What is the formulas for probabalites to resist 25%, 50%, 75% and 100% of spel damage , based on spell level and resist ?

Not quite im looking for, since its

1) For level 50 spells
2) Give resistance probabality with increment of 50, while i want to find probabality for any value of resistance i might have.

It's 5x lvl, so for lvl 60 spells its 300.

Since 300 gives 75% resistance, I'd assume that its resistance / 400.

Thus say 127 resistance would generate (127 / 400) * 100 = 31.75% overall resistance.

This is essentially what I assumed in my original post. But it still doesn't asnwer the question of the exact breakdown of partial resistances.

Resistances only break down in 0/25/50/75/100, so its really impossible given the large luck factor to determine how exactly the resist table is applied.

Well, there's clearly some formula -- I can't imagine it'd be too hard to engineer. The average expected reduction will always be (resist/level)*15%, capped at 75%, but the question of "What % of the time will I get a 75% resist if I have 141 FR vs. a level 63 mob?" should be answerable. Not really important to answer, but answerable nevertheless.

Yeah, I just never really saw a reason to care.

Er, 3.25%, that is. Still, it's odd. The dependence on Agi and Skill seems pretty clearly worked out, but there's a constant term that seems to vary by class (and is 0 for classes where it actually counts). Probably just put there so that casters still have nonvanishing melee crit chances.

It looks like crit% is given by:

X + Agi/(Y*Lvl/60) + (Skill-TargetDefense)/25 , where X and Y depend on class.

Well, it seems to be 0.9% for Druids, which is at least significant. It's 0 for all other classes who actually care about melee crit (although I've forgotten to ask a Paladin or Shaman).

The big question still missing here is chance to hit (or miss). How is it affected by level and skill (and anything else)?

Also, do chance to miss, dodge, block, and parry all stack additively? Can any melee user with a combat log parser confirm this?

Well, first of all, miss is supposed to be purely player based, unlike dodge, whatever is being attacked is irrelevant. Basic attacks (one-handed and two-handed) versus an equal level monster is 5% chance to miss. This is increased to 24% when dual-wielding, but instant attacks (unsure about on-next-hit) retain the 5% miss rate.

For dodge/parry/block, each point in defence over your opponent's weapon skill adds a 0.04% modifier.

The way that I have seen crit/hit/miss shown (from player perspective) is that it exists within a bar,

---------------------------------------------------------------------
|             Hit            |  Crit   |
---------------------------------------------------------------------

It's like rolling a D20 in D&D; below a certain threshold you're missing (or if your DM is an ass, cutting off your own feet :angry: ), otherwise you hit normally, and if you're lucky, you crit.

Based on the above, and since Blizzard is unlikely to design two completely seperate combat calculation systems, I would assume it acts something like this:

---------------------------------------------------------------------
| Parry | Dodge | Block |         Get Hit          |
---------------------------------------------------------------------

Of course, Parry and Block are reliant on being able to, ie: having a shield and training in parry or getting it via talents.

One last thing to note is that all special effects; parry, block, dodge and crit are calculated as a portion of misses. Even if you missed the monster, you might still have rolled a critical. This just means that your critical strike missed. It sounds silly, but this is from the mouth of a CM.

XI- · 01/13/06, 6:07 PM

You're misunderstanding the CM.

Here's how WoW rolls. For example 30% crit 5% miss would be like this

1-30 crit
31-95 hit
95-100 miss

If we add 5% more crit it becomes

1-35 crit
36-95 hit
95-100 miss

You can never miss a crit. The interesting theory that no one's been able to test is what happens if your crit exceeds 100 - Miss %.

Should give you over 100% crit. Equip two weapons and go duel someone. Or stick with 1 weapon and keep your hit% gear on.

Zellyn · 01/13/06, 6:16 PM

What about abilities like Elemental Mastery and Cold Blood which are supposed to cause a 100% crit chance?

Edit: According to Thottbot, EM and CB have a seperate modifier function "Apply Flat Modifier", while Recklessness has "Mob Crit Percent", which is the same thing that +crit equipment have as a modifier. As such, I think that CB and EM may be calculated as criticals after they hit (if they hit).

hamlet_the_lesser · 01/13/06, 6:19 PM

hmm that is an interesting question. I am curious how you determined that a crit cannot miss. Did blizzard state it? Or are you going off the parseing of data. I really would like to know what happens at that point and wonder when blizzard will change it's mechanics.
