Warlock pet scaling

[Mephisto22]

Every single private server has to find their way around pet scaling. At first I thought that the goal of having them completely blizzlike may be impossible. But then I did deep research.

1. I have tested following rules which should apply to each pet:

   1 Stamina Point = 0.3 Stamina for Pet 
   
   1 Resistance Point = 0.4 Resist for Pet
   
   1 Armor Point = 0.35 Armor for Pet
   
   1 Spell Damage (of your highest spell dmg school) = 0.15 SP and 0.57 AP
   
   1 Intellect Point = 0.3 Int for Pet
   

So far all numbers were correct. However, the tricky part is that all the pets actually scale differently. They dont scale like players – 1 stamina equals 10 hp. They have different scaling factors, thats why voidwalker gets more hp from stamina, they are balanced around those factors which are, unfortunately, secret to us and most private servers usually just try to make up their own scaling factors and base statistics of the pets.

I focused on fellhunter which is the most important pet for PvP. In these videos you can see hp and mana of a fellhunter and also warlocks stamina and intellect.

https://www.youtube.com/watch?v=aDGtKZ-xRuo 0:27

https://www.youtube.com/watch?v=fmVkJTmKiFE 0:26

I compared those numbers to corecraft. I had the same spec, almost the same amount of stamina and intellect (+/- 1) and the numbers were different:
First example: My felhunter had 5845 hp instead of 6127 as shown in the first video.

I found out that corecraft uses these scaling factors: 9 HP per 1 point of stamina and 11 mana per 1 point of intellect for fellhunter. They are obviously wrong.

Following calculations are done with all talent modifiers:
Pet stamina with naked warlock = 353 and that is 3595 hp on corecraft
353 * 9 = 3177 hp from stamina. Therefore 3595 – 3177 = 418 (probably HP fellhunter has with 0 stamina ?? )
Naked lvl70 UD warlock 88 stamina – (88 *0,3) * 1,15 = 30,36 stamina for pet =´273,24 hp
Pet basic stamina = 322,64 = 2903,76 hp
2903,76 + 418 = 3321,76 HP which pet has on his own
Warlock with 813 stamina – pet gains 2250 HP from his gear on CC
3321,76 + 2250 + 273,24 = 5845 total HP

So now I have to find basic HP of fellhunter which he theoretically has without warlock and correct scaling factor of his stamina so that it would match data from both retail server videos. According to the first video he should have 6127 HP with warlocks 813 stamina. And from second video he should have 4702 HP while warlock has just 377 stamina.

Simple linear equations:
[(813 * 0,3) * 1,15] x = 6127 – y
[(377 * 0,3) * 1,15] x = 4702 – y
To make it shorter, X = 9,4734742721 – this is the stamina factor scaling
Y = 3469,8325688 this is HP without warlock – so it is more than on corecraft
Pet gains a little bit more HP from warlocks gear

Fellhunter would have on retail in S4 gear around 400 hp more than on CC...... So to sum up, completely Blizzlike Fellhunter HP scaling mechanic before warlock stamina and talents would be as follows:

BASIC STAMINA without any contribution of warlock stats (even naked warlock stats) should stay the same as it is so that this change doesnt mess up with Demonic Knowledge talent: 280,1261052606596 stamina
BASIC HEALTH of fellhunter with 0 stamina: 418
SCALING FACTOR OF STAMINA: 9,4734742721 HP per 1 point of stamina

I did exactly the same for Mana and the results are:
BASIC INTELLECT before warlock and talents: 131 intellect
BASIC MANA: 905
SCALING FACTOR OF INTELLECT: 11,506368028 mana per 1 intellect point

Now lets check it out with talent modifiers and compare it with video:

For HP: 418 + [(280,1261052606596 * 1,15) * 9,4734742721] + [(813 * 0,3 * 1,15) * 9,4734742721] = 6127,000000009969

418 + [(280,1261052606596 * 1,15) * 9,4734742721] + [(377 * 0,3 * 1,15) * 9,4734742721] = 4702,000000000687

For Mana: 905 + [(131 * 1,15) * 11,506368028] + [(375 * 0,3 * 1,15) * 11,506368028] = 4127,0707070407 as it can be seen in the first video

I could do the same thing for other pets but I need videos with alike information and that would be much harder to find. Also Felguard is horribly bugged, his dmg is way too low, I will have a look at him and post into this topic asap.

[Mephisto22]

Felguard is doing almost the same dmg as other pets, he should be doing much more, it was reported that in T5 instances he is capable of 300-400 DPS.

In this link you can see people stating what dmg felguard does with certain amounts of spell dmg.

Link : http://www.wowhead.com/spell=30146/summon-felguard#comments:0

„With 700SP – 250-350 melee swings on cloth target“
On Corecraft my felguard does cca 170-220 melee swing on cloth targets with 800 Spell power.

Attack power that your pets get from your spell power is correct, which is 57%. The problem has to be in AP to DPS ratio or in felguards base weapon DPS. Lets find out – last post on this page:

http://wowmb.net/forums/f9/13262-felguard_how_use_what_wear/p5/

Thank god for this picture, we can gather some crucial data:

http://s23.photobucket.com/user/apep_wow/media/FG_3K_AP_052307.jpg.html

AP: 3146, as we can see it gives 224,7 DPS
I did the math and on CC it would be the same number, the AP / DPS ratio is correct. This leaves us with basic weapon DPS that felguard does with 0 AP. It is too low.

From the Picture we can get the overall DPS very easily: Melee dmg is 763-819 and that is |[(819-763) / 2] + 763| /2 = 395,5 DPS (with + 20% +5% +5% modifiers from talent, soul link and MD -multiplicative stacking)

X + 0,2X = 395,5 ................ X = 329,58333333
X + 0,05X = 329,58333333 ............... X = 313,88888889
X + 0,05X = 313,88888889 .............. X = 298,94179894 (this is the DPS before talent modifiers)

This is felguard blizzlike pure weapon DPS before talents and AP contribution:
298,94179894 – 224,7 = 74,24179894 DPS

This is at lvl 70, I do not know if his weapon DPS does change with lvl. The current pure weapon damage at level 70 has 35 DPS and that makes Felguard spec completely broken. According to one wowhead post he should do 200+ hits at lvl 60 therefore I suposse that his weapon DPS does not really change with level:

on 2006/12/29 (Patch 2.0.1)
"my fel guard hits for 200+ dmg per swing at lvl 60 not including any spells"

74,24179894 DPS + 224,7 DPS = 298,94179894 + 20% + 5 % + 5% = 395,5 DPS as shown in the picture. After this fix the damage should be just as described in wowhead posts.

[Mephisto22]

Another tiny bug that I found: talent Unholy power that increases pet damage by +20% stacks with Soul Link (+5%) additively and not multiplicatively.

Additive stacking : X * ( 1 + 0,2 + 0,05)
Multiplicative stacking : X * 1,2 * 1,05

Unholy power is a damage increase through talent and Soul Link is a damage increase through castable buff, they should not have additive stacking. This results in 2-10 damage loss per swing depending on your gear and buffs.

[ccshiro]

We've previously done all the calculations for scaling of hp, armor and mana. The reason they're not correct on the server seems to be a rounding error in the scaling code. I've double checked my calculations and the following is all correct (given that the rounding error gets fixed):

• base hp and scaling of all pets
• base mana and scaling of all pets
• base armor and scaling of all pets
• base mp5 of all pets (not scaling)
• other base stats of all pets (str, spi, agi)

What isn't done:

• scaling of resistance
• scaling of mp5
• The way dps is calculated

Any input on the last three points would be nice. I wouldn't spend time running the calculations on the things that are already completed, just verify that they work next test after the rounding error has been fixed.

[ccshiro]

I've fixed the rounding error. The three aforementioned points still need looking at (resistance, mp5, damage).

[Aasamath]

I came accross this thread http://www.arenajunkies.com/topic/26518-tom-chilton-pets-are-just-fine/page__st__140
It was made during 2.4.2 some guys says he has 109 spell pen, leaving a demono's spec fellhunter with 101 resist unbuff.
That means 210 resist, so 140 base + 70 with "master demonologitst"
On the server i have 238 resist/ 242 shadow (undead)

Next post talks about 350 resist with the warlock trinket 210+130=340 (missing 10poitnt somewhere)

An other post from same link but on page 7
"a void star talisman - this trinket increases all pet resistances by 130, with 5/5 master demonologist my felhunter has 368 all resistances unbuffed)"
With the current formula on the server my pet has 368 resist/ 372 shadow with the trinket.

The last post i quoted seems to be the one that was made with the more "care" so i'd say it's more accurate on the resist value than the others.
Current formula would be okay about resists then.
Very little detail though, all of them talk about having same resists to all school, whatever the race. So maybe the 10 points from racial shoudln't be transfered, or maybe they don't mention it because it's just 4 points more.

[Aasamath]

About damage there is an incomplete list of succubus stats per level (lvl 70 are there though) on this thread. If i'm not mistaken, by looking at the "edit history" this was written in march 2008
http://wowwiki.wikia.com/wiki/Succubus_(warlock_minion)?oldid=1565074

edit: from the screen you linked i compared resistance with the same buffs on corecraft

Here is a screen of my lock and pet buffed with improved drood mark and shadow resist just like on the retail screen.

the 4points of racial resits are transfered too btw, so i think we're good about resists

[Aasamath]

Found some stats of ap and dps scaling for pet at the bottom of this page.
They date of 3.3.3 though. I don't know if scaling was changed at wotlk (ratio ap/dps for felguard is the same as the tbc screenshot)
http://wowwiki.wikia.com/wiki/Spell_power_coefficient#toc

some additional info about pet attack power (stats are for lvl 60 during tbc prepatch):
"At the moment all of our pets receive the same percentage bonus, and they all have the same base melee attack power (238), except for the imp who has 112 base. The imp doesn't melee at all though so at the moment the imp basically doesn't scale."
http://wow-tng.org/showthread.php?2054-Felguard-Video-and-Warlock-Pet-Scaling

seems after 2.0.3 felguard nerf, he still had the same attack power, must be base dps that was nerfed, or ap/dps ratio
"My Felguard in 2.0.3 on live has 238 base power"
website is down so here's the google page where you can read that, it's the second link
https://www.google.fr/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=felguard+2.0.3

So if base ap was also the same for all pet at lvl 70 (except imp) and the succubus stats from my previous post are correct, then base ap would be 286.

[Aasamath]

Other lvl 60 stats at 2.0, problem is i don't know what stats and talents the warlock had
(soul link or not mostly and this was the pre 2.0 soulink: 3% damage boost) other issue is that pet scaling might have been different later on (tlk and pre-tbc patch linked above say different things)
Also felguard dps is wrong since this was before nerf

round 2:
vw vs owl; no pet skills; 41 demonology/no hunter talents; 4805vs/3611owl HP; 5360/4255 AF; 251/359 AP; owl 0%/vw 1400HP at end of fight
round 3:
succ vs owl; no owl skills; 41DM/no hunter talents; succ = 2402HP/2699AF/82.5DPS/251AP = succ beat owl with 128HP left
round 4:
felguard vs owl; no pet skills; 41DM/no hunter talents; FG = 3432HP/3357AF/90DPS/251AP = FG beat owl with 1100HP left

http://www.dual-boxing.com/threads/10062-Stats-for-level-70-felguard
This confirms lvl 60 pet (imp excluded) had same ap though the number is different than above posts, might be gear

[Aasamath]

THIS POST SEEMS TO BE INVALID DUE TO TLK CHANGES:

i so hope stats and scaling didn't change at 3.0.2 cause dat guy might save us
patch 3.0.2: Felguard: Health increased by 10%
should mean he only has more sp than before because of demonic knowleged
https://youtu.be/w6tZkIJqvE4?t=35
note that soul link damage boost was removed at that patch, demonic tactics should be unchanged (patchnote is 3.0.3), master demonologist and unholy power haven't changed. Demonic brutality was added but only increase frenzy % so he doesn't bother us here.

calculations from this video gave me those stats:

pet ap/14 = bonus dps
pet has 240 sp it's 15% of the 1603 shadow damage

pet dps if master demonologist talent is multiplicative
x+ 0.2x + 1.2x*0.05= 180.6
1.26x=180.6
x=143.3 dps untalented
143.3-83.4= 60 base dps 0 ap
143.3-62.9= 80.4 dps with 286 basic ap

pet dps if master demono is additive
or x+0.2x+0.05x = 180.6
1.25x= 180.6
x=144.48 untalented
144.48 -83.4= 61.08 base dps
144.48-62.94= 81.54 dps with basic ap

slight problem the ratio pet ap/ master spell power isn't 0.57
1603x0.57=913.71
(1603+1469)/2x0.57 =875.52 (average shadow and fire damage calculation)
on video pet has +881pa

Please verify my math, i used to fell asleep during class ^^

https://youtu.be/Zpx4liKIfJY?t=542
same guy but with voidwalker, calculation might prove more tricky though
patch 3.0.2: Voidwalker: Health increased by 20%, Damage increased by 16%. The amount of attack power the Voidwalker gains from its master's spell damage has been increased by 45%.

EDIT: after comparing stats from tbc and early tlk for the same pet, it seems many things have changed concerning pets. I tried using changelog info to obtain tbc numbers, but it's pulling different numbers than the tbc video from below.
I'll leave the post in case someone wants to make the math themselves

Only thing that is confirmed, is that base ap of lvl 70 pet is indeed 286 (tbc succubus from wiki link, felguard and voidwalker in tlk video)

[Aasamath]

about pet stamina and intel i found that post http://wowwiki.wikia.com/wiki/Demonic_Knowledge
edit was made in january 2008
i compared the spell power gained on corecraft. Assuming cc uses the pre-2.4 formula, i did my own calculation with a 15% bonus instead of 12.

succubus: 82 retail / 82 cc
fel guard: 82 retail / 82 cc
imp: 96 retail / 85 cc 101.5 with rank 6 blood pact
void: 71 retail / 88 cc
felhunter: 133 retail / 82 cc
tested with fel stamina and fel intel maxed
edit: i tried on undead, forgot races have different stats...

oh an btw PRE WOTLK VIDEO WOOT! of voildwalker... could have been better, but considering he is the one that got changed the most at tlk, it gives us a baseline.
https://youtu.be/hiODseoH2PM?t=28
he doesn't show pet damage and ap, but i could get one them in slowmotion.

Here are some info pulled from the tbc video, some are blank for now because i miss the data on the video (pet mana, warlock intel and stamina) im might be able to use @Mephisto22 's posts for that

Base stats of a 70 voidwalker
base str: 153
base agi: 109
base spirit :122 (undead at least)
base health: 869
base armor: 9070 (44.589% reduction ?) 9784 is 48.10% reduciton

scale ap: 57%master
scale armor: 35% master
scale stamina/hp: 13.58
scale intel/mana: 10.6
_base ap: 286 (20.4 dps)
_base dps: 14.3
_base dps +ap: 34.7
base mana: unknown
?scale intel:
?scale stamina:

I'm stuggling here, i can't find a talent build that would give me base pet stamina and intel able to do the calcutation from this page: http://wowwiki.wikia.com/wiki/Demonic_Knowledge
so either this page is wrong or i need to determine which race he was when he reported that.
?base intel:133 (talented?) 115 (if 3/3 fel intel)
?base stamina: 308 (talented?) 267.8 (if 3/3 fel stamina)

_ratio ap/dps assumed at 1/14 like felguard, viable on voidwalker 3.0.2 video
?those one can be caculated if i can find retail base hp,mana, intel, stam of 70 undead warlock (saw a report saying corecraft race statistic boost were wrong)

intel tootip (133 +113) gives 2625 mana 6.41% crit
spirit tooltip 122 spirit gives 22 heath /s 19 mp5 while not casting (might need a german to confirm the tooltip translation ^^)
stamina tooltip 308+302 gives 8287

[Mephisto22]

That info about Demonic Knowledge numbers from wowwiki is 100% pre-nerf. I dont remember the details but I realized that 2 months ago. As for Voidwalker / Felguard stamina to HP ratio you can test it empirically. Equip an UD lock on CC so that void has 610 stamina and check for his HP. Do the same with gnome and Felguard (u might need some buffs from other players). And Felhunter - if it works now according to my first post. Then post here the results so that we can see if there are still bugs with stats.

Mana regen:
last time I checked pets had like infinite mana regeneration while not casting, I guess they use masater's mp5 but I am not sure, I didnt have time for that

Damage:
Well, I did the math for Felguard and I believe I am right
As for Voidwalker, how did you get these base DPS numbers? I would need to see the DPS he gets from 870 AP. You can check this on CC too and see if it is correct or not.

Have fun, I deleted WoW and I am probably not going to participate in next test :)

[Aasamath]

Yeah, nice input. I'll go look at stats of classes an void tomorrow while server is still up. And i'll do the Demonic Knowledge calculations with other races too.
About the base dps i used the 1/14 pet dps/ pet ap ratio since your gnome screenshot seems to work with it.
So 870/14= 62.1 dps (i'll go verify on cc too)
total dps - ap dps = 76.4 - 62.1= 14.3 base dps
base pet ap is 286 giving 20.4 dps
"naked dps" = base dps + ap dps = 34.7

ps: warlock has only 15 points in demology, pet dps isn't boosted at all by talents, or buffs.

As for your felguard calcuation they are just missing two parameters.
First one is mutiplicative % of SL like you stated after, this seems legit.
Though i also wonder if master demonologist shouldn't also be mutliplicative, since it could be considered a buff.
Other problem is that pet is just coming back from melee, so he probably has stacks of Demonic Frenzy. We could assume 10, so 50% more ap considering the high base ap of the pet in comparison to the lock gear.
If we can integrate that last parameter we should be pretty close, since differences from sl and demonic knowledge being additive or mutiplicative are quite small.

[Mephisto22]

I would have thought that Voidwalker has different AP to DPS ratio from Felguard.

Demonic Frenzy buff doesnt really matter because it increases attack power and not total damage done, he has totem buffs, pala buffs etc. , the only thing that matters is his total AP and additional DPS it provides. I used multiplicative stacking for all % damage modifiers because I dont really see a reason there should be additive stacking. According to info from elitistjerks everything is multiplicative except for damage increase that comes directly through talents.

I checked Contagion, Shadow Mastery, Imp CoA and they have additive stacking with each other. I checked Emberstorm and Improved Immolate - additive stacking as it should. Then I checked Soul Link with Master Demonologist and they had multiplicative stacking as they should. but... something seemed to be wrong, numbers were a little bit different... then I thought that maybe MD behaves as damage increase directly through talent even though it is a buff, I tested both and found out. suprisingly, that SL stacks additively with Unholy Power. And I dont see any logic behind that. Castable buffs (and debuffs) should stack multiplicatively, addons and damage spreadsheets support that as well.

I included all decimal numbers, because any rounding would mess up with my calculations, but it should be very close to the real numbers. Well, it was hard for retail players to get the real numbers, I remember Blizz stating that they compared some numbers from player theorycrafting with theirs and that they were sometimes really surprised how close they were to the real ones. 100% blizzlike is practically impossible, we can only be 99,9% blizzlike

[Aasamath]

Damn yeah, i dismissed the idea about frenzy earlier but couldn't figure out how i did before, so i assumed i had make a mistake.
About the ratio ap i wonder that too, it is a different one at late tlk for sure, but i don't know about before.
On the TLK void video, 1/14 works, so i went with it (1374 ap 98.1 dps)
3.3.3 tests on wiki talks about 1/16.28, that's considering the 16% damage increase from 3.0.2

Now for other pet i have yet to find out pictures, 3.3.3 tests show the 0.57 ratio spell power to pet dps is still ok but ap/dps ratio are diffferent, and i don't know if it was already like that at tbc.
Or what is could do is take the ratios listed for 3.3 and revert them using the patchnotes that were applied in beetween.

[Aasamath]

Alright, here's the cc/retail comparison.
First screenshot concerns Gnome Felguard hp pool

INTELLECT COMPARISON

STAMINA COMPARISON

• Base mana and hp of undead warlock is the same on Corecraft an retail (1point off on 1 screenshot)
• Felhunter on CC has 24 more mana than the retail one (2 screens)
• Fellhunter on CC has 9 more health than the retail one (2 sscreens)
• Felguard of a gnome warlock has 10 less hp on CC than on retail. (could be base stats felguard are wrong or gnome ones)
• To do the hp comparison i used 5/5 Demonic Embrace (lowering my sprit). On CC my spriti is 136 base and 129 lowered. On retail they both have 136 spirit already lowered, meaning their base spirit is 142,8 (dunno how wow handles decimal).

I'll continue to investigate this a bit more, like doing the comparison of voidwalker from the tbc video in previous posts, but it seems numbers are very close, so i'll go back to DPS and then mana regen afterward.

EDIT: just did the hp comparison from voidwalker with 610 stamina on pet
9156 hp on retail screen, same on Corecraft ;) so ratio is good

[Aasamath]

I found this spreadsheet but i'm struggling a bit to decipher the infos on the file, maybe someone who's more used to it than me should take a look at it too.
http://www.leulier.fr/spreadsheet/
here's a topic where he answers questions too
http://forums.elitistjerks.com/topic/10050-another-dps-spreadsheet/

edit: there definetly seems to be some valuable infos regarding dps and stats on that one.
edit 2: well here we go
ratio pet/master for stamina, intel, (pet spell/ master spell) and (pet ap/master spell) are ok on cc.

• SUCCUBUS

base stam: 114 (most likely wrong) (257.2 from wowiki if reporter's toon was untalented)
base intel: 133
base ap: 286
base mana: 1109
ratio intel/mana: 10.6

ratio pet ap/damage input: 7/1 (ap/dps: 14/1)

• FELGUARD

base stam: 322
base int: 152
base ap: 286
base mana: 849
ratio int/mana: 4.7

ratio pet ap/damage input: 7/1 (ap/dps: 14/1)
base damage 0 ap: 206
base dps 0 ap: 103
v1.11 of the spread: "FG dps is not correct yet", i dunno if it was fixed at v1.20, using the spreadsheet to reproduce the situation from the gnome screenshot of Mephisto (removing alll other values of the spreadsheet like hit/crit/ glancing blow etc), i came up with 433 dps instead of 395.5
so base stats might be like @Mephisto22 said since they get the right value (verified with spreadsheet).
base damage 0 ap: 148.5
base dps 0ap: 74.25

cleave (max rank): petdamage 0 ap + petap/7+ 78

• VOIDWALKER

base health: 869
base armor: 9070
scale stamina/hp: 13.58
scale intel/mana: 10.6

base ap: 286 (20.4 dps)
base damage 0 ap: 28.6
base dps 0 ap: 14.3
assuming 1/14 ratio which works for 2 other pets, and is often said to be valid for all pet before tlk, except imp. 3.3.3 ratio on wiki is 16.28, after a 16% damage increase in 3.0.2 (14*1.16= 16.24)

• spreadsheet also confirms that soul link, and master demonoligist should be multiplicative,
  paste of function from the sheet (1+sl_0,05)(1+0,04_unholy_po)_(1+md_0,02)

edit 4: some guy in comment says succubus stamina is incorrect.
Also felguard damage on the spreadsheet are similar to that post:
"Base Stats of the FG (I included the base stats of the owner slightly which buffs int somewhat:
350 Stamina (322 without base stats)
195 int (152 without base stats)
Base AP 286
He has a damage range of 178-234, all pets have a 2.0 melee swing speed."
*103 dps seems to be with base ap, so would mean 82.6 with 0 ap, still not the same as Mephisto :s

[netherspite]

Sorry for posting just some observations without any proofs or new research results but I just tested low level warlock leveling and it feels really weird.

I'm not sure whether it's about regeneration or stat scaling but I had issues with my pets.
Imp was regenerating his mana so slow that I had to let him to rest on 1 of 2-4 mobs because he was oom.
Voidwalker was regenerating his health so slow that I had to constantly bandage him (every time the debuff faded) and it was not enough to keep him alive - I had to resummon him a couple of times after he got killed by the mobs.
I'm sure I never had to bandage my pet on retail.

I tried to find videos of warlock low level leveling at Vanilla or tBC times but didn't succeed.

The amount of text/info in this thread seems to be overwhelming, various issues were addressed so here is a summary of remaining bugs that need to be fixed:

pet scaling of mp5 is too high
(they probably use caster's mp5 - I'll verify later)

Felguard base dps (0 AP) is too low

It should be:
74,25 - according to the screenshot (see 2nd post)
OR
82,6 - according to a guy who made a spreadsheet (see 16th post)

The only logical explanation so far is that blizz slightly stealth-buffed Felguard's dps later in BC after 2.0.3 overnerf. Or the guy from elitistsjerks made a mistake.

Dmg bonus from Soul Link and Unholy Power talent stack additively - they should stack multiplicatively
