[3.10] THE SHARD STORM, Cold Snap / Ice Spear Occultist Build (Algor Mortis)

Cold Snap & Ice Spear

Update 6/11/20
Spoiler
Now that I've been pushing endgame content with this build, I've had to adjust and change a few things. Most of it revolves around boosting surviveability and removing unnecessary parts. To that end, I've removed the Herald of Ice/Curse on Hit setup, and replaced it with a Discipline gem. This means the build now has only one six-link and two four-link setups, so its easier to use one handed weapons/shields now. I've added the new PoB link and updated the rest of the guide to reflect the changes, and I've fleshed out the gear segment a bit more. There's also a new segment where I discuss beneficial enchants and cluster gem notables. I hope you enjoy!

Update for 3.11
Spoiler
So the good news is that we're mostly unscathed. Archmage support was nerfed at high gem levels, but not massively so that's fine. Fevered Mind was also nerfed, but I never used it in the build (even though I possibly should) so that's fine too. The good news is that Choir of the Storm was seriously buffed, as the internal cooldown for triggering it has gone from 0.5 to 0.2, which is quite relevent due to the rapid-fire and high crit nature of Ice Spear. Additionally some of the Notables added to the skill tree in 3.11 will be quite good, so overall the effectiveness of the build should actually improve a bunch. Going forward the biggest hurdle will be Algor Mortis becoming harder to get and most likely more expensive, but with it being an off meta unique it shouldn't be that expensive.

Right now the PoB is out of date, but once I'm able too I'll figure out the new tree and paste the link here. There shouldn't be too many changes, but now that Thunderous Salvos is on the tree rather than blight oil exclusive I will try to work that in, as well as testing out the new increased mana cost and spell damage nodes.





Introduction

Cold Snap has been a long time favorite skill of mine, and because of that I’ve tried to make it work in several leagues, but it never really got off the ground. I had all but given up on the idea, until 3.10 and came around and introduced two things that made me want to give it another try; a combination that solved Cold Snap’s charge generation/cooldown problem (Archmage Support + Forbidden Power), and a brand spanking new Unique that encouraged using chilling areas.

With the introduction of Archmage Support and its interaction with the Occultist’s passive skill Forbidden Power, generating Power Charges to use with Cold Snap’s Winter Bounty threshold gem is something that just happens automatically, so no more fishing for charges with the skill’s own passive! And when combined with Algor Mortis, the added lightning damage from the Archamage Support is increased by the chilling areas made by Cold Snap! So with this combo in tow, I set off to make a build all around it.

...And it didn’t work.

Sadly something was missing, and that was single target DPS. The build was working as intended, but killing bosses was an absolute chore. So I went back to the drawing board and dug up another long ignored cold skill, Ice Spear. I slapped the Archmage Support and an Unleash Support onto that, moved Cold Snap into a supporting roll, and I’ve been blasting and shattering everything in my path ever since.


How It Functions
Spoiler

With the Occultist Ascendancy passive Forbidden Power, we gain a power charge for every 200 mana spent. When socketed with the Winter’s Bounty threshold jewel, Cold Snap’s cooldown can be bypassed by spending a power charge. Therefore all we need to do is make Cold Snap cost 200 or more mana, which Archmage Support helps us accomplish.

Due to how this build evolved, we’re no longer using the support on Cold Snap directly, but the principle is the same. By casting Archmage supported Ice Spears, and the always expensive Arcane Cloak, we can maintain a steady supply of power charges to fuel Cold Snap with.

With Algor Mortis thrown into the mix, Cold snap should be used to create chilling ground under our enemies, before pelting them with a barrage of lightning charged Ice Spears for large chunks of damage.


Pros
Spoiler

+ Get to use unloved off-meta skills

+ Use a neat new Unique, Algor Mortis

+ High single target ranged DPS

+ Fast AoE trash clear with Cold Snap

+ Relatively safe due to Arcane cloak, a high freeze and chill chance, and the free Sap that comes from our chilling areas

+ Due to the Frigid Wake Occultist Ascendancy node, we're immune to chills and freezes

+ Normally chaos damage isn't a problem due to The Ivory Tower and all of our mana

+ It's quite intereactive, which is a plus for me after playing a lot of "one button builds"

+ With how the spells look, gameplay is quite clear and easy to see, unlike other builds which can become particle effect bonanzas and thus end up hiding important info


Cons
Spoiler

- Enemies getting close to you is real bad, gimps our DPS by quite a bit

- Ice Spear takes some getting used to, and because of the travel time you really need to lead your targets well if you want to hit most of the projectiles

- Can’t do Ele reflect maps (but then again what normal elemental build can?)

- Need to pay attention to mana, since it doubles as both damage and survivability

- Not the cheapest of builds, probably not a league starter

- Due to chaos damage being taken from our mana pool, if you’re not careful high spikes of damage will wipe out your mana pool and leave you vulnerable with no mana to cast skills.

- If mtx skill effects are the sort of things you need, there basically arn't any for this build, so you're stuck with the default appearances (Ice Spear and Cold Snap each only have a single one, and lets be honest they're kinda sub-par compared to effects other skills have)

Just the one video for now, I'm working on some more.

Skill Tree/PoB

Here’s the Path of Building link. I may update this and tweak it as I fiddle with it. Also be aware that the empty gem slot in the center is only empty on PoB and is actually holding

A Note on Historic Jewels
Spoiler


In terms of luxury items, Militant Faith is a nice historic jewel to have if you can find a good one. If you are looking to get one, "#### new faithful converted by High Templar Dominus" is the desired version because of Inner Conviction, but in all honesty the possible passives are the real reason to get it. For those who haven't used a Militant Faith jewel before, all the passives in a large radius around the jewel slot gain an added property of +5 or +10 Devotion, which then effects how much benefit you get off the Implicit modifiers on the jewel. There are a variety of possible modifiers, and while some are useless to us or downright detrimental, most all of them are wonderful bonuses. The ones to look for are Regenerate 0.6 Mana per Second per 10 Devotion, 4% increased Elemental Damage per 10 Devotion, +2% to all Elemental Resistances per 10 Devotion, 3% increased Effect of non-Damaging Ailments on Enemies per 10 Devotion, and 4% increased Area Damage per 10 Devotion.

(A side note on the other versions of this- As you can see I have the High Templar Avarius version, which grants the passive Power of Purpose; a skill that converts 80% of maximum mana to twice that much armor. The key word there is converts. When I got this I misunderstood how it would work, thinking it would just give a nice large passive bonus to our armor due to all of our mana stacking. But no, instead it straight up removes 80% of our mana to grant the armor bonus, so it's just detrimental to the build. Also with how lackluster armor is right now that is a poor trade off in general, but I digress..)


Gem links
Spoiler

Ice Spear - Archmage - Unleash - Lesser/Greater Multiple Projectiles - Increased Critical Damage - Awakened Chain

Our main bread and butter damage spell. Due to the unleash support and how mana hungry this is, it’s sometimes advantageous to have a bit of a breather between casts. In an ideal world we would put a Mana Leech gem on here, but doing so really hurts our setup. As silly as it since Ice Spear already pierces, the Pierce gem lets the first stage projectile pass through enemies if they're too close, which is insanely useful.


Cold Snap - Bonechill - Efficacy - Empower

With Algor Mortis as part of the build, Cold Snap should be mostly used to buff the damage of Ice Spear or to slow enemies down, but when clearing trash it's often faster to just spam Cold Snap. As a note, I'm not absolutely sure that Empower is the right choice for the fourth slot, but it's what I'm using for now.


Arcane Cloak - Second Wind - Frostblink

Because both of the active skills here are instant cast, neither get a second charge from the support gem, but the cooldown reduction is nice. Be advised when using Arcane Cloak to make sure you have as close to full mana as possible, and be ready to mana flask afterwards so you don't empty your mana pool completely.


Discipline - Blood Magic - Enlighten

This setup is used as a boost to our Energy Shield while not taking up any of our precious precious mana. With the Enlighten support gem attached to it at lvl 2, the gem neatly reserves 65% of our life, placing us at just the right percentage of life to count as "Low on Life" and benefit from the Pain Attunment keystone. And the best part is that since we're using The Ivory Tower, we actually overall gain survievability rather then just trading that reserved health for ES!


Ice Nova (lvl 11) - Cast When Damage Taken (lvl 6) - Elemental Proliferation - Vaal Ice Nova

This gem link setup is probably not necessary, but I’ve liked using it. Being a lower level, only the regular Ice Nova triggers off damage, which acts as a nice AoE freeze to stop enemies who are right on top of you. The Vaal Ice Nova is here just as an extra AoE clearing tool, and can rack up some mean damage numbers if fired off in a large cluster of enemies.


Clarity

This is here just because we’re massive mana hogs, so every last bit of regen is needed. The reservation amount is quite low tho, so there's no reason not to just use it as normal.


Stone Golem - Meat Shield

Another survivability measure. The regen granted by the golem is nice, and so is the AoE taunt.


Gear Choices
Spoiler

Part of the backbone of this build; Winter's Bounty is one of the key reasons that this works at all. The good news is that it's a cheap jewel to get!



Algor Mortis is important, as it both buffs our damage and reduces enemy damage output.



This is basically 100% mandatory. It's got a lot of regen, and when it's active spells don't cost mana, so it lets us spam Ice Spear and still regain our mana pool
(Edit: It's possible that while active Ice Spear looses the effectiveness of Archmage support, due to the spell costing zero mana. I haven't confirmed that yet though, so I'll update this when I know more.)
(Edit 2: So it seems that while active the damage bonus of Archmage is indeed lost, but that loss of damage is made up for by the ability to spam Ice Spear as fast as possible, so I still recommend it)




Extremely useful health and energy shield potion. Enough said.



Choir of the Storm is a nice DPS boost, due to Ice Spear gaining a ridonculous 600% increased Critical Strike Chance in the second form. It's not required, but it is highly recommended.



Now I'm not using this one, because I felt with my current gear I needed something in this slot to make me more survivable, but The Tempest's Binding is a perfectly fine choice for a helmet (if you don't mind being followed around by a ghost of the Blue Man Group). If you do end up using this, place the Cold Snap 4-link into it for the Ice Bite and Innervate bonuses.



The Ivory Tower is a useful choice because it let us use Discipline without reserving mana, but I suppose the build could function without it.



This isn't 100% necessary either, but the global +2 to Level of all Cold Spell Skill Gems is nice considering how many we use. It's also a cheap weapon compared to some of the other alternatives.



Speaking of alternatives, Shimmeron is a strong choice of weapon, especially now that I've altered the gem setup so that we don't need another 4-link. If you can offset the damage dealt by having Power Charges and constantly critting, this makes for a strong DPS boost and a nearly (if not over) 100% crit rate for Ice Spear in the second form.



Void Battery is another strong choice for DPS due to our usage of Power Charges, but the build can be strong enough on its own so it's not required if you can't get one.


If you've got the currency for it Call of the Brotherhood is a nice choice for a ring, but is quite pricey (hence why I don't own one to link right now)




And now for the Items that seem like they'd be good but aren't recommended with how the build works right now.


First up is Indigon. When I originally brewed up this build and started messing around with it I tried using it as an additional source of mana scaling that would compliment the Archmage support gem. While it could work in theory, in practice it leads to gigantic mana problems and a kind of feast or famine playstyle that ends up being dangerous if you can't cast spells when you really really need to Frostblink away.



Since we're all about Power Charges and mana, The Aylardex looks good at first glance. Gaining mana regen and a pseudo Mind Over Matter effect based on the number of Power Charges are both great things, but the reduced crit chance is just devastating to the build's damage, so this is a no go.



In a similar vein, Marylene's Fallacy is a nice amulet that has appealing bonuses, but once again the crit chance reduction is a real downside. However unlike The Aylardex, the loss of crit chance here is made up for in terms of DPS by the multiplier increase, and ends up being about neutral in terms of damage. However being net neutral isn't really a benefit, and so I'd recommend Choir of the Storm or a well crafted rare amulet instead.



Bandits, Enchants, and Clusters
Spoiler

Bandit Choice
Spoiler

I’d recommend Alira because it gives us everything that we want; mana regen and crit multiplier. The elemental resistances are a nice bonus as well. Choosing to kill them all for the two passive points is okay too, but it really doesn't give the same amount of value as Alira.


Enchantments
Spoiler

Labyrinth Enchants

For gloves the desired enchantment is Commandment of Spite, but any of the Spite enchants will do. The higher level ones deal more damage, but the real reason to get it is for the chilling ground, which is the same for all levels of the enchantment.

For the helmet, Ice Spear fires an additional Projectile is the largest bonus to DPS, followed by 300% increased Ice Spear Critical Strike Chance in second form. However, while it won’t show up as a boost on PoB and the like, Ice Spear travels 30% reduced distance before changing forms can actually be the largest DPS increase, due to the ability to hit enemies with the second stage at a closer range. Any of these three are fine, but i’d most likely recommend the distance enchantment because it’s a large quality of life change.


Blight Oils

As long as we're using Unleash, Thunderous Salvos is the enchantment of choice. Heck even if we weren't it would still be a tad appealing because of the 30% bonus to spell crit chance.

Other good (and cheaper) choices include Arcane Potency, Doom Cast, Crackling Speed, and Storm Weaver.

Super cool and interesting ! Thanks for sharing :-)
Any chance you got some video of the build in action ?
Not yet, but that is something I'm working on doing. I should have more free time in the next few weeks so hopefully then I can record and edit something. And thanks for checking this out! :)
Definitely need a vid to see the playstyle.

But nice build, always love a true selfcast witch.

Good news! I've edited and uploaded a short video of a map clear and boss fight to show how the build plays. Right now I'm working on a video of the final Redeemer fight, so that'll be uploaded soon. Let me know if I should be doing specific things in the videos to show off the build better.

Okay so just a short disclaimer/update note-

Some of the stuff in the build right now is sub-optimal, and I'm working on updating the guide. The main problem was my misunderstanding of Mind over Matter, and how it doesn't reduce damage taken to energy shield. Because of that I was greatly overestimating our survivability, and didn't allocate skill points so great. Long story short, I'm dropping MoM and the Curse on Hit support, and transitioning to a Low Life build by putting Clarity on the Blood Magic support gem as well. I will update the guide up top later today.

EDIT: Okay I've finally gone and updated the guide above. It's all up to date (for now)

Just a quick thoughts for 3.11 before I add it to the main guide:

It seems my first assumptions were wrong, this build isn't terrible as a league starter. The biggest hurdle is both Cold Snap and Ice Spear kinda sucking till later levels, as well as Archmage support not being available till level 31 (and even then it's not great at that low of a level). Just level with Freezing pulse or any cold spell of your choice and swap em out later. Certain BiS items are expensive as ever, but those aren't needed until super late so you can grind the currency with this build yourself instead of having to use a different toon to farm. (But seriously if you want an ideal Watchers Eye be ready to sell one of your kidneys to pay for it)

Overall the changes to the passive tree only helped us; and after some testing I think Dynamo is the amulet anoint of choice. It's a great passive, but located far enough from anything else we take that it's not worth the investment normally.

Also another thing I've come around to is considering The Ivory Tower as somewhat required. The build works without it, but lacking it makes you so fragile that it's not that viable above white tier maps.

Oh! One last thing is that as a weapon choice Tulfall works fine (sorta)! The inability to stay at max power charges is annoying, but generating them is so easy for us that it's not like there's ever a lack of them to spend on Cold Snap. So overall it's fine if you like that playstyle, but if you're doing that then Choir of the Storm probably isn't as good since you won't be constantly at a 90% or more crit chance.

The guide is very good, can you show the way through levels in the PoB?

LV 1 to 30 "Early Game" 40 pts skill

LV 31 to 60 "Mid Game" 40 pts skill

LV 61 to 99 "Late Game" 40 pts skill

... And the ascension tree

LV 1 2 pts skill
LV 2 2 pts skill
LV 3 2 pts skill
LV 4 2 pts skill


Note: Skill Points.
Sure! I'll make and post a section on leveling with the build soon. That should be easy to do since I've started the league with this build as one of my mains. Just a note untill I do; if you want to level with this the first thirty or so levels with most likely be with Freezing Pulse, since early on it's a much faster Cold skill to level with.
