Well, I guess I'm going to start engraving with my wand to avoid the
1/800 chance that my castle wand explodes on the first zap...(shakes

1) Never use a wand of wishing without first having determined
how many charges are left in it (using a scroll of identity.

2) Is the castle wand of wishing so important. In order to get
to the castle, you need most, if not all, of what you need
to go further anyway. (I've got the castle wand of wishing
in my bag of holding, unused.) If you manage to do the
castle without magic protection, yes, but otherwise, loosing
it is disagreeable, but hardly a reason to abandon.

Yes, I suppose I should start being paranoid about that one too. The
first zap is always fine, though. I was going to get charging since I
didn't yet have it identified, and then write identify with the marker
in my pack.

I had no magic resistance and my armor class was positive 1. I had
absolutely zero chance without the castle wand.

Commiserations, and good writing.

BTW, now I'm happy I recommended engraving instead of zapping on
nethackwiki.com/Wand_of_wishing.

A non-empty/non-cancelled wand can only explode if it's cursed, right?
Probability is then 1 in 100 for a cursed wand.

if (obj->cursed && !rn2(100)) backfire(obj);

An uncursed to be generated wand of wishing will be cursed 1 in 34 cases.
I don't see in the code that the wand-object will be set to cursed/blessed
before the check in blessorcurse(). So it's probably a 1 in 3400 chance
that it explodes? And only if you haven't checked for cursedness, I think.

I've once lost the castle wand due to an electric shock from a chest trap,
where I carried the wand in open inventory instead of putting it in my bag.

In last year's /dev/null tournament, Adeon had to do a game wishless,
because the Castle wand, which was a breakable sort (glass or
crystal), was destroyed in a chest trap explosion. I don't think
there's any way to be 100% paranoid about that, other than playing
Rogue and using the MKoT to untrap the Castle chest before opening it,
as all other untrap sources have a chance of triggering the trap
instead. (Non-Rogues couldn't guarantee a wish to wish up the MKoT in
the first place.)

I'd have said that you had no chance of getting as far as the
castle in that state. (I wouldn't go below around level 10
without a decidedly negative AC.) Generally, if it's a question
of need or making a significant difference, the castle wand
comes too late (in my experience, at least---although I have
been known to reach the castle without magic resistence, in
which case GDSM is quite appreciable).

Well it's not paranoia if the RNG's out to get you...
