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.

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.

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

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

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?

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

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

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

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.

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

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

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

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.

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

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?

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!

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 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.

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

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

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!

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.

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.

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

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

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

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.

finally someone explained it properly for dummies thank you

What's difficult to understand? Lucky Hit is essentially a critical hit that triggers a specific effect instead of just plain extra damage. Lucky Hit seems like a pretty trash mechanic 99% of the time, you'll have things that say 5% chance for an effect on lucky hit and you'll think, wow! That's pretty good. But then you realize your lucky hit chance is also 5%... so you have a 5% chance of a 5% chance... you'll basically never see that effect happen.

Very well explained, thank you

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 ?

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

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.

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.

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

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

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?

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

This explanation doesn't really clarify how lucky hit actually works in D4. There are two components: Your character's Lucky Hit value, based on the skill used and bonuses from gear/paragon/other buffs, capped at 100%, and then the Lucky Hit chance of the specific Lucky Hit proc on the applicable item affix/legendary power/skill modifier. The latter will say "up to an X% chance to do (proc effect)." This X% chance is scaled by your Lucky Hit value, giving your actual chance to activate the proc effect.

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

what i dont like about lucky hit is that a lot of pasives/legendary powers have a really low lucky hit %, and most skills don't go past 50% lucky hit multiplier which makes procs even more rare. I know you can get lucky hit as a gear stat, but at least in early game it doesnt feel very good.

Great video, thanks again!

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 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?

There should be a legendary achievement in game for getting lucky hit to proc something with frozen orb

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

I understand the purpose of Lucky Hit. I still don’t get how it’s used in d4 specifically, like how can we use it to our advantage. I assume different skills have different lucky hit %? do different weapons? I’d like to see actual examples in d4 to better understand it. thx for this tho as I was totally clueless before this video

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

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

Thanks for that Raxx. I actually didn't know what it was. Question I have now is... there are skills like lucky hit +5% - 10% - 15% for sorceror. Say your lucky hit was 0.1, would it be 0.1 x 1.05/1.10/1.15, or would lucky hit become 0.15/0.2/0.25?

Fabio The Barbarian is the artwork I didn't know I needed.

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

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 ?

Really good explanation, thanks man!

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.

First! I hope Blizzard gives us attack speed information for our skills in a future patch. Would be great to be able to calculate out attack speed vs damage when theory crafting builds. Great video explaining Lucky Hit Raxx, Love your content!

@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?

Class is in session! Keep these coming.

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

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

You forgot to mention the case where the attack and the Lucky Hit effect both have a non-100% coefficient. For example, most attacks and all effects. I don't think there's a single LH effect that doesn't have it's own coefficient. So, we get into the territory of stuff like Whirlwind (20%) and the Pressure Point passive (10% per rank) giving you a MASSIVE 2% chance to proc vulnerable on a target per tick of Whirlwind, up to 6% with 3 points invested in the passive. Lucky Hit seems like something you either want to entirely avoid, or go deep into and get as many LH effects as you can.

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.😅

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

The real question is: Is it Additive or Multiplicative? If I have an item that increases my Lucky Hit by 30% and the skill I’m using has a base of 0.1. Did I just get 0.4 or 0.13?

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

Hey Raxx, can you tell me If I understand this correctly please. Your lucky hit chance is calculated directly on your skill info... let's say ice shard starts at 16% and I have 50% extra lucky hit chance - Ice shard shows at 24%. From now let's say we take 3/3 Perma Frost (20% to get 15 mana back) so 20x .24 = Every shard has 4.8% chance to refund 20 mana. Same idea with 3/3 Snap Freeze ( Frost skills have UP TO 9% chance to freeze - not sure why they use the word UP TO here) so 9x .24 (iceshard) = Every shard has 2.2% chance to freeze. Last would be Elemental Attunement 3/3 ( Critical strikes have up to 15% chance to reset CD) so 15x.24x.35 (my cc) = Every shard has 1.26% chance to reset CD. Does that look good to you?

Thank you professor raxx for your lecture.

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

Short and informative video i subbed

Thank you for this tutorial for dummies

actually super helpful, great video on the topic ty!

p.r.o.c. stands for 'percent rate of change'. The 'proc' *is* the coefficient, not the action that occurs. These items are always 'proc'd' so you should say that they 'activated' not that they 'proc'd'. This is along the same ways most people misuse the term 'Elo' thinking that it's also a coefficient (but algorithmic) but in this case Elo is the guy's name who invented the system, E-l-o doesn't stand for anything =)

abusing proc chance is what made early wotlk rogues using 1.3 attack speed blue daggers as near BIS to abuse poison procs

Okay I'm a little confused. Does the "LP 100% lightning" damage mean when it procs a 70 damage skill now does 140 damage? If so wouldn't that mean in this scenario: Skill 1: does 70 damage with lucky hit 10 Skill 2: does 30 damage with lucky hit 50 So skill 2 does 60 damage every second hit and skill 1 is still doing 70 damage every 9/10 hits and 140 1/10 hits. So in that scenario skill 1 is still better? Am I misunderstanding something? Or is the math in the video just not thought out?

Explanation is good, but please, could you use at least excalidraw for better presentation🤓

4:20 as you said i look it as a way for developers have more tools to able to develop skill in better way and it not just balancing stuff it also create variation and build variants

The confusing part is that you actually seem to have multiple coefficients. For example, your core and basic skills have a lucky hit, but then execution has a lucky hit, and other passive skills have lucky hits like lightning for example. So if the lucky hit of my core skill is 20%, and the lucky hit of lightning is 20%, does that mean every 5 core skill I have a 1/5 chance to cast lightning? So basically every 25th core skill will proc lightning?

this really needed an 'explained' video. but the fact that this really needed an 'explained' video is telling. i preordered D4, and i'm not gonna ask for a refund or anything, but after these betas i just /know/ that i'm not the gamer they had in mind. i'm not sure who they did have in mind. or what's even in their mind...

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

Good explanation mate, I know I didn't need it, but it doesn't change the fact that this is a good service for the entire community. A doubt I have though with your example: Is Lucky Hit per cast or per potential hit? In the case of Whirlwind it's kinda obvious, the skill hits multiple separate times, but you could potentially HotA 10 different enemies at once. What happens then? 10 individual calculations on wether it procs, or does the game decide that as soon you click the buttom? One thing I wish though, is that they didn't have Chance on Chance with the current system. A lot of skills have "On Lucky Hit, % Chance to X". Seriously, do we really need that much down play on chancing? I have already rolled positive on Chance to Proc, just let me have the Proc afterwards.

So in order to be affected by lucky hit. In the skill tooltip MUST SAY Lucky Hit: does X effect right? I Ask because the sorcerer has a passive skill thar increases lucky hit but none of his skills says nothing about lucky hit doing something....only some legendaries if i remember correctly

ty lucky hit was confusing the heck outa me

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?

Another great video man thanks

what a great way to explain the mechanic

Bro, can't thank enough your reasoning.....thanks again.....

Thanks for this video. Appreciate the explanation.

Are you able to see the lucky hit of each skill easily? that's my big sticking point is how the hell will I be able to discern this based on which skill I use to attack? Love your channel btw!

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

Can you explain Fortify too? Like, Lucky Hit I understand is a thing that I don't understand, but Fortify MAKES me think I know what's going on, but when I try to look closer I totally don't get it.

During Server Slam, I managed to source a great party to take down Ashava after failing my first attempt. Each of us, all from different parts of the world, discussed our builds and referenced Raxx while opining on the game's mechanics... I can't possibly overstate how key your guides are to the Diablo community. Can't wait to see what you put out on release!

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%?

you did not answer the burning question, if a thing says: lucky hit you have up to a 20% chance to X, you use a skill with 20% lucky hit coefficient, and you have 20% lucky hit stat, what is the total proc chance? is it .2*.2*.2? .2+.2+.2? .2*.2*1.2?

It totally depends on what the 100% lightning damage is a percentage of. If it means weapon damage, a slower weapon would deal more damage and thus more lightning damage, negating the lower proc frequency. However, status procs such as "stun on hit" you'd always want as often as possible. So is the 100% lightning damage increased by the weapon's base damage? Or dps? This is unclear to me.

So, if an item says, "Lucky hit: 10% chance to stun." What this really means, if your Bash say has 50% lucky hit chance, that 50% of the time, you get a 10% chance to stun, essentially making it a 5% chance to stun. Is this correct? Therefore is a skill has a 10% Lucky Hit, then 10% of THOSE lucky hits will stun, essentially making it a 1% chance.

Lets say: What if you are a WW barb and Rage of Harogath dropped for you. WW has a 22% lucky hit chance. It says: "Lucky hit: Up to a 40% chance to reduce your cool down on your non ultimate skills by 1.5 seconds when inflict bleeding." You equip said armor. Now do you have 22% chance to reduce your cooldown when inflict bleeding ? Or do you have 22% x 40% = 8.8% chance to reduce your cooldown when inflict bleeding? What if you also have Gohr's Devastating Grips dropped for you. It adds 16.5% to lucky hit. So is it: 22%+16.5%=38.5% to proc Harogath? or is it: (22%+16%)x40%=15.4% to proc Harogath?
