Thumbs up if you find the spreadsheet calculators helpful and you want more of them! Feel free to leave your questions in the comments below. I try to get to as many of them as I can. Your questions help me come up with ideas for futures vids so def keep them coming! Also, the record for this DR series is a bit over 1500 likes on one of the vids, so lets see if we can smash that.

I wish you streamed, or have a way for us to Q&A with pics e.g. equip comparison Qs. And also a way to support you some way via donate channels. Let me know! I've gone with RF knowing very well it isn't meta but was just something I enjoy. Now, I enjoy + actually shred stuff and push higher NMD and not get 1 shot anymore thanks to you!

When I had topaz's in my gear my friend was baffled by my choice where as he was sporting all rubies. Told him usually if I die it's because I can't get away and was CC'd and these seemed to consistently keep me alive and were noticeable when I was for example...frozen. Glad to see the math supported my choice for my situations.

[@mikeperez8]

Exactly this

[@Kirb80-l6r]

One thing to consider is topaz doesn’t do anything unless your cc’d. Rubies give life 100% uptime..for instance if my rogue has 50% dodge and the required armor/dr paired with an unstoppable (shadowstep) on a 3 sec cooldown, and that’s not even mentioning all my cc capabilities…I’ll take the extra health for those tier 100 dungeons personally.

[@im7254]

remember that any slow or even chill counts as cc. those are even on nightmare affixes you can go for. return wise dr is easier on gems and hp is easier on paragon board

So my builds with only one unstoppable I use topaz. When I have 2 unstopables or able to keep up unstoppable 100% of time I use rubies. I am glad my assumptions was right. Thank you for doing the work to prove what I felt.

[@im7254]

there is a common affix for nightmare dungeons that distant enemies apply slow to you which means it's virtually always up.

[@romainfevrier3493]

I would like to add one little detail. When we are fortified and take a hit. We loose fortify. So I personally choose sapphire just because having more DR = loosing less fortify from each hit. If I choose rubies, maybe it can be a bit more effective in my setup. But I will have more trouble to sustain my fortify status

important to note that barriers are based off of health, so ruby bonuses are bumped up for a sorcerer who is constantly popping new barriers.

[@ashyguns8669]

My fiance doesn't even know that she's in competition with my love for your videos...

[@ManxVikingUK]

One thing i noticed was the rare paragon nodes that give the extra bonus to max life count seperate, so instead of 8% it counts as 2 sets of 4% which nets a little bit more life. I could be wrong, but i think this tallied more with the values i saw in game. On barb some of the paragon set ups can net so much life%, combine that with upgraded challenging shout with increase duration from crowd control duration for extra near perm 20% and a fort potion for 30% and you're easily past 30k health. Just imagining this with a Doombringer if anyone ever finds one, can roll up to 41% max life, that'll be one chunky health pool. It gets to the point where 2% health nodes are almost as good as having a mid max life roll on gear.

[@TylerKrantz-m8x]

I'm a low vision gamer, I appreciate you reading the equation aloud. Thank you!

[@AznDumbum]

And DR applied onto the additive HP as well. Also, the potions only heal you of a set amount, therefore each potion is more potent with the DR you get for your EHP

[@Professor-Slothmaster]

Great vid, thanks! I did some algebra and came up with this rule: There's a breakpoint at 2653 * (1 + multiplicative life bonus) If your total life on gear exceeds that breakpoint, sapphire is better. Otherwise, ruby is better. For example, in your vid, you have 53.89% multiplicative life bonus, and 2903 total life on gear. The breakpoint is at 2653 * (1 + 53.89%) = 4082.7. Since 2903 < 4082.7, ruby is better for you. Sounds about right?

[@exnexe]

one interesting thing with barb is enhanced challenging shout, it gives 20% bonus maximum life, this is applied to base health before other multipliers, like 15% from imposing presence or paragon nodes

[@BeastmanWatchUrMouth]

Rubies seem better overall since the extra health is always there, whereas the DR while fortified isn't guaranteed (you could be not fortified of course)

[@Arkayjiya]

Fortify can get much better depending on your healing source. If you rely more on potions (which has a fixed component) and other fixed healing boosts, then your EHP might be slightly lower, but your healing in percentage of your max health will be much greater with fortify. If you rely on % max life healing then both are affected the same way and rubies are as you said more reliable.

[@eos985]

Informative video. On the spreadsheet, would it not need to know non gem sources of fortify DR in order to calculate the EHP that sapphires add? I if i understood one of your other videos correctly, all DR sources apply multiplicatively like +% health effects do. Cheers

[@thomasvandervliet9387]

Just list your deaths and find out on how many of them you were under a form of cc. I think the percentage is huge and topaz is the way to go. Think of spiders, ice walls, slow tornadoes etc. In practice you will take a huge percentage of your damage and deaths while cc'd.

[@Ray-yz5wd]

@@thomasvandervliet9387 I think death stats would be skewed towards how novice players die, and there’s also a difference between SC and HC playstyle where HC players tend to be more balanced with more defensive skills (CC breaks) while many SC players may forego defensive skills altogether. And imagine the stats for HC players where you have 0 deaths from me with closecalls while not CC’d vs new players dying constantly at low levels for one reason above all; inexperience.

[@marcoonroad7]

I've made some tests and rogues have at least 2 CC-skip skills, the shadow clone and the skill where rogue conceals himself/herself, both make rogue immune to CC for a short time, pair it with the protective bubble aspect and the boot/mobile aspect making the character immune to CC if previously hitted on CC, so we have 4 key options to avoid being killed on CC

[@rhaegoti]

Great video! Could you also do a comparison for gem choice for weapons? Very new to the game, not sure if there is a clearcut winner for everyone, or if certain builds/classes favor certain gems.... Thanks for any help :)

[@Z0mbie432]

I will never get sick of hearing someone do the maths for me thanks brother

[@Lakiozoon]

So for a Barb with lower base life (aka leveling like 60-80 for example), sapphires would be the better option? Sub 14k life with rubies and paragon should be the rough breakpoint?

[@arosiah2338]

these diablo math vids have been a huge help for me

[@Xarrio]

Glad that they have helped!

[@drakedbz]

The other thing you don't mention here is that EHP isn't necessarily equivalent between DR and HP increase. A larger health pool means any healing that is based on your health total goes up, whereas more DR makes flat healing values better. In other words, take a look at where your healing comes from, as that may make one form of EHP better than another.

[@vormarsch]

I can't find the entry on my character stats popup for DR while CC'd when slotting Topaz (the other 2 categories for DR no problemo). Is that the same "hidden stats" weirdness as with some stuff not showing up from Paragon boards?

1 question, dont crucify me i bn outta school for AWHILE. When multiplying the max life multipliers %, why is it 1.02, 1.04 etc, instead of .02? is the 1 a placeholder? u mentioned it in the vid but i didnt understand why.

[@knicklichtjedi]

Thank you for Darkmode "White"board!

[@rooseduece]

My understanding is that barrier scales with your maximum life (but cannot exceed your base life). So, if that's correct, then would Rubies somehow contribute twice to my EH (i.e., first to my barrier which scales off of my max life and second to my max life itself)? I've been digging these videos, learning a ton and making adjustments to my build. Thanks for all your hard work.

[@Xarrio]

I'm not sure how barrier scales with other classes, but I know for temerity pants, it only scales with your base hp. But also remember that DR% also affects your barrier, so if you are thinking that your barrier increases your ehp twice, your DR% also does the same thing in effect.

[@KC-tm2jq]

Just watched and had the same question. Thanks for making diablo a learning experience as well as fun! 🎉

[@rooseduece]

@@Xarrio I'm basing this on what I read about barrier at Maxroll GG, "Since nearly every Barrier scales with your Maximum Life ...". But it says 'nearly every' barrier so perhaps Temerity's barrier is one of the exceptions. Regardless, your point about DR still stands, any DR or life would contribute to EH twice with barriers. Thanks for the reply.

I started to use skulls for healing recieved. At first I had plenty of sources of dr, ways to get out of cc but my health recovery was lacking so I would runout of potions.

This kept me alive longer against stuff like poison.

[@kydelastra]

They aren't talking about LPK, but the healing bonus given from placing skulls in armor.

[@WardenDios]

So, long video short: If you have lots of paragon nodes that give +%Life, then use rubies in your armor, but otherwise, use some form of Damage Reduction in your armor.

[@TheVic18t]

Define “lots”

[@Batboy_915]

No, because the DR is situational. For sapphires, you have to be Fortified. For Topaz, you have to be under the effects of a crowd control. If you run out of life you die, so the best bet is still to try to add as much as possible to health.

[@Imorteus]

its almost this simple, but not completely. DR make healing stronger as well which you should take into account

[@TheVic18t]

@@Batboy_915 no, did you watch the video? If you’re getting 1 shotted at high NM, there’s no amount of health bonuses currently that’ll change that to getting 2 shotted. Especially when CC’d you’re going to get hit multiple times. With Topaz that at least changes it to surviving 2-3 more hits.

This bolsters an argument/debate that using rubies after u have deeper para investment becomes more valuable since u stack all those little multipliers… that’s if u are wanting to stack life vice DR or other thus being cognizant of when to swap over.

[@g3synth205]

Have any of your videos covered a comparison between how debuffing a mob's damage works compared to increasing your personal damage reduction stat? There's a passive for Barb shouts that lowers a target's damage output by like 12%, and then there's an ability for Druids as well (Hurricane) that lowers the damage output of targets affected by Hurricane by 20% (the Decrepify curse for Necros also does something similar - there are probably other abilities too for other classes). Is that the same as 20% DR, or is it superior, inferior, ?

[@Xarrio]

It works the same way as far as I know. The difference is that if the mob is debuffed, then it helps out your party too instead of just you.

[@TheWizzkid67]

Loving the videos man so much good information. How about rubys vs diamonds in armour for sorcs with all the barriers they have.

[@Oni_Ji]

So damage reductions percentages of the same type e.g. "Damage reduction while fortified" are not additive with each other, but are multiplicative? So for example, you have two affixes with 25% "damage reduction while fortified" and one affix 25% "damage reduction from close", your total DR would be 1.25 * 1.25 * 1.25 and not 1.5 * 1.25?

[@Xarrio]

They are multiplicative, but not in the way you multiplied them. It would be 1-(1-.25)(1-.25)(1-.25). Check out my earlier vids in the series to understand how DR gets calculated if you'd like.

[@sol5916]

I never understood the craze around life. Life matters if time to kill is short, but where survivability actually matters is high nightmare tiers where things take a while to die. If you can’t sustain through DR, it doesn’t really matter how much life you have. It’s what we learned from trying to use the temerity pants

[@Xarrio]

Both matter. Temerity pants aren't bad because they give barrier, they are bad because the alternative are pants that give a TON of DR that way outweighs the extra barrier.

[@L2DA41]

Life literally helps with that goal though and just a nice stat overall - As a casual gamer I went with rubies coz it just applies 100% of the time.

[@ole5837]

i guess also one note if u have barrier/fortified that will also be higher so you kinda get "dubbel" value from % hp gems

[@GhostlordGames]

Even if Rubies get beat out, is it worth considering that they provide HP 100% of the time, while the others provide DR only when you are either fortified, or when you are CC'd. So if its close, I think Rubies are better.

Rogue aspect synergy question. Aspect of explosive verve makes grenade skills count as trap skills. Aspect of surprise makes you drop grenades when you evade. Do those dropped grenades from aspects like Aspect of surprise proc trap mastery perk? Or no since the dropped grenades are not a skill, but a byproduct of an aspect? Has anybody tested this?

Bro the CC damage reduction trumps everything on armor u less your class can unstoppable constantly and even then. Sometimes you dash or roll out of a sticky station into another one because there just isn't any place to roll or dash too. Having 50% DR during CC (I doubt it's actually that high) beats everything else.

[@SillyMonkeysLikeApples]

CC its pretty powerful when its applied to you, those freeze and stuns last forever! I may go full topaz

[@HeberLopez]

Are you taking into consideration their diminishing return implementation for damage reduction? It’s my understanding that %dr on stats does not mean actual %dr since the effective %dr is lower but I don’t have that particular formula to have into consideration. For example if you have 20% fortified dr on chest and pants you’ll see on you stats sheet that it does not show 40% but rather a lower number since even though for the same type of dr is additive, the more of that stat you have the less effective % reduction it actually gives (although it still scales because of the way damage reduction in general is implemented as you explained on other videos for armor for example)

[@Daniel-rd6st]

One thing i have wondered, how does the game calculate different kind of DR? For example, when i have a character that has a DR vs all of 10% and 20% DR when CCed and lets assume that the character is CCed at the moment, do those DRs get multiplied together, like you have shown, or are they treated seperatly and the incoming damage first goes through one DR and then through the other?

[@Xarrio]

In your example, while CC'd, you would have DR vs CC and DR all applied, which would work multiplicatively. DR%Total = 1-(1-20%)(1-10%)

[@Daniel-rd6st]

@@Xarrio Thanks! First i thought that cant be, because it is not too difficult to get to 100% and more DR, if the game calculates all different sources of DR multiplicative but then i remembered that i think the devs said that there is a hardcap for DR i think at 80%.

[@Xarrio]

@@Daniel-rd6st There is no hardcap on dr, or a softcap for that matter. Maybe you are thinking about the hardcap for DR from armor specifically being 85%.

[@Daniel-rd6st]

@@Xarrio Ignore this post. Are you sure about that? Because it is not too difficult to get a DR for specific Situations above 100%, especially when you are control impaired with topazes. For example my character at at a time around 36% DR against close enemies + 5 perfect Topaz + around 10% DR when fortified + general DR from the boni on the armor at around 10% + around 15% DR vs distant enemies (i think, it has been a while since i went for heavy DR). So basically when control impaired it shouldnt have been possible for an enemy to kill me at least in close range and yet it did happen, i dont think that i ever was invulnerable. Or am i making a mistake here? Or does that 85% hardcap trigger here, that you mentioned? Because i dont know exactly what you mean with DR from armor. From the boni on the armor or the DR you get from the armorvalue?

"Damage reduction"(DR), reduces the damage you wou take from an attack, "enemies deals less damage"(EDLD) reduces their damage output and it stacks. Examples Enemy deals 100 damage, you have 20% DR You take 80 damage Same situation but (EDLD) ENEMY deals 100 damage but you reduce their damage from 100->80. Now if we stack both, DR and EDLD Enemies damage drops 20% 100->80 Then you have 20% DR 80->64 What makes this nice is EDLD works for your whole party. Example rogue "Poisoned enemies deal less damage" helps everyone not just the rogue.

@@razgriz2276 ah, the party thing makes sense then. I always play solo so I didn't consider that.

[@razgriz2276]

@@JukeStridewalker always happy to help. 👍This calculation works for "you Deal (x%)more damage" and "enemy takes (x%) more damage" and actually makes you deal MORE damage then just doing 1 or the other. Example Your damage 100x20% increase 120 Enemy takes 20% more damage. 120x20%=144

[@sinitarpku]

I saw it somewhere that, instead of multiplicative, the default 10% DR by fortify is additive to the "DR while fortified" stats which means the more "DR while fortified" you have, the more effective this affix gets. If this is true, then stacking Sapphires may be good for some people. I haven't tested it so don't quote me on that.

[@Professor-Slothmaster]

I've been trying to find a reliable source to confirm the way DR w/ Fort works... If it's all additive, the max total DR w/ Fort = 105.25%. wtf? Base DR w/ Fort = 10%. +3 Defensive Stance = +6% +6 Sapphires = + 6 * 3% = +18%. +3 affixes = 3 * 15.75% = +47.25% +Undaunted = +10% +Bulwark in Bone Breaker = +14%

Another excellent video. This might be my favorite one yet. Originally the gem meta was full Rubies in armor because they give the most obvious benefit for non Druid/Barb players. But then a couple streamers started running full Topaz and then everyone and their mom started copying them. But your video clearly demonstrates how at least for Rogue that has even a pretty minimal investment in max life in the paragon board Rubies are the best option unless you aren't running a CC break like Shadow Step for the unconditional HP it they give. There are A LOT of maximum life nodes on the paragon tree. Combine those with Rubies and 3-5 life rolls on your gear and you can get between 16-20k HP which is a fat health pool. I currently have 17311 hp, with 4 life clusters on my tree (8x 2%, 4x 4%), and 4038 health from 4 slots of gear. I gain 2363 life from my 5 Rubies. I'll take that any day over the conditional Topaz DR. I run two charges of Shadow Step so I should pretty much never be perma CC'd in the first place. There does appear to be something wrong with the spreadsheet for me though. I plugged in my total life with rubies, adjusted the paragon part to include all 12 of my paragon life nodes, I plugged in my life on gear. But it's showing that I should have 13363 health without Rubies, but when I take out my 5 Rubies in game I only go down to 14948 health.

Thanks for the feedback. That is odd on the calculator. When I test it, it comes out correctly. Are you sure you are using the correct section? One section is for going from rubies to no rubies and the other is for going from no rubies to rubies. Anyone else having it come out correctly or incorrectly?

[@haydenap]

@@Xarrio Am I meant to interact with both sections? I may have misunderstood your directions in the video. I thought I only needed to interact with one section. I can try again and see if I get a different result.

[@Xarrio]

@@haydenap Yes, you only need to use 1 section, but you need to use the one that applies to your situation. If you have rubies equipped, and want to know your base hp/ehp, use the top section. If you have them unequipped and want to know, use the bottom.

[@exnexe]

can you make a calculator sheet with armor included?

[@chiefkikyerass7188]

Live your videos...could you explain crit chance..example..crit chance on gloves and crit chance to injured on gloves..does it stack or we uts going on there?

[@Xarrio]

Thanks. Good question. Crit chance adds to crit chance when injured when the enemy is injured. So if you have 40% crit and 20% crit when injured. You have a 40% crit chance when the enemy is above 35% health and 60% when it is below.

[@mowtow90]

A very important factor in choosing a gem is does it give resistance? If it does - ignore it. Resistances do not work ! Its officially confirmed that only armor and fortified stat work. I dont know how did they sc***wed this up but and entire system in the game doesnt work. This is why the sorc is a glass cannon , because its main stat (int) gives resitance and that doesnt work.

[@ooanticsoo4475]

Funny enough I wonder what interactions are considered cc. For instance ww barb you are actually slower when channeling. But if you use an unbreakable shout you actually move faster while channeling. I wonder if the 2nd is considered you putting yourself into a cc state.

[@dozegamin8604]

Own effect is not cc.

[@scaroz2749]

Topaz is best for fast running Dungeons, where you don't pay to much attention and get caught in some kind of cc. When pushing, you don't want to get hit by anything. So there are better options.

[@daemonkisure2952]

for necro what is the best?

[@Pall_Bearmasher]

Well some builds on Druid are constantly critting and healing so you are barely fortified because always max health. I use rubies
