[Game mechanics] Guide to damage, tenacity, reisistance and debuffs in Neverwinter

Greetings.
There have always been a lot of game mechanic questions and misunderstandings in discussions as we seek to better understand stat/ability effects and optimise our builds. I've compiled much of current knowledge and my understanding into this guide on Neverwinter mechanics with the aim to break down information silos and discuss the concepts in a clearer way than that gleaned from in game tooltips.
I don't have any more access to privilege information than the average player, and I am aware that some of the equations and formulae are at best a good model but in absence of developer information this is as good as we know of how things work.

Introduction
A well built character in Neverwinter seeks to maximise outgoing damage and minimise incoming damage in particular scenarios. Different scenarios (eg PvE vs PvP, trash clearing versus boss, AoE vs single target) inevitably calls for different stat distributions, but at the crux they all depend on an understanding of combat damage mechanics.
Since Neverwinter has a large number of stats, players can easily get lost trying to understand, let alone optimising their stats for PvE and PvP. This guide will walk through the mechanics of Neverwinter combat damage calculations, focusing on the following topics:
Relevant stats for offense and defense
How damage is calculated in NW in PvE and PvP
How armor penetration works vs damage resistance
How effects of buff and debuff abilities are factored by the game engine in PvE and PvP
What tenacity does and its effect on resistance.
I am not going to straight up say how much stat you should put here or there, but I want to dissect how damage is calculated and in turn help you realize what stats to focus on. I want to make this guide largely standalone, so apologies to my readers for the slight overlap with my DC guide and Power vs crit guide.
Some of the formulae for this guide have been sourced from the Neverwinter forums and verified for accuracy and relevance. The rest of it comes from hours of personal data gathering, testing, model fitting and analyses together with discussions from fellow players and number crunchers. Thank you to all of you who have contributed to the pool of knowledge we have. If there is anything I have misunderstood or you have any additional data or theories on the concepts presented, your constructive feedback on topics discussed is most appreciated.
I'm happy to keep the relevant discussion here, but as the guide have a large number of images, equations and links, and will be updated as things change the rest of the guide is hosted at

I love it when people actually do real tests and comes back with real numbers, solutions and up to date information. Most of the things are not up to date in neverwinter
For me personally this is the best guide I have seen in a long time and the best guide of any neverwinter guide. Explains everything to the bone. Thank you!

Thanks for all of the hard work that went into this guide.
Just a thought.
and is that really about 30%??
thought it would buff encounters as well ...

E.g.increasing the crit stat from 1000 to 1100 will increase the crit chance from 8.09% to 8.78%. Assuming default critical severity of 75% this increases the damage multiplier from 106.07% to 106.58%. That is a relative increase of 0.482%. In your graph the increase is about 0.53%. I don't understand the difference.
To be more precise here's what I'm doing:
1) Crit chance is calculated using 0.288 * crit^1.2 / (10185 + krit^1.2)
2) Damage multiplier is calculated using 1 + severity * chance
3) Relative damage increase is calculated using (afterDamageMultiplier - beforeDamageMultiplier) / beforeDamageMultiplier
1. Calculate crit chance with similar formula (I have the +0.05 term in there but doesn't make a difference in this case)
2. Calculate crit % difference every 100 points
3. Calculate DPS boost = crit chance difference * crit severity
For example at 1000 crit chance is 8.14 and at 1100 chance is 8.82%. Difference is 8.82-8.14 = 0.68% * 0.75 = 0.51% DPS increase
I did discover that my x axis is shifted by 100 because I started at 100 instead of 0, so the corresponding value should be ~0.51% instead of 0.53 (that's the value at 900 crit) and I'll fix the graphs in the next update.
Results trends are the same between our methods, shown here for 75% severity (yours blue, mine red), but the corresponding cut offs would be of course slightly different. If anything the percentage increase method makes crit even less desirable.
The percentage increase method makes a lot of sense, however I am reluctant to use it as comparison because percent based results will vary depending on base crit chance from feats and ability scores (in our example we are assuming 0% base crit, if you have say 10% base crit those values will decrease a bit). This restricts the general applicability of the result, whereas my method allows the DPS contribution value to be determined from crit strike directly. Let me know if you have further thoughts on that.

Could you expand on something though? About the blink dog's active bonus..
"In particular the blink dog’s CA damage bonus does not seem to follow the above equations and appears to decrease your overall damage (at green rank, not sure about blue and puple). Again, happy to hear more from others. This is my knowledge gap."
Are you saying that it actually decreases my damage output or do you actually mean that it increases it at a diminished rate?
I mean, should my crit-heavy, CA oriented TR stop running with his blink dog?
I will certainly try with/without and try to see for myself, but I'd love to read what you know or observed about this.
Thanks again.

If you are already working at it or not i would like to know whether you are testing other stats such as control bonus etc. atm .
From my tests, on HR with aspect of pack with 150 attacks each comparing damage with and without blink dog and with/without CA damage, having the dog (green, have to repeat with blue and purple) in the active slot actually decreased overall damage compared to having no blink dog. I have yet to repeat the test to confirm. However I have spoken to various others who actually tested and mentioned it either had no significant difference, a slight increase, or a dramatic increase. If others have concrete data and parses I'm happy to hear of their experiences.
CA data is hard to get because of the following:
-It's a damage buff, so you can't directly quantify bonuses from brackets or ACT, and requires large amounts of data points for it to be statistically different
-Any bonus from skills/feats/ party members which buffs your damage will immediately invalidate your data. Even if someone runs in and only attack your target dummy for a few rounds can invalidate 5-10 minutes of testing because you don't know which attacks to exclude from logs
-It seems to interact unexpectedly with crit severity which mean you must split crit and not crit damage in calculations
-Any CA bonuses are very slight, especially as they seem to only boost the CA portion of bonus damage, and not your base damage
-CA damage only procs reliably on HRs with Aspect of the Pack, other class only benefit from it occasionally which means you need even more time for testing, likewise with TR stealth.
It's just hard to get any real field tests done I am hesitant to give any definitive advice on whether it's worth it or not without concrete evidence. In my opinion the bonus by itself would be too slight to notice without deliberate parsing.
@ryugasirius: Black Ice damage (Black Ice corruption in logs) bypass current defense resistance however much you have and deal 100% damage to an characters without black ice resistance. If you have black ice resist then
Black ice damage dealt = base damage * (1- black ice resist %)
@cromejohnsen Thanks for the suggestion, I may update it when I have time. Right now I have no plans to check control bonus for PvP because I don't think I can achieve the precision of duration down to tenths of seconds given my high ping. I may look into it for PvE though it may already be fairly well established. Incoming healing is already established. Combat advantage is a mystery due to reasons mentioned above. Action point gain bonus is multiplicative with that from stats/recovery. I will expand and include in the guide

I ran some tests with the blink dog using a CW. Basically, I would use Nightmare Wizardry as my Combat Advantage trigger. I would throw a spell at a dummy, if Nightmare wizardry triggered then I was guaranteed that my next spell would have Combat Advantage bonus. So, doing lots of tests with and without the blink dog I found that damage increased on non-critical Combat Advantage hits by 1.5%. Damage on critical hits did not change with the blink dog equipped. Statistically, my margin of error would probably be a few percentage points either way (so Theosymphany's results are likely within my margin). But whatever the reality is, I'm highly skeptical that the Blink Dog is worthy of an active companion slot no matter how much Combat Advantage you employ. I dumped mine immediately after testing.

Thanks for the explanation. That clears things up. Taking base crit percent into account makes critical strike indeed even less desirable. IMO it needs to be taken into account when trying to find the "optimal" balance between power and crit. For an easy check it is too much of a hassle and in the end may not make that big of a difference. Especially since one cannot arbitrarily shift points between power and crit.
Another thing I noticed is the 80% DR cap you were referring to. You said the DR is capped to 80% before taking resistance ignored into account. I remember a dev's post where a formula was given showing that the 80% cap is applied after RI was subtracted.
Unfortunately I cannot find this post anymore.
So for calculations of damage, it's already established if attacker RI is > defender DR then RI = DR so it doesn't go negative.
Converse if DR-RI > 80 then DR = 80 due to the cap.
Even then, as DR is a hard cap, whatever the damage calcs pan out post RI, if the total DR ends up being over 80 either from buffs, tenacity etc its still going to be capped at 80% The only thing that can further reduce damage at that point is either dodge/immune/special effects like GF artifact or deflection. Now I'll need to work out how to incorporate that in the formula...hmm
so more like
Effective damage = base damage * buff and debuff effects * (1+ total RI + total DR bonus/debuffs) * (1- TeR)
IF total RI > total DR, total RI = total DR
IF (1+ total RI + total DR bonus/debuffs) * (1- TeR) < 0.2, (1+ total RI + total DR bonus/debuffs) * (1- TeR) = 0.2.
Crits (and TeR crit damage reduction), debuffs and deflect can still apply on top of that multiplier.

So, having any defense in IwD is pointless, unless you are doing PvP, as all mobs do BI damage... is this correct?
No. From my experience monsters do black ice damage in addition to "normal" damage. Also it seems not all monsters do black ice damage.
In the skirmish Kessel's retreat black ice damage can account for over 50-60% of overall incoming damage, and without well timed prones/freezes the party can semi wipe quickly even with black ice resist. That said, in a geared/experienced party you'd have no issues at all swapping back to regular armor (I still use HV on CW and HP on DC) if you're timing controls well/killing fast/ focusing on casters first.

got a ton of new information.
apparently the new greater corrupt black ice enchant which u can slot into your new black ice gear (the blue sockets) can proc at the same time and have approximately a 1 min CD. Same CD goes for the black ice gear set effect.
For the black ice set weapon effect it will show 2500 dmg in blue color when it activates and seemed to proc around every half minute.
For everyone who is interested the last boon in IWD which gives u 500 extra dmg on heal , it only procs when healing yourself.
That means lifesteal does not proc it . Tested it . When it procs theres a lil buff icon showing up on your buff bar . It has an internal cd of around 1 min as well.
I don't have much but I would like to donate some ADs to your hard work and would like to encourage others to do the same. This guide will be invaluable to pros and beginners alike for as long as people are playing the game. Please let me and others know how we can show our appreciation.

With lots of testing and data collection by @angrymanagement I've managed to recalculate all the combat advantage formulae incorporating the new bonus and updated it in section 2.3. Because some of the bonuses are quite small they fit both an additive and multiplicative model but right now this is the best take with the data I have.
CAbonus refers to the auxiliary bonus % received from boons and artifacts
CHA bonus gives 1 % bonus damage per point over 10, i.e. CHA bonus = (CHA-10)/100.
Equation 2.3. CA damage calculation for non crit hits:
Total damage when CA is granted = base damage * 1.15 * (1+ CHA bonus%) * (1+ CAbonus %) * (1+ blink dog %)
Equation 2.4. CA damage calculation for critical hits:
Total damage with CA and CRIT = base damage * (1+ 0.75 + sum of all crit severity bonuses + 0.15 + CHA bonus + CAbonus) * (1+blink dog %)
For example
Say I have 18 CHA (8% CHA bonus), CA bonus of 400 (converts to 4.9% from section 1.4), a purple blink dog and only base severity of 75%.
CA damage (non crit) = base damage * 1.15 * 1.08 * 1.049 * 1.05
CA damage (non crit) = base damage * 1.368
You do 36.8% extra damage with CA
[edit: left out 0.15 from equation, thanks to pengustrike for pointing it out]
CA damage (crit) = base damage * ( 1+ 0.75 + 0.15 + 0.08 + 0.049) *1.05 = base damage * 2.029 * 1.05
CA damage (crit) = base damage * 2.13
Given that the base crit damage is 1.75x, this is an approx 21.7% increase boost with CA over a standard crit hit.

HR with AotP get 85-99% CA quite easily with their hits when played well, that's theoretically 0.85*5 = 4.25% damage bonus from one pet and surpasses most other ones out there.
For GWFs with a decent party if you estimate 30% CA uptime that's 5*0.3 = 1.5% bonus, which is still better than 300 power (~1.3%) and about on par with dancing blade. Of course with module 4 if Mark mechanics grant CA then CA uptime would be quite a bit higher and raise blink dog's bonus further correspondingly.

It seems to have the same active bonus.
PS is there some guide on which companions are the biggest boosts too damage? I've tried the one on the order of the raven forums, but it seems kinda limited :<
