Note that the numbers in this sheet are 'reverse engineered', so I wrote down large amounts of damages, speeds etc., and extracted the values in this sheet from those. So there is no guarantee that they are correct, but they did seem to fit, apart from a few minor deviatations.

- Weapon damage is multiplied by the number in the second column, so if your melee is at B, your weapons will do twice their listed damage. And if it's D- (multiplier 1.2), and you wield a 30-50 damage weapon, you will effectively do 36-60. (Apart from contributing attunements.)
- Block chance is listed in the third column. If you use a shield with a fast or normal weapon or focus, multiply this value with the shield multiplier. So if your melee is D+, you will block 16% of all attacks (melee, ranged or magic), and with a medium shield (x1.5), that will become 24%.

Block chance is dependent on difficulty; numbers given are for 'normal'. On easy the numbers are the same, on hard they're 3/4, on expert 1/2 and on nightmare 1/4 of normal (rounded down). So on hard, with melee B-, block chance is 3/4 * 24% = 18%. And on nightmare, even with melee at S, you only have 11% block chance.

Block chance is the same against any type of attack; even spells.

- Dodge chance is listed in the third column. Some attunements multiply this value.

Dodge chance is the same against any type of attack; even spells.

Dodge chance is dependent on difficulty; numbers given are for 'normal'.

On easy the numbers are the same, on hard they're 3/4, on expert 1/2 and on nightmare 1/4 of normal (rounded down).

So on hard, with speed D+, dodge chance is 3/4 * 16% = 12%. - Base attack speed is listed in the last two columns. It's workings are further explained after the table.

ability value | damage multiplier | block / dodge | base speed | base delay |

F | 1 | 5 | 133% | 3 |

E- | 1.05 | 9 | 139% | 2.875 |

E | 1.1 | 10 | 145% | 2.75 |

E+ | 1.15 | 11 | 152% | 2.625 |

D- | 1.2 | 14 | 160% | 2.5 |

D | 1.25 | 15 | 168% | 2.375 |

D+ | 1.3 | 16 | 178% | 2.25 |

C- | 1.4 | 19 | 188% | 2.125 |

C | 1.5 | 20 | 200% | 2 |

C+ | 1.6 | 21 | 213% | 1.875 |

B- | 1.9 | 24 | 229% | 1.75 |

B | 2 | 25 | 246% | 1.625 |

B+ | 2.1 | 26 | 267% | 1.5 |

A- | 2.3 | 32 | 291% | 1.375 |

A- | 2.5 | 33 | 320% | 1.25 |

A+ | 2.7 | 34 | 356% | 1.125 |

S | 3 | 45 | 400% | 1 |

Examples: if your speed is S, you have 400% / 1 = 400% speed, and if it's F you have 400% / 3 = 133% speed (without equipment; see below).

Base attack speed, as you find in the table above, is modified by your equipment: wielding heavier / bigger items means your delay increases. The table below lists the specific multipliers, and for convenience also the change to speed as a percentage: speed (%) multiplier = 1 / delay multiplier. (The speed % multiplier is rounded to 2 digits, which can give slight rounding differences.)

Note that the armour type (light/heavy) doesn't influence speed, only its weight.

equipped item | speed (%) multiplier | delay multiplier |

fast weapon / focus | 1.0 | 1.0 |

normal weapon / bow | 0.67 | 1.5 |

heavy weapon / focus | 0.5 | 2.0 |

small shield | 0.91 | 1.1 |

medium shield | 0.8 | 1.25 |

large shield | 0.67 | 1.5 |

armour | 1000 / (1000 + total weight) | 1 + (total weight / 1000) |

deadeye | 0.77 | 1.3 |

Example 1: your speed is C (base 200%), you use a normal weapon, medium shield, no armour:

your attack speed will be: 200% * 0.67 * 0.8 = 107%

calculated with delay factor: 2 * 1.5 * 1.25 = 3.75 (check 400% / 3.75 = 107%)

Example2: your speed is C (base 200%), you use a fast weapon, no shield and have armour weighing 400:

your attack speed will be: 200% * 1.0 * (1000 / 1000 + 400) = 200% * 0.71 = 143%

calculated with delay factor: 2 * 1.0 * (1 + 400/1000) = 2 * 1.0 * 1.4 = 2.8 (check 400% / 2.8 = 143%)

Example 3: your speed is S (base 400%), you use a bow (normal speed), no shield, no armour, and have deadeye - III active:

your speed is 400% * 0.67 * 0.77 = 206%

and the delay: 1 * 1.5 * 1.3 = 1.95 (check: 400% / 1.95 = 205%)

now, if you forget to unequip an (ineffective) medium shield:

your speed will even be 206% * 0.8 = 164% (or 1.25 * 1.95 = 2.44)

So you can see that you get twice as many attacks in with a fast weapon as with a heavy weapon. And coincidentally, comparable heavy weapons will do about twice as much damage. That is, not counting armour: if the first 10 points of damage are absorbed, I prefer once 24 - 10 = 14 damage to twice 12 - 10 = 2 damage! But then again, fast weapons have twice as many chances to score critical hits, and to trigger their active attunements. All in all, there is enough game balance here to pick your own favourite, or even carry weapons of different categories for different situations.
