Combat System - Hit And Damage Calculation

Attack Roll

The basic attack roll is:

2 * primary attack attribute + 1 * secondary attack attribute + 2 * skill level

Example: Brawling

Brawling has dexterity as its primary attack talent, and agility as its secondary attack attribute.

If your hero has 3 dexterity, 5 agility and rank 8 brawling, the average attack roll is:

2*dexterity + 1*agility + 2*brawling
=2*3 + 1*5 + 2*8 
=6 + 5 + 16 
=27

(note: some items lend an additional bonus or malus to this value) (note: each roll will deviate randomly up or down)

Your opponents defense defense roll is calculated in a similar manner.

Your opponent may use 2 skills for parrying your attack(Dodge blow, Use shield) or just natural defenses. See defense roll to find out which attributes are used.

If your opponent is using Dodge blow and has 4 dexterity, 6 agility and rank 6 dodge blow, the average defense roll is:

(2*dexterity + 1*agility + 2*dodge blow)*1.1
=(2*4 + 1*6 + 2*6)*1.1
=(8 + 6 + 12)*1.1
=26*1.1=28 (calculations in WoD are always rounded down)

(note: some items lend an additional bonus or malus to this value) (note: each roll will deviate randomly up or down)

If the attackers roll is higher than the defenders, the damage roll will be initiated.

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
...	...
