D2 Staffmod 的选择

(Hammerman 提供)

一. 什么是 Staffmod

    在某些类型的装备上, 尤其是角色专用装备上, 除了词缀赋予的属性外,
还具有加某项技能的属性, 称为 "Staffmod". 例如, 一个白色的女巫手杖
上可能会有 "+3 blizzard (Sorceress only)". Staffmod 不出现于暗金装
备上.


二. 哪些物品具有 Staffmod

    部分 刺客爪(Katar)  : 加刺客技能,   base_id = 251
    法杖(Wand)          : 加男巫技能,   base_id =  66
    男巫盾(Shunken Head): 加男巫技能,   base_id =  66
    野蛮人头盔(Bar Helm): 加野蛮人技能, base_id = 126
    骑士权杖(Scepter)   : 加圣骑士技能, base_id =  96
    女巫杖(Staff, Orb)  : 加女巫技能,   base_id =  36
    德鲁依头盔(Pelt)    : 加德鲁依技能, base_id = 221

    base_id 在后面选择技能时会用到.
    并非所有的刺客爪子都有 Staffmod, 仅以下可以:
      Battle Cestus
      Feral Claws
      Greater Claws
      Greater Talons
      Hand Scythe
      Runic Talons
      Scissors Quhab
      Scissors Suwayyah
      Suwayyah
      War Fist
      Wrist Sword


三. 具体技能的选择方法

1. 决定技能的个数

    首先系统随机选取一个 0 ~ 99 之间的整数, 记为 m ;
如果该物品是 imbue 得到的, 则 m 要加上物品的 Ilvl.

    若 m >= 90, 则出现三个技能;
    若 70 <= m <= 89, 则出现二个技能;
    若 30 <= m <= 69, 则出现一个技能.

(关于 Ilvl 请看 这里.)

2. 选择技能偏移量(shift_id)

    shift_id 仅与物品的 Ilvl 有关:
=====================
  Ilvl     shift_id
---------------------
  1 - 11      1
 12 - 18      2
 19 - 24      3
 25 - 36      4
 37 - 99      5
=====================

3. 修正 shift_id

    shift_id 保持不变的几率为 50% ;
    shift_id +1 的几率为 20% ;
    shift_id -1 的几率为 10% ;
    shift_id -2 的几率为 20% .

    如果该物品是低品质的(low quality, damaged, cracked, crude),
则 shift_id 不超过 4 .

4. 选择技能(skill_id)

    选择技能的次数由第1步中决定的技能个数来决定. 每次技能选择
的方法如下:
    首先, 系统从 0 ~ 4 之间随机选一个整数, 记为 n ;
    然后选择技能ID:
        skill_id = base_id + 5 * shift_id - 5 + n ;
若此 skill_id 在前面的选择过程中已经被选中, 或者 skill_id = 73,
则要重新选择 skill_id, 在这一步骤上, Hammerman 和 Jarulf 的意见
不同:
    Hammerman: 在已经选择的 skill_id 上再加上 0 ~ 4 之间的随机
        整数;
    Jarulf: 重新选择 0 ~4 之间的随机整数 n, 再计算
        skill_id = base_id + 5 * shift_id - 5 + n .
    个角色的 base_id 见前. 各个技能的 skill_id 见本文末尾.

四. 决定技能的等级

    对每个选中的技能分别决定其等级. 方法如下:

    随机选取 0 ~ 99 之间的整数, 记为 x ; 若该物品是 imbue 来的, 
则 x 要加上 ilvl/2 ;

    若 x >= 90, 则技能等级为 +3 ;
    若 60 <= x < 90, 则技能等级为 +2 ;
    若 x < 60, 则技能等级为 +1 .


五. 注释

    base_id 实际上就是该角色的技能中 skill_id 最小的那个技能的ID.
    注意, skill_id 是不会超出该人物的技能之外的. skill_id 不能选
73 表明 Wand 上永远不会出现 Poison Dagger 这个技能. 
    在 Hammerman 的原贴里, 用 "skill_id" 来表示 "shift_id", 用
"id" 来表示 "skill_id", 我为了意义上的清晰而做了更改.
