Thumbs up if you want a spreadsheet that calculates your effective health! Armor discussion is up next!

[@lordcarl3094]

What i do know is that the Armor % is totally fake against Physical attacks in the PvP Zone. I'm not sure why, maybe the % that shows is fake or we only get 65% of our total Armor. Maybe its multiplicative, instead of addictive with diminishing returns that the game doesn't show? Still... i'm much more interested in you talking about Thorns Barbarian, or how it feels when you activate instant death by just putting down a trap. These Thorns are very long, AoE isn't a thing in the game, activation on only hit isn't a thing in the game and Armor is fake, so... What's the point? The max DPS on a weapon barely reach 3000, but you equip Razorplate and you have 11.000 Thorns. This game makes no sense.

Hah, love that.

[@camfrog79]

I was thinking the same thing lmao.. are you a math teacher?

[@dimKiriyenko]

That's an explanation needed to be done! My 2cent: same math, but less calculations when you're choosing between %DR and +HP: * first number is your hp + HP * second number is your hp / (1-%DR) Pick what's higher.

[@Xarrio]

True! Good point. That is another way to do it for sure. One of the reasons why I chose to show it the way that I did is that I'm hoping that people will start thinking about changes in terms of % change. This idea of % change is used everywhere in the game for optimizing your character, from dmg stats, to defensive stats. And once you have mastered the idea of comparing % changes, you can optimize everything as you progress your character throughout the game, instead of just at the end by copying someone else's build.

[@rogueduelist3137]

A huge benefit that wasnt mentioned for DR is how much more effective it becomes with healing.

[@immodsr9348]

That is true, but also HP is better with healing that scales of % HP :)

[@polyento3535]

You also forgot about heal %, for example Rogues, flurry can heal up 15% per hit.

[@sf4603]

@@immodsr9348 you might want to clarify what you men by +HP is better with %max hp healing because its better than nothing but its not better than an equivalent amount of %DR Its true that %DR effects %base healing and flat amount healing where +HP does not but %DR and +HP have the same effect on %max healing If you take his 2 example characters and each receive a heal of 25% max life. The 75% DR character will receive 25 life and the 400 life character will receive 100 life but calculating for effective hp they both end up with 100 effective hp. 25 life with 75% DR = 100 effective hp. So as far as healing goes %DR has some advantages over +HP but +HP has no advantages over %DR. %DR narrows the gap between %max healing and %base healing and +HP widens it without providing any benefit over %DR. If all your healing is %max healing then this difference is irrelevant but we all have access to healing potions which have a flat amount as well as a %max component so at the very least %DR is making your potions more effective than +HP. Should be noted that the same is true for Barriers as well.

[@Miguel-oi8tq]

Crazy how video after video i learn something new and these breakdowns always help me improve my build. Top tier content🤠👍

[@chrissatchel986]

Base on your analysis of effective health between DR & EX HP, they both could be defined as two linear functions by deferent Slope K, defining % increase as Y (y=kx+b). Then they could be equivalent in Y and go down and up.

[@douglosu]

I have always wanted a video like this for someone to explain it to me drawing out the math as they went. This is fantastic! Thank you for this.

[@willceli5977]

DR spreadsheet would be extremely helpful. My question is this: Would the spreadsheet contain other variables such a as Close Damage Reduction, Distant Damage Reduction, Damage Reduction based on how many Dark Shroud Shadows you have how many points are invested into that, etc. By the way, love the content! I love math so seeing how this works makes it a lot easier to make certain decisions 👍🏼 Keep it up!

[@bthorne2]

I think we could do with a video explaining how the EHP changes with multiple sources of DR because it is not reducing the original number, so stacking multiple sources of DR does not always produce a linear outcome. Armor does.

[@umitpalalondon]

Totally agree DR rely on many factors , armor and hp straight forward values

[@KOOKMON1]

I was kind of thinking the same thing. If damage reduction has diminishing returns from multiple sources it seems like you’re adding a lot to the equation then.

[@crumblik]

Love the helpful analysis! EHP is a great way to think about how much we need of Life and DR to survive the biggest hit we expect. For example, if a boss is going to hit us for 50k, then we need to make sure our EHP is at least that, so that healing can take over after the hit. We also need to have enough as a buffer to smooth out damage spikes and allow healing to catch up over time. If we're only expecting small hits which healing is able to cover, then perhaps stacking more DR would be better to reduce the overall amount of damage we take. My 2c!

[@HasturLaVishnu]

I feel like im school and todays lesson is DR vs. Hp :) Love your approach Professor Diablo

[@justemy2516]

good explanation and it might work for a clean character but i believe its way more complicated in lategame base life only increases with lvl ups, additional flat life does not increase with % life and dmg red has diminishing returns except for different sources like dmg red against close / dmg red against elites /dmg red against poisoned etc i prefer life rolls over a 4th dr stat since most classes scale dmg or selfheal with it

[@Binetti816]

Great videos man. I’m glad i stumbled onto you. Looking forward to more videos. Y

[@kinggamerx3xd888]

Wouldn’t the diminishing returns scale the 75% too 62.5% so you would need different dr buckets too hit the hp difference for a 1 to 1 scale

[@immodsr9348]

Was thinking the same, but it is not really diminishing as it always gives 10% damage reduction to the 25% damage you take. That is why he used EHP instead of the total damage reduction number itself.

[@klorinator]

Does the effectiveness of adding life also increase based on your current dr? I would think that if your character already has some dr that should factor into the choice. You discussed base hp but not the effect of your character's current dr when adding extra health. I would be interested to know.

Thanks! Glad you enjoyed it. I actually am using a wacom tablet. =)

[@will160176]

Here's some confusion to add to the equation. Barbs have a talent that adds health multiplicitively. Therefore, adding 1000 health doesn't exactly come out to +1000 health to your new total.... I'm sure I can figure it out by multiplying it first though. And then how do the gems and paragon +health% go into this as well?

[@Xarrio]

Yep. I'm planning a video right now to talk about life %. Stay tuned! It is a fun one.

[@SaintSTXiong]

Can you help explain whether to pick 5% total armor or 10% damage reduction?

[@BeastmanWatchUrMouth]

Did you take into account the diminishing returns of DR stats? For example if you already have 10% DR, that new 10% will have diminishing returns

[@Xarrio]

Check out part 1 of the series where I talk about diminishing returns.

[@clevername1349]

It seems to be much easier to find (relatively) significant HP increases than it is to find significant DR% increases. Something to take into account. At lower levels you will likely find neither a 1k HP boost OR a 10% DR increase. SO, in almost ALL scenarios, it is almost always better to take the DR% increase IMO. Of course the formulas above are great to help one consider what to take if such a choice is available at any given level.

[@Katastra_]

I assume for any build that takes advantage of Fortify and/or Overpower, health would always be the way to go?

[@richardmenz3257]

Life is damage for those builds so think of it as a hybrid damage and defensive stat.

[@kiwi-bird]

Thank you! You have a new subscriber! I love video game science!

[@alexwieauchimmer9782]

Great Video! Im not sure if my thoughts are correct but I think there is another point about damage reduction to think about: For example, lets say you have already 80%dr. Now you have to decie between +10% damage reduction or X more life. the 10% damage reduction would give you from you current state + 100% more tankyness and its verry unlikly to get a life roll that gives you +100% of your current health. 1000 incomming damage 80%dr => 200 incomming damage. 1000 incomming damage 90%dr => 100 incomming damage. from 200 to 100 incomming damage the value got halfed, so it gives you 100% more tankyness. I know the values of 80% dr cannot be achievied, but it makes my point more clearly. Or am I wrong?

[@Xarrio]

The 10% Dr extra won't add like that generally. The 10% DR would remove 10% of the remaining dmg. 80% DR -> 20% Dmg remaining 10% more DR -> removes 10% of the 20% -> removes 2% dmg -> 18% dmg remaining

[@alexwieauchimmer9782]

​@@Xarrio okay ty sir

[@wmpx34]

I didn’t expect DR to scale off max health…I thought it would be current health

[@brunospasta]

This is why I think the "diminishing return" info is confusing people on DR. Because actually its one of the stats with no diminishing return.

[@crizzonet]

Wouldn’t the 2nd hit with 75% DR be 75% of 75 health now,, which would be 56 health after? Or does it always calculate based off the max health number, and not the actual current health number?

[@Xarrio]

Hey, good question. The DR is reducing the HIT not your health pool. The hit from the wraith is always 100 dmg in the example, so the 75% DR will always reduce the hit by 75.

[@SafetyFooT]

My man’s re-rolling starts in VR 😮

[@guirohden]

If you already have good gear with a lot of DR stacked it becomes less effective the more you add, so HP is almost always better. You mentioned that the DR values never change, but they do, if you stack them they lose effectiveness. Let's say you have 50% DR spread across gear, skills and paragon nodes, if you add another 10% from a new gear piece it's not going to be 60%, it will be something around 55% or so. This is why stacking HP and Armor is better than stacking DR.

[@Xarrio]

Check out my vid on diminishing returns and DR, it might clear up some misconceptions: kzbin.info/www/bejne/gn2rqoyidqeLqpI

[@148Reaper]

Having more health also means you need to do more healing in order to survive, saw this quite a few times playing with people that went the hp route when you vs something tough and they keep running out of potions.

[@Jcalcazaren1]

Man you deserve 500k + subscribers

[@Xarrio]

I wouldn't know what to do w/ such numbers.

[@Welcome_The_Revolution]

One thing to consider is that % DR is capped so if you're already getting a lot of DR you may find that you're hitting the cap regularly so adding more is largely wasted. It would be great if there was some in-game stats to display EHP, maybe leveraging your average DR in combat (this will often go up & down as a lot of DR sources are conditional; close, when crowd controlled, for x seconds after using a skill, etc.)

[@Welcome_The_Revolution]

[@RealXBit]

it doesnt stack like that in d4 though. 2 items that both have 10%dr wouldnt be 20% dr it would be 10% then 10% or remaining. so does that make HP better bec of diminishing returns?

[@BigJuris]

I like to use DR all the time even if the hp seems slightly better. because the healing you take from any source is like 4 times more effective. potions have fix number they heal instantny etc. so for me there is no question even to think about more hp if I can take any reasonable DR, resist or block chance etc.

[@firstmarkbannor5266]

That was a REALLY roundabout way to explain a simple concept. 7000/6000 = ~ 16% Damage reduction. 10% DR =~ 10% damage reduction. 11000/10000 = ~ 10% damage reduction and decreases as your life gets higher and higher. It’s pretty simple math

[@bobnewkirk7003]

This is fundamentally assuming that there is no diminishing returns on Damage reduction. I haven't tested it yet, but often times Devs will put a maximum DR value into the calculation to limit DR stacking so as you approach that value your returns on investment drop. Though HP gives less % EH per point, it is is not subject to diminishing returns in the same way so it may well be more effective with higher Reduction values. Its somewhat tangential to this discussion, but Barrier and the Overpower mechanic (if they ever fix it) both play into HP which may also weight the equation towards HP.

[@Xarrio]

From my testing on the tooltip (and searching online), I haven't found any evidence of diminishing returns from damage reduction.

[@UlfhednarTV]

You are a beast man I think damage mitigation is one of the most important things in this game which people neglect a lot. Appreciate it!

[@cixtos]

A breakdown comparing how a skill’s damage scales with level compared to the value of a passive skill would be helpful for crafting builds. I never know when to focus on skill level versus when to go for more points in passives. Looking forward to your Armor deep dive video!

[@maxnovakovics2568]

Depends on your specific build but rule of thumb is. 5 ranks in core skill. 1 rank in other active skills. They usually just apply status for your core to capitalize on.

[@maxnovakovics2568]

For example, I see a lot of Druids put ranks in Trample, but with that build Trample merely casts your Core Landslide, which does the damage. Extra ranks don't lower CD, increase Unstoppable time, or add to the Fortify/Spirit gen. Waste. 4, 8, 12% damage to Nature Magic skills, 5, 10, 15% more Fortify etc are worth a lot more than putting ranks in Poison Creeper either. You only want Creeper for the 20% crit chance, apply the "Poison" tag to enemies, apply the "Immobilize" (which is also "Crowd Control) so your "+% dmg vs psn", "dmg vs cc" stats are getting used. No Druid build is stacking Poison dots like a Vanilla Warlock in 40 man Onyxia 😅 My friend had 5 ranks in his basic skill, and in Blood Mist saying it does more damage that way.. "Brother you can do more damage with the Bone passives. Blood Mist is just a panic button, not an attack..."

[@Xarrio]

Glad the vid was useful so immediately!

[@NinjatasticEspy]

Doesn't the value of DR % also depend on the possible damage incoming? Like in a dungeon let's sum up 3 mobs types. Norms, Elites, Boss. Norms hit 100, elites hit 300 and boss hits 500. Flat health isn't beneficial with all types where DR is more beneficial the higher the incoming damage is.

[@Cymricus]

it’s impossible to calc effective health in diablo 4 the way they spread different types of DR, resistance, and armor across stats unless you’re looking at strictly the stat “damage reduction,” which is only one of the several mitigation stats the way DR really works can’t be calculated as it depends on a dynamic system - what type is it, where is it when ability used, is it environmental or from a mob, do you have buffs, etc. it’s just way more complicated than it seems and there’s no calculation that’s gonna help

[@johnmichaelarnaud]

This was my only question as well, as DR in the game is so often conditional, it seems nearly impossible to calculate any kind of static amount for comparison.

[@heikojohnmoller7853]

so what is the result? What is better hp or dr ?

[@alirawidduh166]

Adding DR, your life moves up and down in a more predictable way than in adding extra life. This is important in hardcore, where you want consistency in your "hp movement".

[@bullseye608]

They're both EXACTLY the same. Neither one causes your life to move up or down more or less predictably...

[@jfeb2822]

[@Asgardinho]

[@WardenDios]

There's got to be a formula to calculate exactly how high a life roll on a piece of gear has to reach to start outclassing a DR roll for more Effective HP, given your current HP as a static data point. So if you're at the Occultist rerolling a piece of gear you know exactly how high you want that life roll to get before you stop re-rolling over it for a higher value.

[@daemonkisure2952]

.

[@LFC608]

I'm having a similar issues deciding between raw HP and extra dodge chance. I'm just keeping one in my stash until I learn which is more worth having.

[@Xarrio]

Good question... dodge effectively works the same as DR in terms of the average damage reduced. For example, if you had 50% dodge, then you would take 1 out of every 2 hits on average. Versus if you had 50% DR, then you would take half the dmg every time. Well half the dmg for 2 hits (for the DR case) is the same as the whole dmg for 1 hit and 1 dodge (for dodging). Generally tho people don't take dodge over DR because it is inconsistent. You either take 0 dmg or all of the dmg. And if all of the dmg is more than your health pool, you are dead. Versus taking half of the dmg each hit, you then have time to heal it up before the next hit hopefully.

[@crackityjoe]

If I have 20% damage reduction from close, as well as 20% damage reduction from distance, is that the same as having 20% damage reduction, or is some other mechanic where an enemy can not be either close or distant, such as if they are exploding or affecting me after their death?

Are you a teacher/ professor in your day job? You are very good at breaking down and explaining concepts

[@haydenap]

Isn't 10% DR only ACTUALLY 10% DR if you don't have any other sources of that kind of DR? If you already had one piece of gear with 10% DR, and then you add another piece of gear with 10% DR, that makes the second piece not as valuable since both DR rolls will multiply together, right? 10% DR means you're taking 90% damage if you have two, you multiply 90% by 90% which instead is 81% damage taken. Or 19% DR. Or am I just completely wrong in my understanding of how this works? Doesn't that make your DR change in EH formula not work?

[@Xarrio]

You are correct in how the DR calculation works. However, you are incorrect about the 2nd 10% stack being less valuable. While it does give you 9% more DR, which is less than the 10% DR from the first stack, the 9% increase in DR from the 2nd stack actually ends up being more valuable in terms of your ehp total. I explain this in my 1st video in the series: kzbin.info/aero/PL5GXa9pP7xwVf7V6K4Xh55s6nU8W7XBC9 But, the ehp in both cases increases by 11% from 1 stack to the next. Try calculating your ehp with 1 stack, 2 stacks, 3 stacks of 10% DR, then find the % change in ehp from 1 stack to the next. You will see it is the same.

@@Xarrio thanks for the reply! I ended up watching your DR series in reverse and found this out after I commented. Nice work! I definitely learned something about how DR works. Looking forward to seeing what you make of armor. As far as I can tell there's no easily identifiable formula for it.
