Path of Exile: Cast On Critical Strike Guide

[@smithers4420]

I can tell how much my knowledge of this game has increased because I used to not understand a damn thing you said even when you were trying to explain relatively simple stuff. Now I totally get you, this video was very instructional and I think I'm ready to give this build a go!

[@resplendentobscurity]

As a total noob currently leveling a CoC character this makes the archetype much easier to understand - thanks!

[@voodoo1069]

A super common pitfall of CoC is having onslaught on kill (mainly from boots) which puts them over the attack speed they need which is like a 1/3 of your dps lose. Highly recommend if you don't have onslaught on hit or always active don't have it at all in your build or building around it will feel super lame on single target and often just ruin your damage on map clear.

[@ZeroIsMany]

I've had one build where I intentionally did that. My attack speed was setup for not having onslaught for most bossing, while trading the dps loss for movespeed was well worth it for maps. If I had to do a boss where it procs, I still switched boots.

[@OggyTheTiger]

if you dont have 52% cdr then yes it will tank your dps but with that cdr you can just balance the attack speed elswhere

[@pa2tea]

@@OggyTheTiger would you say 52CDR is a must??? Both my belt and boots and cdr but i wanted to get boots with tailwond etc. And idk if i can get both with my money would i lose alot of dps?

[@OggyTheTiger]

@@pa2tea CDR and attack speed is equally important as explained in the video, so yes you lose a lot of dps. You could try to get elevated cdr on boots and awaken orb with tailwind for relative cheap (4-5ex)

[@anthonyrichelle351]

Hey just wanted to put the calculus behind the tresholds here so anyone intrested can see : Servers ticks every 33ms. We will consider 3 specific ticks: 165ms (33 * 5) (Base Prock Rate) 132ms (33 * 4) 99ms (33 * 3) Base Cooldown is 150ms. The Formula for cooldown with CDR is the following : Cooldown = 150 / (1 + CDR) so for a specific server tick we have : CDR = (150 / Cooldown) - 1 Which gives us for : 132ms : CDR = 0.136 ~ 0.14 so 14% increased (POE always rounds against you) and 1/0.132 = 7.57 attacks / second 99ms : CDR = 0.515 ~ 0.52 so 52% increased and 1 / 0.099 = 10.1 attacks / second

[@ridd1ck]

man if i studied that much for university exam, i would be working in nasa now. This game made all of us professors. Thank you for info btw

[@kakefisk]

But what about ranged CoC, eh? How does say...barrage or tornado shot change things up?

[@Jimmy-nf9xh]

As someone who plays quite a lot of CoC builds, I would like to warn you all about Headhunter/Inspired learning. While wearing any (or both) of the items, you may (and will) steal a haste aura quite often. And since Haste aura gives you attack and cast speed buff, it can quite easily brick your build where out of nowhere, you will do literally 1/2 of your dmg

[@jackwabbit9784]

This is definitely the best job at explaining CoC anyone has ever done imo

[@psychederik]

you have shone the light. your insight has brightened the path for us all. your wisdom has cast a guiding light on our journey.

[@TheDontbeEvil]

Well done. A lot of guides I seen skim over the basics and go over advance techniques which led players to overlook critical gear resulting in unoptimized damage.

[@ArnoldMejia]

I remember doing my first CoC- the reddit write up was nice but this is immensely a better resource. Thanks for making it.

[@Daethbane]

I went away from your CoC FR build and immediately regretted that, moment of temporary insanity. You are by far the most helpful PoE streamer and your Discord is amazing. I'm now having so much fun with my build and bragging about my currency gains in your channel! You rock man!

[@Afgust_0]

I wish I saw this video earlier... Incredibly well explained on all of the intricacies of CoC builds, one thing I would add is the +3 mastery and level 6 of the gem helps A TON to hit the CDR breakpoint along with 20% CDR boots

[@WebCamCartmell]

this is great info, breakpoints were confusing for me for a while, thanks for laying them out in an easy to understand way. i'll be playing coc next league

[@prototype7696]

I've been using Storm Rain for my CoC and it's been a ton of fun! I might use something like tornado shot barrage for clear, but I'm not sure yet since I'm still in act 7 atm I'm casting Discharge with astral projector and endless misery with a power charge stacking assassin and the damage has been good so far. I might also experiment with anomalous storm call to take advantage of the increased AoE with no downside

[@MeowTime24]

If you are at the 14% 7,57 breakpoint, do you benefit from having higher cdr, but still under 52%? or it doesen’t really matter if you have 15 or 45%?

[@RobertOkadar]

Nice video! It would be also helpful for new players to explain how critical strike chance is scaled (for spells, attacks, minions, heralds, global...). But can also be a separate topic and a new video.

[@tarotaro6933]

[@kedalin]

You sure that he didn't make it already? Did you check his videos under the profile?

[@epictrueness]

So I have 37% CDR from awakened CoC and 15% from my boots. Ingame it says my triggering spell has 52% cdr and cyclone 15%. In PoB my damage decreases if I go over the first breakpoint with attack speed. What am I doing wrong? Does the gem not work for cyclone any more?

[@PhunnyConflicts]

cool video. i've been trying to find videos that break down builds like these. would like more in-depth guides like this if possible.

[@Kyramesh_]

so, what's the rule on atk/s. do you aim to be just over/under/right at the calculated optimum?

[@bikesnblades6737]

Ideally you're always as close as possible to the threshold, but don't go over it. I believe hitting the exact threshold number is fine, but am not 100% on that.

[@burkles4456]

[@magnorafaeltrevisan9930]

Hello @subtractem, first thx for the video. Then, im getting energy shield problems with you new COC vortex assassins build. My energy shield is gonne really really fast, and im staying without mana to proc vortex and frostbolts, im with 55 cdr and 10.0 spec, any ideia what im doing wrong??

[@dervakommtvonhinten517]

question, wouldnt it make more sense to ignore cdr and just go for lots of attacks and more damage/crit instead of cdr? with enough attacks, the odds are very good you can prog it about every server frame anyway no?

[@TheLawrencesoh89]

hi i love your learning video and especially the how to build a COC breakdown video. do you think if you can make a how to make a poison build breakdown?

check out the rest of the playlist on the front page, i have some explanations of poison and damage over time

[@TheLawrencesoh89]

​@@subtractem ​hi thanks for replying, i have view it for couple of time already before this video🤣 my question here is 1. among the so many stats. can you give us a guideline on which stats is actually more important or all are as important. like faster poison (you said something like "100% faster poison" in that video) seem be the most important stats. i believe it to be call "deal damage faster". and also like i should get skill that can hit mobs as much as possible per second to get alot of stacks 2. temporal chain, i believe less action speed is the stats that sort of increases the increase the "faster poison"? i am a guy who play POE 4-6 hour a week. but i would love to personalize my own build and would like to play something like split arrow poison, although i think it is unrealistic.🤣

[@CHillmAST3rP]

This is a great explanation, thank you very much

[@sorasan1875]

super noob enquiry : so .. if I want another set of CoC on a 2 handed weapon, that needs to have a seperate attack skill to trigger the coc right ? its not similiar to spell trigger as in just 1 atk skill can trigger all the coc at different items ?

[@psychederik]

if i have 52%+ CDR can i go slightly above 10.10 attack speed? something like 10.25 or will that negatively impact my build

[@testudoo]

When to switch from the Essence Drain leveling build to CoC Cyclone + Forbidden rite? What are the status/triggers I need to pay attention before doing moving on to?

[@G33KST4R]

Is this the same for bow skills? I'm trying to do FR CoC but with Tornado Shot. I don't know how to calculate the trigger rate on PoB

[@OldGregggg]

Nice explanation for new players, great work :) One critique, at 16:00 I believe you're mistaken about onslaught not being calculated (unless I'm mistaken). I'm playing CoC Ice Spear and have manually checked my aps in a map using the char sheet, I looked to see if there's a difference once I get onslaught and I noticed there was. (lined up perfectly with PoB) Alternatively I believe you can use the Silver flask I think? The flask that gives onslaught. Pop that in your hideout and you can see it there as well. However if you're talking about generally understanding your aps without having to have your char sheet open while playing then I get it :D

[@BuzzaB77]

aaahahhh. it clicked. we have this in rocket league too, where the physics engine is fixed at 120 ticks PS but the game engine at large accepts inputs at frame rate, so its possible to miss if you're not at a multiple of the phys engine. So POE's engine is 60fps internally?

[@Dreschau]

Good guide to cover the basics.

[@LivermoreJr]

Sorry a damn question from newbie, why the left side of pob template has a green wording: CoC Triggering Skill:Cyclone? Mine pob seems missed out something. Btw I'm playing ice nova cyclone assassin.

[@LivermoreJr]

@@subtractem Thank you

[@travissullivan6575]

This makes me want to try out a coc-slinger build

[@garetwebster5002]

@subtractem I don't think the attack speed works quite how you described in the video with cooldown based builds. I think path of exile has some sort of smoothing where if you do two attacks in the same server tick they get processed across multiple server ticks. It's still really important to reach at least 10.1 attacks per second, but it doesn't hurt you to go over. I believe this because I did pretty extensive testing on seeing if raising my attackspeed past the 10.10 attack speed breakpoint would signifigantly impact my damage. I would test by fighting dunes hillock in a white map with reduced damage and seeing how long it would take me to kill it. I also used frostbolt as a my cast on crit spell because it's extremely easy to see when it skips a cast since it stays onscreen for many seconds. Changing my attack speed didn't cause more spells to not be cast.

[@subtractem]

This is incorrect. Your DPS will go to exactly half if you go to 10.2, you absolutely will cast fewer spells. It's one of the most tested things in poe.

[@garetwebster5002]

@@subtractem do you have anyone who actually tested this? Because I rigorously tested it myself and was not able to drop my dps by even 10%, much less 50%.

[@subtractem]

I've demonstrated this myself multiple times on stream. It's very easy to test. Do a no-CDR setup so the default trigger rate will be 6.06 times per second. Raise your attack speed to 6.1 and you'll see roughly 3 spells a second instead of 6. It'll be very obvious. It's also easier if you do something like use Southbound gloves so you can just test on a single mob without having to reset. My suspicion is that you likely don't have the correct accuracy, crit chance, or attack speed in game so your test is flawed. If you're basing it on the in-game tooltip, for example, that will often be incorrect because it doesn't report based on temporary buffs or debuffs on enemies.

[@twelvesevven4678]

Do the crit's from hits work or just attacks, because Spark hits but is a spell, right?

[@Stonewall337]

[@franciscosaltojusto7662]

Quick question, the build breaks if you have too much ASPD for the CDR breakpoint, but does it go the other way around?

[@subtractem]

what does "the other way around" mean? less aspd than your breakpoint is fine.

[@SynteriActual]

I'm a little late here but wanted to ask if the server tick is the same on console if you know?

[@mrmozao]

now I know why my CoC Cyclone VoP isn't working as expected. ty sir!

[@АлексейБычков-х7х]

awakened coc has 0.15 self cdr and i can reduce it from belt and jewel (sum 15% = 0.13 cdr) , but this gem can give 37% reduce cdr only for supported gems. how is awakened cock can get 52% reduce cdr if 37% he gives to supported gems? forbiden rite has 0.10 cdr, but where my awakened coc has more cdr than 0.13 (15% reduce from belt and jewel)?

[@dirrtycobra]

So, what’re you’re saying is.. If I have 14% CDRR and my attack speed is 7.56, the next possible DPS increase will be at 52% CDRR with 7.58 attack speed? I’ll just stay away from 7.57 but it would work from 14% to 100% I’m assuming. Now I’m wondering if I had 15.14 AS w/ 14% CDRR I’d have the same dps as 7.57 AS w/ 14% CDRR. If this is all true then I understand everything. :)

[@jonnyjazzz]

I am just starting the vid, but I'm curious as to how you deal with CoC mana costs without Mageblood and mana cost mana flask. CoC's dark ages started when they made CoC cost mana, and it's not really been the same since.

[@subtractem]

Tons of tools to deal with it: Replica conqueror's efficiency (-9 mana cost), Ring -7 mana cost * 2 (-16 total with catalysts), mana cost craft on flask (25% reduced cost), Gemini Claw (14 mana gained on hit), Essence Sap or other sources of mana leech. With all of that in my build my FR goes from 52 mana cost to 15 and I'm gaining 14 mana per enemy hit from the claw. I'm actually way overkill at the moment but it means I can even ignore map mods that make mana annoying. It requires a little problem solving but it's really not too difficult. The rumors of CoC's death in 3.15 are greatly exaggerated.

[@quentinmt5341]

I did a CoC build a few leagues ago without paying much attention to these numbers. Gonna check it out how much damage I most certainly lost

[@CapnCrunchESO]

My attack speed is 14 and my trigger rate is 7. Does this mean I need to somehow find 52% CDR? I added like 13% CDR on my boots in POB and my DPS only went up 1,000

[@subtractem]

You need 52% CDR to be over 7 aspd and less than 10.1, you can _never_ go above 10.1, you need to lower your attack speed.

[@CapnCrunchESO]

@@subtractem sorry last question, when you said if youre unable to get the required CDR you can run 2 skill gems. Can you run 2 of the same skill gems or do they need to be different skills?

[@subtractem]

You could double the skill gems and then go over yeah, this will cut the DPS of the primary gem in more than half though since you lose another support gem (and you already lose 2 because of attack + cast on crit). This is generally not worth it.

[@Piezzu]

hey Sub, i have an unused mageblood i was wondering how the pob would change if i slapped that in

[@subtractem]

Check out the CoC FR builds on poe.ninja, it's the natural progression from where my build is at the moment...just a big monetary jump.

[@thoriandragontamer1411]

Is there a similar setup for cast while channeling? Like, did cdr affect it, and has someone figured out the breakpoints for that?

[@subtractem]

CWC is much simpler. You don't care about anything that I really listed here except the damage the spell itself does. The main difference is you don't have to hit to trigger anything, it's just automatic. The downside is that it caps at about 3 triggers per second and you can't modify it so the damage ceiling is generally much lower.

[@NatPage]

[@mohdehsan3775]

This build can it sustain 100% deli and simul without mageblood?

[@bossl6982]

I was playing CoC icespear/eye of winter with lancing steel last league. Probably the most fun build i've played because of how complex it is. Still don't fully understand if breakpoints apply to skills like lancing steel though since they have a fixed interval of projectiles that hit the enemy. All I know is that it killed anything and my GPU at the same time.

[@robotrock909]

Thanks to this vid I finally truly understand the breakpoints. If I'm at 9.91 trigger rate, is it worth going for 10.1 or is it close enough to not be worth the effort?

[@subtractem]

You'll get about 9% more damage. Always worth to go as close as possible. Aspd scales linearly and is usually super easy to get.

[@robotrock909]

@@subtractem I got it right at 10.1 but then re rolled the elevated tailwind value on my boots and I think that messed it up again, that or gem levels. I actually built way too much attack speed and am having to trim it back to hit the breakpoint lol.

[@aryk_st4789]

Edit: it was fixed! Hey, You mention checking tailwind, which doesn't seem to be correct. What action speed and tailwind does is speeding up "animations" of the character. The same thing as chill or temporal chains do with negative effect. Normally increasing the speed of the animation increases its attack speed if the skill does full cycle animation every hit. Cyclone though is a channelling skill and it starts with start animation and after that you're just spinning and just seem to "produce" hits with 300% AS. So action speed doesn't increase trigger rate for CoC, while PoB incorrectly includes it in trigger rate calculations. Action speed increases wind up animation of Cyclone though

[@subtractem]

That is correct for cyclone but other attacks will be affected, just covering all my bases. Good clarification though!

[@spiritkid9109]

If I remember correctly this was a bug that got patched and Tailwind does now affect Cyclone. Needs testing, I can't find the source for that but I remember hearing that.
