许愿魔杖（wand of wishing）是NetHack中的一种魔杖。
Contents
生成
许愿魔杖在随机生成魔杖中占比1⁄200（0.5%）。
许愿魔杖不会出现在角色的起始物品中[1]。若玩家在探索模式下开始游戏，则在游戏开始时会额外获得一支未诅咒，有3点充能的许愿魔杖[2][3]。
在城堡关卡的塔楼结构中，必定会生成一个装有一支许愿魔杖的箱子。
和其他魔杖不同，许愿魔杖随机生成时的充能数为1～3点[4]。
玩家无法通过变形将其他魔杖转化成许愿魔杖。
若通过许愿获取许愿魔杖，则有9⁄10的概率获得一支(1:-1)的许愿魔杖（即已经充能过一次且被取消，玩家将不能从此魔杖获得任何许愿），1⁄10的概率获得一支(1:0)的许愿魔杖（即已经充能过一次且已耗尽充能，玩家只能通过攫取来从此魔杖获取最后一次许愿）。

根据commit 615edb1c，现在许愿魔杖生成时充能数必定为1。描述
挥动有充能的许愿魔杖，或用有充能的许愿魔杖刻写时，只要玩家的幸运值不是负数，魔杖便会自动鉴定并给予玩家一次许愿[5][6][7]。如果玩家在幸运值为负数的情况下挥动许愿魔杖，则魔杖有−L5（L为玩家的幸运值，计算结果最大为1）的概率不发动效果[8]。
许愿魔杖的充能数上限为3，且至多只能被充能一次[9]。若在许愿魔杖的充能计数为1的情况下继续对其充能，或是尝试将魔杖的充能提升到高于3的数值，魔杖会爆炸并造成2d12点伤害[10][11][12]。
折断许愿魔杖没有效果。
怪物不会使用许愿魔杖。

根据commit 615edb1c，现在为许愿魔杖进行充能只能补充1点充能值。策略
如果你在商店里发现了基础价为500 zm的魔杖，它一定是许愿魔杖或死亡魔杖。两种魔杖都值得购买，即使你可能需要花费大量时间进行信用点复制或收集垃圾卖钱。如果你没有宠物，无法进行信用点复制，你可以许愿获取金币，具体细节可参阅主条目中的前期的许愿魔杖一节。
充能
如果你还没有充能来源，你从许愿魔杖获得的第一个许愿就应该用来获取它。一般来说，你可以许愿2～3张受祝福的充能卷轴。如果你已经鉴定了充能卷轴，则最好许愿一支魔笔来写更多的充能卷轴。高幸运值的巫师可以以极高的成功率写出未发现的卷轴，因此即使没鉴定充能卷轴也可以直接许愿魔笔来写。
另一种可以提供充能的来源是岩德至尊白金卡，不过如果你不挑战文盲行为，一般不推荐许愿白金卡作为许愿魔杖的充能道具，因为非游客的角色用白金卡只能发挥出未诅咒的充能卷轴的效果，这样就无法确保魔杖会被充满能量，而游客无法许愿获取自身的任务奖励。由于游客完成任务会获得岩德至尊白金卡作为奖励，因此游客可以考虑不许愿充能来源，而是等到完成任务后再为许愿魔杖充能。
最大化许愿次数
许愿前最好先确保自己的幸运值不是负数，且魔杖不是被诅咒的，以防浪费珍贵的许愿机会[13]。
你可以通过以下方法将你从一支许愿魔杖中获得的许愿次数最大化：
- 挥动或刻写，直到魔杖的充能成为(0:0)。
- 使用受祝福的来源为魔杖充能，这样魔杖的充能会变为(1:3)，注意未诅咒的充能来源只会将魔杖的充能变为(1:d3)。
- 挥动或刻写，直到魔杖的充能成为(1:0)。
- 反复挥动或刻写，直到魔杖的最后一点能量被攫取。
如果你担心在以上过程中提前触发攫取效果，你可以考虑在使用魔杖前先鉴定它还有多少充能数，然后再挥动或刻写。

现在许愿魔杖生成时拥有的充能数大大减少了，因此不推荐优先用许愿魔杖获取充能源。历史
许愿魔杖最初于Hack 1.0加入游戏。
在NetHack 1.3d和NetHack 1.4f版本中，地牢深处生成的每个迷宫楼层的某个随机位置都会生成一支放置在一块巨型岩石下方的许愿魔杖[14][15]。在NetHack 2.2a和2.3e中，美杜莎楼层下方的第一个迷宫楼层仍然会必定生成一支许愿魔杖，但其他迷宫关卡生成许愿魔杖的概率降到了1⁄10[16][17]。
Variants

Many NetHack variants alter wands of wishing to provide fewer wishes per wand and spread those wishes out across the later parts of the game. Some variants may remove the wand entirely and replace them with different wish sources.
UnNetHack
In UnNetHack, wands of wishing are generated as being recharged once (1:x) and thus cannot be charged again. This reduces the amount of wishes that can be obtained from the wand to 1-4, counting the potential to wrest a last wish: wands with zero charges in UnNetHack can only be zapped once before they turn to dust, but in exchange they have a higher chance of successfully wresting a final charge—the chance is 1⁄5 for blessed wands, 1⁄6 for uncursed wands and 1⁄7 for cursed wands.
Additionally, wands of wishing are the only source available for wishes that can create magical items: the shield of reflection is non-magical in UnNetHack so that a source of reflection remains available from other wish sources as well.
dNetHack
In dNetHack, notdNetHack and notnotdNetHack, wands of wishing have been removed and replaced with rings of wishes and candles of invocation.
NetHack Fourk
In NetHack Fourk, random wands of wishing are generated as being recharged once, similar to UnNetHack, but wresting is made easier compared to NetHack and still allows multiple attempts. To compensate for this, Fourk adds a guranteed scroll of wishing to each of Orcus-town, the top floor of Vlad's Tower, and the top floor of the Wizard's Tower.
xNetHack
In xNetHack, wands of wishing cannot be recharged, though their state is displayed as (0:x) rather than (1:x). When they reach 0 charges, they immediately turn to dust, so wresting them is impossible.
They are no longer generated randomly; instead, statically-placed wands of wishing are found in the Castle, the top floor of Vlad's Tower, the Fake Wizard's Tower that lacks the magic portal, the top floor of the real Wizard's Tower, and the northeastern room of Moloch's Sanctum. All of these are generated with 1 charge, except the Castle's, which has 2.
SpliceHack
In SpliceHack, wands of wishing are handled the same as in xNetHack, with several individual wands scattered across Gehennom, although the wand found in Vlad's Castle is cursed.
EvilHack
In EvilHack, wands of wishing are very rare to find randomly, and all wands are always generated as charged once already (1:x).
As of version 0.9.0, there are three guaranteed wands of wishing in the game:
- The Castle's wand is the first wand, and has a fixed two charges (1:2).
- The second wand is obtained by destroying Vecna, and appears in a similar manner to The Eye of Vecna or The Hand of Vecna—its number of charges will be random (1:x), and it will always generate as erosion-proof in case Vecna is destroyed over lava.
- The third and final wand can be found in the crystal chest in the top level of the Wizard's tower, and the chest is placed where the Wizard of Yendor himself is generated at level creation. This wand always has a singular charge (1:1).
