攻击投掷

平均攻击投掷为

2 * 主要攻击属性 + 1 * 次要攻击属性 + 2 * 技能等级

以魔法飞弹作为例子说明

魔法飞弹以感知作为主要攻击属性，智力为次要攻击属性。

一个拥有4感知与3智力的角色如果将他的魔法飞弹等级至6，那么他施展魔法飞弹时的平均攻击投掷便是:

2*感知 + 1*智力 + 2*魔法飞弹
=2*4 + 1*3 + 2*6
=23

(注意：一些物品给予投掷上的奖励与惩罚，种族特色亦会影响这个值；平均投掷只反映期望，每次的投掷结果高低不定)

对手的防御投掷也使用相同的计算方式，此处若以 抗魔 抵抗飞弹，平均防御投掷为：

(假设对手属性为5意志4智力并拥有等级7的抗魔)

(2*意志 + 1*智力 + 2*抗魔)*1.2
=(2*5 + 1*4 + 2*7)*1.2
=33[33.6] (地下城世界的所有投掷都使用去尾处理，小数部分忽略)

(注意：一些物品给予投掷上的奖励与惩罚，种族特色亦会影响这个值；平均投掷只反映期望，每次的投掷结果高低不定)

当攻击投掷(实际投掷结果，并非平均投掷)高于防御投掷时攻击有效。

Damage Roll

The basic damage roll is:

primary damage attribute / 2 + secondary damage attribute / 3 + skill level / 2

Example: Brawling

Brawling has strength as its primary damage attribute, and constitution as its secondary damage attribute.

If your hero has 4 strength, 6 constitution and level 8 brawling, the average damage roll is:

strength/2 + constitution/3 + brawling/2
=4/2 + 6/3 + 8/2 
= 2 + 2 + 4 
= 8

(note: some items lend an additional bonus or malus to this value)

Effects of spells and skills are calculated in a similar manner.

Test Rolls

After the average value has been determined, there will be a simulated dice roll. Different dice with values from 0 up to a maximum value will be rolled. Fractions are rounded down.

Example:

die	average	value
D3	1	0, 1, 2
D5	2	0 - 4
D7	3	0 - 6
D9	4	0 - 8
D11	5	0 - 10
D13	6	0 - 12
D15	7	0 - 14
...	...	...
D (2 X +1)	X	0 - 2 X

Depending on the average value of the test roll more than one die will be used. A D15 is usually the maximum dice value (dice value from 0 to 14) There will never be more than 6 similar dice at any given time. To make sure that the average roll equals the average value, an additional smaller die will be used in the calculation.

Example:

average	die
1	D3
2	D5
...	...
7	D15
8	D15 + D3
9	D15 + D5
10	D15 + D7
...	...
14	2 D15
15	2 D15 + D3
16	2 D16 + D3
...	...
42	6 D15
43	6 D15 + D3
44	6 D15 + D5
46	6 D15 + D7
47	6 D15 + D9
48	6 D17
49	6 D17 + D3
50	6 D17 + D5
...	...
53	6 D17 + D11
54	6 D19
55	6 D19 + D3
...	...
