Who's feeling lucky?

I love the way you explain things, it's like you're speaking to the lowest common denominator which ensures everyone gets a very thorough understanding. Would you mind doing a short video like this for Fortify and Overpower - I feel like those are fairly complex stats that are frequently misunderstood.

What kills me about the system is when it's a double percentage. Like having 10% chance to activate something on lucky hit... so it's like 10% of 10%. That just feels worthless and is an insta skip skill every time for me.

there are some cases were it gets more complex for example: "luckyhit: you critical strikes have up to a 5% chance to do X" shouldve explained those as well

Thanks for breaking that down. It'd be nice if the game explained all this stuff more clearly. They should be able to explain it in game as simply as Raxx did here.

Just what I needed, you are doing really outstanding videos and explaining so good, not to mention the efforts for the art works :) Can you do another one explaining the "overpower" mechanics and how that works?

And THAT is the explanation on why lucky hit was implemented but not exactly how it works. I think most people will still be confused :D

The first example would have been more effective using a flat damage value. Multiplicative scaling just aligns with the scaling of the skill itself. That HotA would hit real hard lol.

Thanks for the explaination! At least D4 is clearer with proc coefiicients for skills compared to D3 :D

Tanks for putting this on youtube, I don't really watch streams a lot so it's great having this kind of info curated here.

You know it is getting serious deepdive when Rax takes out ugly paint and writes with mouse. Most professional.

Thanks for the explanation, been struggling with all the new terms in D4 but feel like I´m starting to understand it now.

When ever it comes do Diablo your content is the most exciting for me because I constantly learn new things or revalue old ones. Thank you for the time you spend for us mate!

I think the reason they called it Lucky Hit is because it is becoming an industry standard name that is being used more in games as a way to proc something other than critical damage. Sometimes an effect, sometimes just a separate damage multiplier, etc. The concept isn't new. We've called it procs for ever in MMOs, but other games using the same idea came up with different names, and Lucky Hit is the one that's been starting to stand out in some smaller games. Now that a game the size of Diablo is using the same terminology it is very likely to get properly standardized within the next several years.

Looking forward to your videos to watch while on my Diablo 4 journey. Always helpful for me on Diablo 3. Thank you for all your hard work sir.

Fun fact: Proc is a shortening of spec_proc, special process. Back in the EQ days we also said "Programmed Random Occurrence" to simplify what Proc meant for new players when they asked in chat. It's debatable if one is "more correct" as a definition than the other but they're essentially interchangeable in the gaming context

Goddamn, I come for the artwork. Raxx never disappoints.

Had to subscribe bc you really know how to explain mechanics the most efficiently, thank you.

The reason I'm not a huge fan of this is because there is a huge amount of effects in the game that are like Lucky Hit: 10%, which means on a skill that has a 20% lucky hit chance it's really only a 2% chance. Having a proc coefficient makes sense in games, but when the chances for something happening get that small it feels a bit silly. There are capstone passives that have like a 5% chance on lucky hit.

Very well explained, thank you

actually super helpful, great video on the topic ty!

Great explanation of the game mechanic. I think I heard you before going over this thing in a stream or a highlight video of D4 features, but still thanks for the video Raxx! Pleasure to see your content and cannot wait till you and every one of us can blast the game :) Question still remains: Is it worth paying attention to lucky hits? With the legendaries introduced so far, LH seems a bit lucklaster and I tried to avoid paying attention or building around it. Feels like those trinkets in WoW where you had 1 proc in 3 minutes and then a snake popped out of a dagger and did x damage.... kinda not how I like to build my character that slains 4546349 demons in those 3 minutes :D Anyone else feel the same way?

Great video, thanks again!

I liked the more detailed explanation. So Just to be certain I understand this mechanic correctly and If I do understand it correctly... then I think it's dumb of blizzard to display this information this way. Class: Barbarian Lucky Hit Bonus Chance: 5% Critical Strike Chance: 5% Skill (Hammer of the Ancients): Lucky Hit Chance 20% Legendary Helmet with Effect: "Lucky Hit* Damaging an Enemy with a Core skill has up to a 10% chance to extend the duration of Berserking by 1 second. Double that duration if it was a critical strike." So that would mean: You hit an enemy with HoTA -> the skill has a 20% chance to proc a lucky hit -> that chance is further increased by the character bonus of 5% -> meaning you have a 1 in 4 percent chance to proc a lucky hit effect. so 25% of the time, you have another chance of procing the Legendary Helmet effect 10% of the time -> meaning you have a (1/4) x (1/10) = 1/40 percent chance to proc the actual effect. So that means to get the critical effect, you have a 1 in 40 percent chance, times the characters critical strike chance of 1 in 20 to proc the "Critical Lucky Hit effect"...meaning (1/40) x (1/20) = 1/800 ? So why the heck doesn't Diablo 4 devs just put the calculated chance on the item and just simply say this: Legendary Helmet with Effect: "Lucky Hit* Damaging an Enemy with a Core skill has a 0.025% chance to extend the duration of Berserking by 1 second. Double that duration if it was a critical strike (0.00125%). Probably because it looks miserable to display it like that. I'm not great at math, but I think that's right

@Raxxanterax On Lorthrik build calculator the lucky hit chance is either per use or per hit i can understand how per hit works but i don't understand how lucky hit works for (per use) on ability's like the necro bone storm or decompose. Decompose is a channeling ability does that mean i can spam click decompose to spam lucky hit (per use) to proc like crazy? and does bonestorm only proc lucky hit once when i use it?

I like this explanation. It goes along with how i understood it working from experiencing it during the beta. I was kinda considering it a second layer crit chance of sorts, and it sounds like i was right.

It's worth noting that it's not even as good as that because you don't just have the skill percentage, but also the effect percent chance. So when kick was 100% that didn't mean you got your lucky hit every kick, it was 100% TIMES the effect's lucky hit. If the effect only said 20% chance to XXX then it would be 100% times 20% so 20% of the time it would proc. Now that kick is 40%, that 20% chance to XXX would only proc 8% of the time (40% times 20% = 8%). So lucky hits are much less commonly proccing than you'd intuit from the info cards. Even more confusing, and I don't know the answer to this, but when something increases your lucky hit chance, it's not entirely clear to me how that math works. Is that modifying the skill's chance? The Effect's chance? Their combined chances (after multiplying)? Would a different order even matter?

Really good explanation, thanks man!

Nice, thanks for explanation. I thought it's a chance for "higher tier" crit, like in warframe (crit chance above 100% allows for possibility to double whatever your crit damage modifier). Turns out vague naming creates more confusion. GJ Blizzard.

side question though, if you have something that give +10% lucky hit. does it change WW to 0.2, and HotA to 0.6 or does it change ww to 0.11 and HotA to 0.55 ?

Thank you for this! Very well explained

Another great video man thanks

This is extremely useful in explaining the mechanic in a way a non-math major can understand. Thank you!

pretty clear explanation, thanks for this!

Thanks for making this video so i will never have to explain this to my friends myself. You are the Boss!

Short and informative video i subbed

great explained RAXX, apriciate it ❤

Oh my god; thank you, this is the best explanation for the keyword I’ve come across! My only nitpick is that I son’t think ‘lucky hit’ is a nerf that’s spun to sound good. Like you said, it’s for balancing; but it gives developers another knob to both nerf and buff things

You should sell those MSPaint drawings as NFTs.

@4:03, its actually a way to BALANCE skills. You said yourself that some skills have low damage coefficient but higher lucky hit coefficient therefore giving them value aside from the things they already do. I know you said at the end its a balancing stat, I would just lead with that though because you have lots of people that hear the word "nerf" and have a mini heart attack. Great explanation, great videos Raxx.

We should have more streamers like this fella, that help other players with accurate information. Keep the good work

Hey Rax, question. What systems are in play when loot drops? Is it my lvl that dictates the item lvl/quality? What I am wearing? What items my character has seen drop in the past there by pushing the threshold? Do I need to be wearing it? Have it in the bank? Or just seen it drop is the past. Hard question to put into words, hope it made sense. Thanks!

great vid and easy to understand

Thanks for this video. Appreciate the explanation.

In PoE math this would translate in PoB to either gain 10% or in second case 50% as extra Lightning damage on average. In more real combat situations proc of a Lucky hit (now D4 mechanics and terms) has much more value the higher the single hit is, because thresholds for special effects like stun/shocks etc. are more easily met that way. So for fast low damage hits those Lucky hits won't have the same benefit as for slow hard hitting skills. In this example 0,1 vs 0,5 its even more emphasized.

Very helpful, thanks.

Thanks for the explanation. Didn't realise there was so much to theory building. This like Bachelor's Degree in gaming

What about the flat lucky hit % on your character sheet? Does that stack with the skill %, or is that just for basic attack?

Appreciate the black background to not burn out my eyes! 😁

Good general explanation but I would have loved to see some specific discussion about D4. Like how some of the lucky hit is generic and some of it is specific to a particular skill. How do those two things interact with each other? Also, what is generic lucky hit applying to if it doesn't state a particular skill?

So is it calculating per enemy? or per cast? For the Lucky hit? For example the flurry rogue do we get 4 rolls or just 1?

Nice, it's just a normalized proc coefficient. Finally someone explains it, great video.

You are getting better at Paint, and I didn't know it was even possible! The happy blonde barb deserves credit.

thank you for this, please explain what Fortify and Overpower is also.

@raxxanterax if hydra skill has 25% lucky hit, and the item says 12% chance on lucky hit to proc lightning lets say.. When you activate the lucky hit of hydras, you have a 12% chance to prox lightning? Am i understanding this correctly?

Once again raxx with the top notch paint skills. Respect 💯 keep it up bro 😂

Class is in session! Keep these coming.

Top tier explanation thanks!

Excellent information.

How do we find out what various coefficients on various skills are so that we can compare and decide what we feel will be most valuable while we're stuck in this week + theorycraft simulation?

Could you explain thorns mechanics on minions. What work and what not. For example does needleflare works?

What does "pierce" or "piercing" mean? Does it mean it can attack the next enemy in a line? O does it mean that it ignores barriers? O that it actually repeats the same attack on the same enemy? I need to know if it actually does something to a single target enemy, like Ashava for example

Thanks for the video. What Im struggling to find is how lucky hit chance boosters add to the base lucky hit chance. For example. Ice Shards has a base lucky hit chance of 16%. If I find an item that adds 10% lucky hit chance, Does my lucky hit chance go from 16% to 26% or does it go from 16% to 17.6%?

now all is clear. thanks mate.

what does lucky hit proc? My lucky hit aspects already have a proc % associated with them. What sort of things might use this? I'm playing rogue and I see I have skills or passives in the skill tree that do something on lucky hit, are those going to be the only things your lucky hit skills are proc'ing or are there others? also, even some of my passives have percentages already associated with them. Does that mean those lucky hit chances override my skill lucky hit %? I'm guessing those can be affected by lucky hit modifiers too.

Good info- thanks.

great content as always. hopefully youll get a solid few months from diablo 4 and build enough of an audience to move to new games comfortably

I'd take a video like that for overpower and all the other types of damage or crits linked to those.

are there any pesudo random mechanics implemented for these proc chance numbers in diablo 3 or 4?

You know youre a badass Diablo Content creator when David Harbour calls you out and says whats up on the Blizz NYC Dinner! That was Epic!

Thank you!!

the times i focused on this mechanic was when i was doing big aoe repeatedly and quickly with a huge lucky hit mod like execute non elite/boss mobs 6%+ chance

Do you have data mined for the Proc Coefficient for every skill in the game yet?

Lucky hit x Lucky hit chance = odds that thing will happen. So 8% lucky hit chance on my meteor enchantment, for example, multiplied by a lucky hit rate of say 50% on a move, means that 4% of the time my meteor will activate when hitting a mob with that move. Haven't tested it but it seems to check out thus far.

Are coefficient stats listed on legendary weapons? I don't recall ever seeing it.

So lucky hit doesnt have to do with the percentage on gear? I have gloves that says lucky hit has a 5% chance to restore up to 18% of your primary resource. I am using bone spear, so it would go off of the lucky hit of bone spear then 5% of the time it gets a lucky hit, it restores up to 18% essence?

Thanks for the video, this does help a lot. I am still wondering about some specifics, if anyone has any info I would very much appreciate any thoughts. I'm specifically interested in Necromancer Blight pools and their lucky hit chance. I know the Blight skill has a 40% lucky hit chance. I've seen people post in other threads that the 40% is over the duration of the DOT effect. Does that mean if I cast Blight, that out of the entire 6 seconds of damage over time, there is a 40% chance that it procs lucky hit once, like each pool of blight has a 40% chance to trigger a lucky hit? Or, does it mean that each tick has a 40% chance to proc lucky hit? What I'm hoping for is using lots of DOTs that are proccing lucky hit, that are triggering the 15% lucky hit chance of decrepify to cool down a skill by a second. I'm hoping lots of blight pools, will proc that enough to at least get a few seconds of cool down out of that skill. I'm not expecting a magic bullet, but am hoping to at least get a few seconds out of it, or am I way off? Has anyone tested?

another question - If i have 2 lucky hit "abilities", first with 10% chance and second with 20% and I used skill with 50% lucky it strike - how it works ? both of "abilities" can trigger in one time ? or it just can trigger max one of them, but not both ?

Does the Necro passive Hewed Flesh work with every instance of damage?

Thank you for explaining

Beautifly explained 👍

So basicly it's the percentage change that a proc will be triggered. Got it, thanks!

how does lucky hit works on AoE spells or DoT spells ? 1) If I cast blizzard and it hit 5 enemy - lucky hit is calculated for every enemy once (when I cast it) or individualy for every enemy? 2) when i cast some channel or dot spell - decompose - lucky hit chance is calculated for every tick ?

Lilith is going down for sure with this level of explanation. Thanks a lot!

So if i have the frost nova enchant (lucky hit: conjuration spell have 30% chance to unleash a frost nova) and i use ice blade with precision magic (71%*1.15=81% lucky hit) then each ice blade have 81%*30%= 24% chance to unleash a frost nova (freezing for 3secondes giving plenty of time to reproc a nova) + the node that make ennemies vulnerable with frost nova + the cdr node on ice blades(and as node) + ice shards enchant. Wouldn't that give me perma freezing inducing ice shard spamm?

My issue i find is the lucky hit on skills being in % and scaling it, its confusing from that pov. Also do some skills Snapshot lucky hit and some have lucky hit for each tick?

I hope we get a blue chest piece with a blue hood on it that makes our damage numbers into hand written paint ones

What happens when you have more lucky hit effects ? Let's say I have an item and it says: lucky hit 50% chance to do 50 lightning damage and I have another item or skills that says lucky hit 25% chance to stun mob. Let's say I'm using a skill that has a 25% lucky hit chance. When I get the lucky hit proc, do I have a chance on both effects ?

This is almost the information I’m looking for - but I think many people are asking this question because of the sorcerer skill tree specifically: We can reset a defensive cooldown every 10 seconds if our Critical is a lucky hit. And nearby we can raise critical hot chance OR raise lucky hit %, and we have no guidelines for which is going to be more valuable… Initial testing seems f’d in all directions, the skill almost never activates so we know there’s “other things”, and the lucky hit % certainly is one of them. So it’s not 5% critical • 5% lucky, it’s ALSO •.30 lucky hit coefficient on chain lightning etc… but I also wonder does for instance - chain lighting bounces not proc at all? Despite their increased crit chance from bouncing they never seem to proc much.

I used your firewall build to defeat Ashava. Thank you.

Ok now that the obvious stuff is out of the way can we have a discution about the relation between skill lucky hit, lucky of of the actual thing being proc'd and the extra lucky hit? How does it add up?

THANKS WE NEED MORE LIKE THIS

Surly if it does 100% lightning damage then you do 100% more damage in both scenarios regardless of the attack speed of the skill?

Thank you professor :D

Good explanation for D3, not for D4. You left key information out.

perfect, thank you

what about if you have 100% light damage on hit + 100% fire damage on hit, for example? will be both procced?

what a great way to explain the mechanic

Do you know if lucky hit with barrier chance and lucky hit stack additively?

Once again thx Raxx. But there is a Layer 2 to Lucky Hit. Your skill can have 40% Lucky Hit. But your legendary item have a 50% chance to proc on Lucky Hit. In that case, your legendary will only proc 20% on Lucky Hit.😅
