Game Mechanics

Melee Splash

Melee splash is an instant AoE, with no Next Hit Delay, that damages all enemies 360° around the target. The main target does not take splash damage.

These are included in the splash:

• Skill damage
• Converted damage (Concentrate)
• Normal attack damage (the values you see when you select the regular attack as your skill)
• Elemental and physical damage charms and gear
• Critical Strike and Deadly Strike (still only applies to the physical damage)
• Life and Mana leech (at 1/2)

These are not included in the splash:

• Missile damage (such as the Nova portion of Power Strike)
• Stun
• Knockback
• Crushing Blow
• Open Wounds
• Any other on-hit effects

Melee Splash Examples

Let's take a look at a couple of examples. First, let's take an Amazon:

• Lightning Strike for 1-10000 lightning damage and 1-10000 chain lightning damage
• Normal attack damage of 1000-5000 (900-4900 of that is physical)

The total splash damage would be 1001-15000 damage.

And if they crit then the splash damage would be 1451-17450.

The 1-10000 damage from the Chain Lightning is not applied.

What about a Barbarian:

• Concentrate (300% ED, 50% conversion)
• Normal attack damage of 1000-5000 (900-4900 of that is physical)

First the physical portion of the normal attack damage is boosted by Concentrate's ED% bonus: 900-4900 becomes ~1800-9800

Then 50% of the physical damage is converted to magic

The total splash damage would be 1900-9900 [100-100 elemental damage + 900-4900 physical + 900-4900 magic]

And if they crit then the splash damage would be 2800-14800

Splash Radius

The base player melee splash radius is 3.33 yards but this can be extended by certain skills and items. The splash radius will increase every 20%, so there are breakpoints at 20%, 40%, etc.

Increased Splash Radius	0	20	40	60
Tiles	5	6	7	8
Radius (yards)	3.33	4	4.66	5.33

There are also a handful of other things that have melee splash. These are all static and cannot be increased.

• "Splashing" map modifier: melee splash radius is 3.33 yards
• Golems: melee splash radius is 2.66 yards
• Skeletons: melee splash radius is 2 yards
• Wolves: melee splash radius is 1.33 yards

Melee splash and ranged weapons

There are a few gloves (The Hand of Broc, Bloodfist, and Steelrend) that have melee splash on them and they can be used to give ranged weapons, like bows and crossbows, melee splash.

This allows shapeshifters to use a ranged weapon in place of a melee weapon, while still gaining the benefits of melee splash.

This does not mean that ranged attacks (i.e. shooting with a bow) will have splash damage. Melee splash is always limited to melee attacks.

Critical damage

Critical Strike and Deadly Strike have been rebalanced to improve itemization - they now each cap at 75% instead of 100% and multiply damage by 1.5 instead of 2.

There are 4 different types of 1.5x damage stats:

• Deadly strike: found exclusively on items.
• Critical Strike: used in the following skills - Critical Strike, Hunger
• Crit Mastery (melee): used in the following skills - Javelin and Spear Mastery, Claw Mastery, General Mastery, Polearm and Spear Mastery
• Crit Mastery (throw): used in the following skills - Javelin and Spear Mastery, Throwing Mastery

(An attack is only able to be melee or thrown, therefore only one Crit Mastery type will be taken into account.)

To calculate the chance that one of these stats rolls a crit:

1 - ((1 - MasteryCrit) * (1 - CS) * (1 - DS))

As an example lets take an Amazon with:

• 30% Crit Mastery from Javelin and Spear Mastery
• 52% CS from Critical Strike
• 25% DS from gear

1 - ((1 - .30) * (1 - .52) * (1 - .25)) = ~75% chance to crit

The theoretical maximum combined crit chance is ~96%

Crushing Blow

Crushing Blow is a percentage chance to reduce the target's current life by a fraction. The fraction applied depends on the target and the type of attack. Crushing Blow also caps at 100% chance -- any extra will have no effect. This is all unchanged from vanilla, however there are a few things that have changed.

The melee life reduction is now the same as the ranged reduction:

Attack Type	Melee (PD2)	Ranged (PD2)	Melee (LoD)	Ranged (LoD)
Default	1/8	1/8	1/4	1/8
Super Uniques and Bosses	1/16	1/16	1/8	1/16
Players and Mercenaries	1/20	1/20	1/10	1/20

There is also now a cap of 65% when fighting against Champions, Uniques, Super Uniques, and Bosses. So as soon as these monsters are at 65% life, then Crushing Blow will no longer do any damage.

Behavior of -enemy resists

Breaking immunities

What will break immunities:

• Battle Cry (Physical)
• Poison Creeper (Poison)
• Amplify Damage (Physical)
• Decrepify (Physical)
• Lower Resist (Fire/Cold/Lightning/Poison)
• Conviction (Fire/Cold/Lightning)
• Static Field (Lightning)

What will not break immunities:

• -enemy resistance on gear
• Cold Mastery
• Fire Mastery

敌人抗性高于 99% (免疫)

就像原版一样, 当减少敌人抗性施加到免疫敌人身上时，它的效果就会降低. 原版减少 1/5，但在PD2中减少1/2.即使是打破了免疫，破免技能的属性也只有1/2效果.

举个例子，对一个110火抗的敌人释放20级降低抵抗（-30%）和10级审判光环（-30%）

正确计算如下:

• -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]

“不”是这样的:

• -30 / 2 = -15  [降低抵抗1/2属性生效]
• 110 - 15 = 95  [降低抵抗后敌人破免]
• 95 - 30 = 65  [审判光环不打折减少敌人剩余抗性]

值得再次强调的是，即使破免了，破免技能“仍然”也只有1/2的效果.然而，装备上的减抗属性、支配冰冷和支配火焰的减抗却并非如此.虽然这些减抗属性不能造成敌人破免，但在破免后，这些属性100% 生效不打折.

敌人抗性在 0% 到 99%之间

和原版效果一致.

所有降抗手段100%生效.

Enemy resists below 0%

When taking the enemy below 0% resistance you also have to apply the 1/2 penalty. This also applies to gear and items with -enemy resistance.

As an example lets take an enemy with 25 cold resistance, and lets apply a level 20 Lower Resist (-30%) and a level 10 Conviction (-30%):

• 25 - 25 = 0  [the first -25% from Conviction is reduced at 100% effectiveness]
• -5 / 2 = -2  [apply the 1/2 penalty to the remaining -5% from Conviction]
• -30 / 2 = -15  [apply the 1/2 penalty to Lower Resist]
• 0 - 2 - 15 = -17  [final enemy cold resist]

Resists can be reduced to a maximum of -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？

1. 计算掉落物品数量（最大 6个）
2. 选择物品类型
3. 选择物品染色
4. 选择物品是暗金还是套装（当可适用时）
5. 选择物品属性（当可适用时）

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？

Any time you do something that drops loot (opening a chest, killing a monster, etc.) the game selects from a list of treasure classes (TC) that will decide what kind of items will drop. Each TC has a list of items (or other TCs) that can drop, as well as a probability that that given item will drop. There is also a number of "picks" for each TC that decides how many potential items can drop. The last piece of the puzzle is "NoDrop", which is a probability that a pick will drop no items. NoDrop is the only parameter that player count affects.

There's a lot that goes into how the new NoDrop value is calculated when more players join the game, but the short version is: the higher the player count, the lower the NoDrop chance (potentially reaching 0 with enough players).

There are some TCs that start with NoDrop at 0. These are not affected by player count, since 0 is the lowest possible value.

What's different in PD2?

The baseline drop rate in PD2 is roughly equivalent to vanilla's p5/5 (5 partied players in a game) for solo play, and scales up per player until it's slightly above the equivalent of vanilla's p8/8 when there is a full game of 8 players. This means that overall NoDrop for all TCs is significantly lower, and it becomes easier to reach a NoDrop of 0 with fewer players.

You still get loot increases from more players like vanilla, but the difference between a solo player and a group of 8 is overall much smaller.

Rune TCs are also the same as in vanilla, so rune drop rates are the same. Miniscule differences may exist in some cases due to new valuable items such as Larzuk's Puzzlebox being able to drop.

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):

• 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%

• 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。
