常规
- O类技能是一种没有特定类别修饰的技能，比如“+X至战斗体制”或者“+X至热诚”。作用在特定修饰的技能上时最多+3技能等级。举个栗子，“残暴”符文之语圣骑士使用时只+3级热诚而不是+12-14变量列表上的技能等级。 这是D2常规机制。
近战溅射
近战溅射是瞬间范围性伤害（AoE), 并且不存在NHD(Next Hit Delay), 对目标周围360度范围内的所有敌人造成伤害, 但主目标不受到溅射伤害
溅射伤害也是基于敌人的抗性来计算的，粉碎性打击，撕裂伤口这类几率施加的效果也会计算在在每次的溅射攻击中。
这些都包括在溅射中:
- 技能伤害
- 转换伤害 (如：专心)
- 普通攻击伤害 (当你选择基础攻击作为你的技能时，你看到的数值)
- 加元素和物理伤害的护身符或装备
- 致命打击和双倍打击 (仍然只适用于物理伤害)
- 生命和法力吸取 (1/2效果, 只适用于物理攻击)
- 粉碎性打击(CB)
这些都不包括在溅射中:
- 远程伤害 (比如威力一击的新星)
- 击晕
- 击退
- 任何其他“击中”效果 Any other on-hit effects
近战溅射伤害举例
我们来看几个例子. 首先, 先看一下亚马逊:
- 闪电攻击Lightning Strike有1-10000 闪电伤害和1-10000 连锁闪电伤害
- 普通攻击伤害 1000-5000 (900-4900是物理伤害)
最终溅射伤害为1001-15000
如果出现暴击那么溅射的最终伤害为1451-17450
1-10000的连锁闪电伤害不适用
再来看看野蛮人:
- 专心 (300% ED, 50% 转换)
- 普通攻击伤害 1000-5000 (其中900-4900是物理伤害)
首先物理伤害部分被专心的ED%加成由900-4900变成1800-9800
然后50% 的物理伤害转化为魔法伤害
最终溅射伤害为 1900-9900 [100-100元素伤害 + 900-4900物理伤害 + 900-4900魔法伤害]
如果出现暴击那么溅射的最终伤害为 2800-14800
溅射半径
玩家的基础近战溅射半径为 5 格（3.33 码），但半径可以通过某些技能和物品来提升。每增加 20% 的“溅射半径”，飞溅半径将增加 1 格（0.66 码）。
| Increased Splash Radius | 0 | 20 | 40 | 60 |
|---|---|---|---|---|
| 格 | 5 | 6 | 7 | 8 |
| 半径 (码) | 3.33 | 4 | 4.66 | 5.33 |
还有一些其他的东西有近战溅射.这些都是静态的，不能增加.
- "溅射" T图词缀: 溅射半径 5 格 (3.33 码)
- 石魔: 溅射半径 4 格 (2.66 码)
- 骷髅: 溅射半径 3 格 (2 码)
- 狼: 溅射半径 2 格 (1.33 码)
近战溅射和远程武器
一些手套(柏克之手, 血拳, 碎钢) 他们有近战溅射属性，可以用来给远程武器，如弓和弩实现近战溅射.
这允许变形人物使用远程武器代替近战武器，同时还能获得近战飞溅的好处.
这意味着远程攻击(比如用弓射击)不会有溅射伤害。近战溅射通常仅限于近战攻击.
致命伤害
暴击伤害被重新平衡，通过使致命攻击的威力与其他物品属性更具可比性来改善物品化，其他暴击几率的来源也以同样的方式发生了变化。技能被重新平衡，增加了额外的伤害，以弥补这种差异。
每种暴击的上限为75%而不是100%，同时暴击物理伤害倍率为1.5倍而不是2倍.
暴击有3种不同的来源:
最终暴击几率: 1 - ((1 - DS) * (1 - CS) * (1 - WM)) (四舍五入到最接近的百分比)
- 以亚马逊为例，
- 50% DS 暴击 来自装备
- 50% CS 暴击 来自双倍打击
- 1 - ((1 - 0.50) * (1 - 0.50) * (1 - 0)) = 75% 几率暴击
- 另一中情况:
- 40% DS 暴击 来自装备
- 65% CS 暴击 来自双倍打击
- 30% WM 暴击 来自标枪和矛精通
- 1 - ((1 - 0.40) * (1 - 0.65) * (1 - 0.30)) = 85% 几率暴击
理论最大暴击几率为95% (75% DS, 75% CS, 35% WM)
生命和法力偷取
吸取降低
近战吸取降低
- 溅射攻击: 1/2 [生命/法力]
- 范围攻击: 1/2 [生命/法力]
技能吸取降低
- 刀刃之盾: 1/2 [生命/法力]
- 跳跃攻击: 1/3 [生命]
难度吸取降低
- 普通: N/A
- 噩梦: 1/2 [生命/法力]
- 地狱: 1/3 [生命/法力]
区域吸取降低
- PvP 地图: set leech to 0% [生命/法力]
吸取公式
吸取的 生命/法力 = [[[吸取 * 近战吸取降低 * 技能吸取降低] * 64 * 难度吸取降低] * 物理伤害 * 怪物吸取抗性（drain_effectiveness） / 64 / 100]
Note: Bracketed values are rounded down
举个例子, 7%生命吸取属性，野蛮人使用5K面板的跳跃攻击技能打地狱难度母牛之王:
- [[[7 * 1/2 * 1/3] * 64 * 1/3] * 5000 * 0.2 / 64 / 100]
- [[1 * 64 * 1/3] * 5000 * 0.2 / 64 / 100]
- [21 * 5000 * 0.2 / 64 / 100] = 3点生命值 吸取
另一个例子, 9%生命吸取属性，圣骑士使用3K面板的热诚技能打地狱难度死亡甲壳虫:
- [[[9 * 1/2] * 64 * 1/3] * 3000 * 0.5 / 64 / 100]
- [[4 * 64 * 1/3] * 3000 * 0.5 / 64 / 100]
- [85 * 3000 * 0.5 / 64 / 100] = 19点生命值 吸取
粉碎性打击
Crushing Blow reduces the target's life by a fraction of their current life, so it's more effective against targets with lots of life and becomes less effective as they lose life. Attacks can have up to 100% chance to cause a Crushing Blow - any extra will have no effect.
- Crushing Blow now has greater diminishing returns against bosses (act bosses, map bosses, ubers)
- The melee life reduction is now the same as the ranged reduction
| Target | 近战 (PD2) |
远程 (PD2) |
近战 (LoD) |
远程 (LoD) |
|---|---|---|---|---|
| Most Targets | 1/8 | 1/8 | 1/4 | 1/8 |
| Super Uniques | 1/8 | 1/8 | 1/8 | 1/16 |
| Bosses | 1/80** | 1/80** | 1/8 | 1/16 |
| Players and Mercenaries | 1/10 | 1/10 | 1/10 | 1/20 |
* "Most Targets" refers to pets as well as normal, minion, Champion, and Unique monsters
** Affected by diminishing returns: 80 + pow(missing hp%, 2)

Open Wounds
- Open Wounds deals physical damage over time
- The damage depends on the level of the character who applies it (shown below for all levels)
- The damage is now affected by "+X Open Wounds Damage per Second" which is a new attribute that often accompanies "X% Chance of Open Wounds"
- The damage is now affected by Physical Damage Reduction (e.g. Battle Cry, Amplify Damage, Defiance, etc)
- The damage is not affected by other damage modifiers
- Open Wounds is now also applied by "Attacker Takes Damage of X" as well as attacks
- Open Wounds now lasts 5 seconds (was 8 seconds) and now stacks up to 3 times per target
- Open Wounds now has a ¼ penalty against mercenaries and pets
- Open Wounds no longer has a ½ penalty against stronger enemies (champions, uniques, super uniques, bosses, prime evils)

减少敌人抗性手段
Resistances are now reduced at 1/2 effectiveness (was 1/5 effectiveness) when those resistances are above 99% (immunes) or below 0%.
This effectiveness penalty only applies to effects caused by players and pets. Negative resistances caused by monsters (e.g. Conviction, Amplify Damage) are always applied at full effectiveness.
破免
These effects "reduce" or "lower" enemy resistances and will break immunities. They all apply an effect to the enemy which persists and reduces their resistance while it is active, which allows all players to benefit:
- 战嗥 (物理)
- 极地风暴 (冰冷)
- 猛毒花藤 (毒素)
- 伤害加深 (物理)
- 衰老 (物理)
- 降低抵抗 (火焰/冰冷/闪电/毒素)
- 审判光环 (火焰/冰冷/闪电)
- 庇护所光环 (魔法)
- 地狱之火 (火焰)
- 静电立场 (闪电)
These effects "penetrate" or "pierce" enemy resistances and will not break immunities. They only benefit the character who uses them:
- -% to enemy resistance from items or skills (e.g. Kira's Guardian, Rainbow Facet, Cold Mastery, Fire Mastery, Poison Strike, Berserk)
Effectiveness vs Immunes
All effects which "reduce" resistances (those that can break immunities) are applied simultaneously against immune enemies, rather than sequentially. This means that even if multiple immunity-breaking skills are used and one of them would be powerful enough to break an immunity alone, they all still apply at 1/2 effectiveness.
- As an example let's take an enemy with 110% fire resistance, and apply both Lower Resist and Conviction each at levels where they have "Enemy Resistances -30%":
- -30 / 2 = -15 [降低抵抗1/2属性生效]
- -30 / 2 = -15 [审判光环1/2属性生效]
- 110 - 15 - 15 = 80 [最终敌人受到的减抗后的数值]
Effects which "penetrate" resistances rather than "reduce" them (e.g. Rainbow Facet, Cold Mastery) will be applied afterward and will work at full effectiveness against enemies that have had their immunities broken.
Effectiveness vs Negative Resistance
When taking an enemy below 0% resistance, the effectiveness penalty only applies to whatever portion becomes negative. Everything applies at full effectiveness and then afterward, if the enemy's resistance is negative, it gets halved.
- As an example let's take an enemy with 25% cold resistance, and apply Lower Resist and Conviction from before as well as an extra "-12% to Enemy Cold Resistance":
- 25 - 30 = -5 [降低抵抗]
- -5 - 30 = -35 [审判光环]
- -35 - 12 = -47 [-敌人冰抗]
- -47 / 2 = -23 [最终敌人冰冻抗性]
抗性最大可减少-100%
物品掉落机制
物品掉落基础
让我们来看一个高级别的例子，了解下掉落程序是如何工作的。
墨菲斯托被击杀了! 游戏怎么决定你的奖励？
- 计算掉落物品数量（最大 6个）
- 选择物品类型（决定物品1.种类比如掉落帽子还是武器，2.品级比如是普通还是扩展亦或精锐）
- 选择物品染色（此步MF参与计算，物品是白，蓝，黄，绿还是暗金）
- 选择物品为暗金或套装内的哪一件（比如暗金戒指是乔丹还是乌鸦，套装项链是天使还是塔拉夏）
- 选择物品属性（如乌鸦dex/ar变量）
玩家数量只影响项目 # 1，潜在掉落的数量。它对掉落物品染色没有影响(这是MF发挥作用的地方)。现在的问题是，玩家的数量如何影响掉落的物品数量？
任何时候你做一些掉落物品的时间（如开箱子，杀死怪物等等），游戏会从一个宝藏级别（TC）的列表中选择，这将决定什么样的物品将掉落。每个TC都有一个可以掉落的物品列表，以及给该物品掉落的概率. 每个 TC 还有一些“picks”，它们决定了可能掉落的物品数量.拼图的最后一块是“ NoDrop”，这是一个选择不会掉落任何物品的概率。NoDrop 是玩家数量影响的唯一参数.
当更多玩家加入游戏时，新的 NoDrop 值是如何计算的，这里有很多问题，但简单来说就是: 玩家数量越多，NoDrop 的几率就越低(如果有足够多的玩家，NoDrop 的几率可能达到0)
有一些 TCs NoDrop就是0。这些不受玩家数量的影响，因为0是最低可能值.
What's different in PD2?
PD2 单人基础掉率大致与原版p5/5相当, 当一个游戏有8个玩家时，每个玩家的掉略都会提高，比原版8/8还要略高一些.这意味着所有 TC 的总体 NoDrop 要低得多，而且用更少的玩家更容易达到0的 NoDrop.
跟原版一样在多人游戏里你可以获得更多的掉落数，但是单一玩家和一个8人小组之间的差别总体上要小得多.
符文TCs跟原版一致, rune drop rates are the same. 微小的差异可能存在于某些情况下，由于新的有价值的物品的加入，如拉苏克谜盒的掉落
如何比较 PD2 与 LoD?
很难直接比较两者，因为有数百个 TC，而 PD2甚至比 LoD 还要多(主要是因为地图) ，但是我们可以比较来自 LoD 的 TC 和来自 PD2的 TC，看看 NoDrop 几率是如何变化的。
让我们看看名为Swarm 2 (H)的 TC。在这个例子中，第一个数字是游戏中的玩家数量，第二个数字是团队中的玩家数量。所以 p3/2意味着在游戏中有3个玩家，但在你的队伍中只有2个。如果在单人游戏中使用 /players 8 命令，那么等效于 p8/1。
Chance for NoDrop to be selected by the "pick" (i.e. the chance that no item drops):
LoD
- p1/1, p2/1 = 83.33%
- p2/2, p3/1, p3/2, p4/1 = 69.14%
- p3/3, p4/2, p4/3, p5/1, p5/2, p6/1 = 57.63%
- p4/4, p5/3, p5/4, p6/2, p6/3, p7/1, p7/2, p8/1 = 47.92%
- p5/5, p6/4, p6/5, p7/3, p7/4, p8/2, p8/3 = 39.02%
- p6/6, p7/5, p7/6, p8/4, p8/5 = 32.43%
- p7/7, p8/6, p8/7 = 26.47%
- p8/8 = 21.88%
PD2
- p1/1, p2/1 = 40.85%
- p2/2, p3/1, p3/2, p4/1 = 16.64%
- p3/3, p4/2, p4/3, p5/1, p5/2, p6/1 = 6.68%
- p4/4, p5/3, p5/4, p6/2, p6/3, p7/1, p7/2, p8/1 = 2.75%
- p5/5, p6/4, p6/5, p7/3, p7/4, p8/2, p8/3 = 0.99%
- p6/6, p7/5, p7/6, p8/4, p8/5 = 0.33%
- p7/7, p8/6, p8/7 = 0.17%
- p8/8 = 0%
钥匙掉率
这是一个很常见的问题，它可能是有意义的，只是显示下掉率是什么
P1和 p2-p8之间的区别很小，所以组队打钥匙没有必要了。
