Wands are listed above by increasing price, then alphabetically.  The
COST field denotes the base price of each item.  WGT specifies the weight
(100 zorkmids weighs 1).

Wands comprise 4% of all randomly-generated items in the main dungeon,
6% in containers, 5% on the Rogue level, and 8% in hell.  PROB is
the relative probability of each subtype.  They appear 1/34 cursed,
16/17 uncursed, and 1/34 blessed.

The CHG field specifies the maximum number of charges that a wand
normally has.  An exclamation (!) denotes that a wand of wishing may only
be recharged once.  Wands of wishing start with 1 to 3 charges; otherwise,
the wand starts with a number of charges at most 4 less than its maximum.

Each time you (z)ap or (E)ngrave with a wand, you use one charge.  A wand
with zero charges left has a 1 in 121 chance of wresting a last charge
and then turning to dust each time it is zapped (this won't happen if the
wand was cancelled but not recharged).  Cancelling a wand will make it
uncursed and (except for wands of cancellation) it will get zero charges.

Wands may be recharged by scrolls of charging or by the Platinum Yendorian
Express Card.  Previously-recharged wands have a chance of exploding (up
to a maximum of 100% for a 7:x wand or a wand of wishing); see scrl-343.txt.
A cursed scroll will have no effect on a blessed wand or a wand with no
charges; otherwise, "Your <wand> vibrates briefly" and it gets zero charges.
An uncursed scroll will bring the number of charges to a random number from
1 to a random number between 5 and the maximum charges shown above (or for
a wand of wishing a random number from 1 to 3); a blessed scroll will bring
the number of charges in the wand to a random number from 5 to the maximum
charges shown above, or for a wand of wishing to three charges.  If it
already has that number of charges, it gains one more charge.  A wand of
wishing charged beyond three charges will explode.
"Your <wand> <glows vibrates=""> briefly." if the new enchantment is below the
maximum; "Your <wand> <glows blue="" vibrates=""> for a moment." otherwise.

The TYPE of wand denotes the behavior when it is zapped.  NODIR wands do
not ask for a direction.  BEAM wands ask for a direction, but do not show
a visibly animated effect when zapped.  RAY wands produce a ray which is
animated on the screen; if you are unblind when you zap the wand, you
will also identify that type of wand.

The appearances of wands are randomized from the following descriptions:
    glass       balsa       crystal     maple       pine
    oak         ebony       marble      tin         brass
    copper      silver      platinum    iridium     zinc
    aluminum    uranium     iron        steel       hexagonal
    short       runed       long        curved      forked
    spiked      jeweled

Zapping wands
~~~~~~~~~~~~~
Nondirectional wands will be identified if you saw their effect (e.g., you
found a secret door with a wand of secret door detection).  If the wand
produces a visible ray or beam, you will identify the wand if you were
unblind.  The range of a RAY will be 7 to 13 squares; this range may be
lessened by the ray causing effects or bouncing.  Zapping a RAY wand
upwards or downwards is equivalent to restricting the ray to a range of 1.
BEAM wands have a range of 6 to 13 (other than digging), which can
similarly be lessened, and will not bounce; they will be identified if you
observe an effect caused by them.

Cursed wands have a 1% chance of exploding when zapped; this does 1 to
6 points of damage for each charge in the wand, plus an additional 2
to 12 points of damage, and abuses your strength.

Monsters are not angered by wands of digging, locking, nothing, opening,
probing, or undead turning (if not undead and none of their inventory was
affected); being zapped with (or missed by) other wands will cause peaceful
monsters to become hostile if you were the zapper.

    Doors and walls count as 3 spaces; stone as two.  If not in a

Engraving with wands
~~~~~~~~~~~~~~~~~~~~
Use the (E)ngrave command to engrave with a wand.  It will use one charge
(possibly wresting the last) from the wand.  Depending on the type of the
wand, you can get one of the messages below if you are unblinded, not
levitating, and over a writable floor.  Some messages are the same for
different types of wands, some messages require an engraving already on
that square, and some wands will not provide any means of identification
this way.  Nondirectional wands will act as if they were zapped.  If you
didn't wrest the last charge from the wand, you can write a message in
the dust (or engrave if specified below).  These messages provide (perhaps
in combination with judicious zapping) a safe method of identifying many
wands.
