Create a sticky for attribute formulas, hit cap, and such

[Lopherus]

I"m finding it hard to find precise information on how ratings such as AP were calculated in vanilla. The "vanilla wow wiki" is clearly none; it discusses hit rating, dks, later expansions, and such, and presents the appropriate formulas as they were (or are) at a later time. As an example, I know that the basic cat AP formula is *roughly*

Strength*2 + Agility + 20,

but I think, more precisely, it is

Strength*(Level factor +2) + Agility +20.

In the case of my lvl 24 druid, it appears level factor is a flat 4; but when trying to reconcile my bear AP, it would have to be a different number. So what is "level factor," and how does it vary by class (or within a class, cat vs bear, say)?

From looking at how AP translates to DPS, and going over a couple of cases, I also get varying results - 13.9 to about 14.1 (it's probably 14 AP = 1 dps).

(1) Is there a link to an organized and trustworthy collection of such calculations?

(2) If not, could we create a sticky here where people who theory-crafted in retail vanilla can add what they remember? (I've been around since early beta, but didn't care about such calculations for much of vanilla). Topics I think that should be covered could include:

AP
Crit (melee and magic)
Hit
Being critted (working towards being uncrittable)
Being uncrushable
(add what you think is important)

Edit: I added some based on my understanding; pls do add what you know, and correct if anything I added is not quite right.

Spell Hit (base chance to miss):
- Same level: 4%
- minus 1 level: 5%
- minus 2 levels: 6%
- minus 3 levels: 17% PVE, 13% PVP

For even greater level differences, chance to miss increases rapidly.

------------------------------------

Melee Chance to Miss (D: defense skill, WS: weapon skill):

(A) (D - WS) <= 10
5% + (D-WS)*0.1% if not dual-wielded
24% + (D-WS)*0.1% dual-wield

(B) (D-WS) > 10
7% + (D-WS-10)*0.4% if not dual-wielded
26% + (D-WS-10)*0.4% dual-wield

------------------------------------

Spell Crit % at lvl 60:

(Intellect/60) + Class Constant

It seems the class constant is such that for most classes ~60 int equal +1% crit; except for pallies where it might be as low as 54 int. Note also that the same int amount provides more crit at lower levels.

Glancing Blow:

Chance for a Glancing Blow:

10% + (D-WS)*2%

Increased WS from talents, etc., disregarded.

Damage reduction from a Glancing Blow:

(D-WS)*2%

Increased WS taken into account.

Example white damage calculations for a melee class:

Lvl 60 with maxed WS vs raid boss (lvl 63):

Chance for a Glancing Blow: 40% (= 10% + (315 - 300)*2%)
Damage reduction on Glancing Blow: 30% (= (315 - 300)*2%)
Effective white damage: 88% of stated (=60% + 40%*70%)

Level 60 with +5 WS vs raid boss:

Chance for a Glancing Blow: 40% (= 10% + (315 - 300)*2%)
Damage reduction on Glancing Blow: 20% (= (315 - 305)*2%)
Effective white damage: 92% of stated (=60% + 40%*80%)

Impact of Agility on Melee Crit Chance:

added Crit Chance = Agility/Class Agility Crit Factor (CACF)

CACF is about as follows:
- 29 for rogues
- 53 for hunters
- 20 for all other classes

Example + crit%:
Warrior with 100 agility: +5% (=(100/20)%)
Rogue with 200 agility: +6.9% (=(200/29)%)

--------------------------------------------

Player Dodge%:

Dodge Class Base Chance (DCBC) + Agility/Class Agility Dodge Factor (CADF) + (D - WS)*0.04

Note that the level of the attacked mob influences dodge chance (by the last term).

DCBC seems to range between 0 and 3% for the different classes.

CADF is about as follows:
- 14.5 for rogues
- 26.5 for hunters
- 20 for all other classes

This means that, as a rule of thumb, +20 agility give you +1% dodge; for rogues you get about 1/3 more, and for hunters about 1/3 less.

Example - lvl 60 warrior with 150 agility attacking a raid boss (lvl 63):

Assume a DCBC of 1%. Then:
Dodge Chance = 1% + 150/20 + (300 - 315)*0.04 = 6.9%

 

[Lopherus]

Mob chance to Dodge/Parry/Block a player attack:

5% + (D-WS)*0.04

Note:
- this means that a lvl 60 melee attack on a raid boss from the front allows the raid boss a 5.6% chance to either dodge, parry, or block the attack (=5% + (315-300)*0.04))
- when attacking from behind, parry and block chances are removed from the hit table

This, but a sticky thread by the devs (if they find time) would be nice, also to include things like base crit, etc., to have 100% confirmed information how it works on THIS server.
