recharging service requires the player to possess exact knowledge on what shops can carry. In my opinion this is something that should be improved to make a great game better.

If I were you I'd demand your money back :D But, yeah, it is confusing and should be improved when possible.

This kind of goes to the Selling option as well.

The problem is that the "recharge" mechanic is a side effect, vs a first class concept. The shop isn't recharging the item, it's simply replenishing it's stock and HAPPENS to recharge the item.

If it were a first class idea, then we'd have a "Recharge" option along with Selling, and Giving.

The selling thing, if the game is not "buying" stuff, then it should simply "refuse" to let you sell things for 0 gold. You can always "give" stuff to the shop, it's just Sell option would remain, but offer a message like "Sorry, I'm not buying things right now."

I don't see the addition of a first class recharge option any time soon. And I don't see "shop rechargability" being a first class property that can be I)npected on an item either.

Right now it's just notes on a sticky for an item taht won't be recharged.

My guideline, if I don't see it in the shop when I first arrive, i assume they won't recharge it.

True that. However the only thing missing is in-game information. No need for actual recharging feature or like. Just in-game information what the shop is able to sell/recharge. There already is a confirmation prompt when giving the item. Maybe the information could be added there. "Give the item for recharging?" or something when it's going to get recharged.

Or when you 'i'nspect the item...

Is it me or the number of chests you find in a game is quite low? It's like you find one every 100 levels or so...
