⦁ So I wanted to play Sparks, cuz this is so much fun to watch how it covers entirely screen and just destroying everything in around and even further out of the screen. Although Self-cast version was just too annoying for me, especially Spell Echo Support with freeze our char to finish animations. Also important point for me was that Build have to be cheap for playing easily every league
⦁ Build idea started on 3.29 with thoughts - OK, if Spark Traps, Spark Mines, Spark Totem, Spark Brand and Spark CwC worked so let's try Spark but CoC version this time. This way I started playing Spark + Cyclone + Cast on Crit aka Spark CoC and I loved it too ⦁ Spark of the Nova gem is awesome and that Build is nice hybrid for Cyclone Cast on Crit and Spark fans, easy to playing and something not typical. You just get into enemies and melt them. I was very suprising you can destroy T16 maps even on low budget cost. I'm very proud and happy I invent that and can share with you guys. I hope you will be enjoy like me :) 
Spoiler
⦁ It's very simply to playing - just spin with Cyclone and hit enemies, which cast 2x Spark Nova thanks to Cast on Crit and Mjölner
⦁ Main point of this setup is Perfect Crime from Saboteur Ascendancy - Triggerbots cause each trigger of Spark Nova is doubled, which has amazing potential ⦁ Build is based on Life and also has multiple layers for defense so it gonna tanky. This setup utilizes Eldritch Battery + Energy Shield as source to spam skills

1) FINAL (92 lvl) - both are the same, just from other source:
⦁ 6L CoC - https://pobb.in/fFzSmdQfzonW |||| 3L Mjolner - https://pobb.in/PSUuxloC7YL7 2) ELDRITCH BATTERY (24 lvl) - https://pobb.in/Ifs01V90i_dt 3) SPARK OF THE NOVA CWC VERSION (around 70 lvl / after campaign) - https://pobb.in/rsqx01mjr5z8 
Spoiler
You need 100% Hit Chance + 100% Crit Chance on Cyclone:
 
Spoiler
Spoiler
⦁ You like Cyclone and Cast on Crit?
⦁ You love Spark? ⦁ You hate self-cast with Spell Echo Support? Then it's Build exactly for you my friend! Also why Spark CoC comparing to for example CoC Ice Nova of Frostbolts? Well, it's hit just one on area and that's all. Although Sparks mechanic is perfect for that style - we are just spinning through map, but behind us Sparks still bounce from walls / objects and destroying everything. It's super funny and have amazing potential for clearing. 
Spoiler
1) LEVEL - unfortunately you need high lvl - even 90+ to start effective playing. So before that I recommend playing Spark CwC version (check my other Guide).
2) UNIQUES - To open full potential and comfortably playing you need Watcher's Eye Jewel with mod on gain ES per hit while affected by Discipline. Also Astramentis is needed for high stats requirement. For start after campaign (CwC version) you need just Mjölner + Lycosidae + The Devouring Diadem + Astramentis, but they are even cheap. Also Belly of the Beast + Replica Stampede and Ancestral Vision Jewel are nice upgrade for later. 3) STATS - you need 100% Hit Chance + 100% Crit Chance atleast for single target (rare, Bosses). Hit Chance it's easy obtained with just using Lycosidae Shield. For Crit is more harder, cuz you need a multiple source for stacking that. 
Spoiler
The main things we are based on this Build:
1) Spark Tags ⦁ Duration / Lightning / Spell / Projectile / Critical 2) Offensive Scaling ⦁ Spell Damage / Elemental Damage / Lightning Damage / Projectile Damage / Projectile Speed 3) Defensive Scaling ⦁ Life / Regen Life / Elemental resistances / Chaos resistance / Evasion Rating / Suppression Spell Damage 4) Utility Scaling ⦁ Cooldown Recovery Rate / Cast Speed 
Spoiler
How Build is feeling in just playing
1) CLEAR - destroy everything very fast 2) SINGLE TARGET - is so good, but it can lack that sometimes 3) DEFENSE - even tanky, can take a lot 4) OVERALL FEELING - nice to play, playing as Spinning is main point, you can cover whole screen in Sparks in good time. A bit annoying is that if you wanna throw Trap to activate node for Life regen, you must stop a moment or push this button longer. Also Boss of map can take a bit long time, especially if you don't have Flask Charges for full 100% Crit 
Spoiler
➕ Funny - Tons of Sparks
➕ Spin To Win :D ➕ Cheap ➕ Easy leveling ➕ We can have 2 Anoints ➕ Amazing clearing maps ➕ Good single target Damage ➕ Decent Life pool ➕ Tanky and very good sustain ➕ High defense against elemental Damage (with Taste of Hate) ➕ Good regen Life ➕ Immunity for Blind, Ignite and Shock ➕ Nice Delve runner ➕ Generally on budget gear we can start doing red maps ➖ Can be a bit squishy before you get more Life ➖ High attributes reqirement for Mjölner (412 Str + 300 Int) ➖ Need stacking Crit Chance ➖ Mana management before get Jewel for easy sustain of that 
Spoiler
You have prepare for cost 250-300+ Chaos
The most expensive will be: ⦁ Watcher's eye Jewel for sustain mana ⦁ Belly of The Beast 
Spoiler
Just number of some stats what Builds can do, some kind of goals we gonna to achieve, of course some of them can be more or lower but it's good state. Numbers are based on full buffs, Auras, Flasks etc. while we are on active playing
⦁ AVERAGE DAMAGE ON SPARKS TOOLTIP = 17k (6L) & 14k (3L) ⦁ LIFE POOL = 4k+ ⦁ SPELL DAMAGE SUPPRESSION CHANCE = 100% ⦁ EVASION RATING = 20k+ ⦁ REGEN LIFE PER SEC. = 1000+ 
Spoiler
Build has these defensive layers
1) LIFE + REGENERATION - with decent Life pool + amazing regen via Ascendancy you can recovery high amount in short time 2) SSCALING EVASION RATING - with high chance to evade attacks you can feel very safe going through the map 3) STEELSKIN - free Shield with 2k+ will help against hard fights 4) SUPPRESS SPELL DAMAGE - is great mechanic, which decrease significant Damage from spells, we get 43% less Damage from that 5) HEARTSTOPPER - big 50% less hit Damage / 50% less dot Damage (one of them every 5 sec.) from Ascendancy is huge 6) ANCESTRAL VISION JEWEL - it gives even over 45% chance to avoid elemental ailments via Chance to Suppress Spell Damage 7) IMMUNE - you don't care about Ignite, Shock & Blind effects 
Spoiler
Spoiler
Spark of the Nova gems, which we are using in Build is transfigured gem of standard Spark, but has more damage and more projectiles. While we using it as Cyclone + CoC and with Mjölner on hit, we don't care about Cast Time. So here are 3 important things you need for Spark works properly
1) MORE DURATION = 3.19 seconds - 3 passives in tree + Duration Mastery  2) PROJECTILES PIERCE ADDITIONAL TARGETS = 3 Pierces - just 2 passives in tree  3) PROJECTILE SPEED = around 120% - here we need Faster Projectiles Support on Damage setup + Projectile Mastery + Ballistic node from tree   
Spoiler
Core item of this Build and it's cheap. How it works?
⦁ It allows use 4x Auras ⦁ Every 5 sec. regen a high amount Life and ES for every corpse from Feast of Flesh ⦁ It gives Eldritch Battery Keystone, so we have free 1 passive point 
Spoiler
While we playing with using Mjölner we need 412 Str + 300 Int and we have multiple source for stacking that
412 Str you get from: ⦁ Passive Tree (especially nodes with +30) ⦁ Astramentis Amulet ⦁ Rare Items (Rings, Belt) ⦁ Utmost Might Anoint ⦁ Jewels 300 Int you get from: ⦁ Passive Tree (especially Utmost Intellect with +40 & increased 8%) ⦁ Astramentis Amulet ⦁ Jewels 
Spoiler
It's a Crit Build, so you have to get 100% Crit on Cyclone atleast for single target (rare, Bosses) to maximizing effectiveness. We have 2 sources of that: flat Crit and increased Crit.
First how much you gonna need % increased source is depends on quality value on Mark on Hit Support, of course these numbers are at 20 lvl gem: ⦁ (0% quality) = 8.68 flat = you need 1053% increased ⦁ (4% quality) = 8.70 flat = you need 1050% increased ⦁ (20% quality) = 8.76 flat = you need 1042% increased Flat Crit you get on: ⦁ 5% from Mjölner ⦁ 2% from Critical Strike Support ⦁ 1.18%+ from Assassin's Mark via Mark on Hit Support ⦁ 0.5% from Pure Talent Jewel Increased Crit you get on: ⦁ 290% from 5x Power Charge (each of 58%) ⦁ 255% from Passive Tree ⦁ 137% from Critical Strike Support (20 lvl + 20% quality) ⦁ 100% from High Voltage node ⦁ 100% from Diamond Flask ⦁ 60% from Pain Forger Anoint ⦁ up to 55% from Flask mod "Increased Crit Chance during effect" ⦁ 20% from Cast on Crit Support (20% quality) ⦁ 20%+ from Diamond Ring ⦁ 10%+ from Rare Jewel ⦁ 10% from bonus Quality on Support gems for right color (Critical Strike, Cast on Crit) 
Spoiler
On this setup we don't stack too much Attack Speed, cuz we have a lot other more important things to take. Although while Attack Speed for CoC is always more Damage, you have to be carefully with Mjölner trigger, cuz you can decreasing Damage output for that. In this setup we have up to 44% Attack Speed, but if you would have other sources just don't go over 47% Attack Speed for Cyclone
So we have Attack Speed on: ⦁ 22% from Blood Rage (20 lvl gem + 5% quality + 2% bonus quality) ⦁ 12% from Frenzy Charges (each of 4%) ⦁ 10% from node in Passive Tree 
Spoiler
 We are playing Double Spark - one 6L Cast on Crit, second 3L Mjölner weapon. Also after that further they are repeat twice with Perfect Crime. So you trigger Sparks from gem, then Triggerbots causing it trigger twice yet, the same with trigger Sparks form Mjölner, Triggerbots trigger twice aswell. It's so strong option, which allows you get a huge amount of Sparks and Damage output Although you need to know that triggers from these 2 things are a bit different: ⦁ CoC gem is always trigger Sparks every 0.15 seconds at 20 lvl, but you decreasing it with Like Clockwork to just 0.10 seconds and Attack Speed matters, cuz it increasing Effective Trigger Rate. However you have to hit enemy with Cyclone and it must be Crit ⦁ For Mjölner Cooldown Time is 0.25 seconds, but you can also decreasing it with Cooldown Recovery Rate - so with Like Clockwork you get 0.17 seconds and also here Attack Speed matters, cuz it increasing Effective Trigger Rate. However you have to hit enemy with Cyclone, but it doesn't must be Crit and then you cast Sparks 
Spoiler
This mechanic is very strong, cuz it has cap of 100% Chance and get 40% less Damage taken from Spells. That's why in final setup you should aim for constant 100% Chance without conditions like: Flask or while on Full Life / ES. Unfortunately for this setup constant 100% is hard to get, we can get only over 95% of that and rest you have rely on something else. Also you have to pick Spell Suppression Mastery with "Chance to Suppress Spell Damage is Lucky", but downside is you never get 100% Chance with that
--> Here you have explanation about "Calculation of Lucky" from reddit: reddit.com/r/pathofexile/comments/128tdo6/simple_graph_for_the_value_of_chance_to_suppress/ Chance for Suppress Spell Damage you get on: ⦁ 57% from Passive Tree ⦁ 21%+ from Magebane Keystone (each of 1% per 15 Dex) ⦁ Spell Suppression Mastery "Chance to Suppress Spell Damage is Lucky" Standard is 40% less Damage taken, but you can push it to 43%. You get it on: ⦁ 3% from node in Passive Tree 
Spoiler
We need enough Mana pool just for 4x Auras, while we using Energy Shield as source for spamming every skills
For Mana pool you need put all Auras into Unique Helmet + stack a bit Mana Reservation Efficiency of Skills: ⦁ 24% from Passive Tree - 2x nodes: 8%, 16% ⦁ 12% from Mana Mastery ⦁ Rest of 10% from Rare Jewel (2%) + 8% from Passive Tree (2 points) For sustain Energy Shield you need just Watcher's Eye with mod: * you gain 20-30 ES per enemy hit while affected by Discipline So before you get this Jewel your potential is limit and you need relies on: ⦁ Fest of Flesh from Helmet ⦁ Inspiration Support on CoC setup ⦁ Rings with non-channeling skills have -mana cost ⦁ Vaal Clarity 
Spoiler
⦁ Help Alira for 15% all Elemental Resistances, cuz get high Resistances can be hard
Spoiler
 
Spoiler
STEP 1---SWAP ON SPARK NOVA CWC VERSION---
We swap here after campaign when you entering on maps. Do these: ⦁ Respec Saboteur nodes into Perfect Crime + Like Clockwork ⦁ Respec Eldritch Battery Keystone (cuz we have that from Helmet), so we have free passive point ⦁ Take things for More Duration + Projectile Speed + Projectiles pierce additional targets (check Spark of the Nova section) ⦁ Get a bit regen Life on eq ⦁ Go activated all 3 main Auras: Wrath, Grace and Discpline. Try fast get 4th Aura: Summon Skitterbots ⦁ Take right Gems and Links from final setup. Also for start you need Vaal Clarity instead of any gem You respec some points (red lines in photo) and pick others (green lines in photo), in aggregate you respec 36 points:   STEP 2---FOLLOW FINAL TREE CWC VERSION--- After swap on Spark Nova you just follow final tree from Passive Tree section from this guide: https://www.pathofexile.com/forum/view-thread/3997149 Pick next nodes, but my suggest ways in order will be: 1 - get Life nodes 2 - maximazing Damage 3 - go for Cluster Jewel Socket (it's nice for increasing Damage)  STEP 3---RESPEC CWC INTO COC--- After step 2 and if you wll be ready, just change CwC version into CoC - just check final tree from Passive Tree section You respec points (red lines in photo) and pick others (green lines in photo), also totally remove Cluster Jewel. In aggregate you respec 26 points:

92 LVL
 
Spoiler
1) Basic of sustain source to spam skills. Also you have already free allocated it from Helmet.
 2) More Damage so it's always very nice.  3) For to reach high value of Chance to Suppress Spell Damage.  
Spoiler
1) Super boost to Damage, cuz we have high amount of Attributes.
 2) Very helpful on maps when you enter there and for white / blue moobs.  3) Duration is very important for this Build.  4) Projectile Speed is also needed for this setup.  5) It's very helpful to increasing Suppress Spell Damage chance, although it doesn't show on character sheet and also it doesn't count for Unique Jewel Ancestral Vision with it's synergy.  6) We need this for get more Auras.  
Spoiler
Spoiler
We are playing 5 Uniques
1) WATCHER'S EYE - Just this 1 item with good mod completely resolve sustain source. 2) PURE TALENT - With flat Crit, it's so nice for maximizing Crit Chance. 3) ANCESTRAL VISION - It's big and scale with our Chance to Suppress Spell Damage, so another great defensive layer. 4 & 5) FORBIDDEN FLAME + FORBIDDEN FLESH - With these 2 you get for free Heartstopper node from Trickster Ascendancy. So it's a big defense layer. 
Spoiler
We are playing just 1 Rare
Rare - You need just min. 2% of Mana Reservation Efficiency of Skills, then rest look for Crit Chance and resistances 
Spoiler
Spoiler
Str - 412 FOR Mjölner
Int - 300 FOR Mjölner Dex - 155 FOR Vaal Grace 20 lvl 
Spoiler
We are playing 6 Uniques
1) WEAPON - second Spark, it's nice boost for Damage and amount of Sparks. 2) SHIELD - totally resolve problem with Accuracy Rating, your hit chance is always 100%. 3) BODY ARMOUR - we just play rare item, but this Unique is huge for improve Life pool. 4) HELMET - socketed gems have less mana reservation, so we can put extra one Aura. Also Feast of Flesh is nice for regen and sustain. 5) BOOTS - always base 150% of Movement Speed, you don't care about Cyclone penalty and you have free flask slot. Also you can add 2nd anoint. 6) AMULET - the best choice for stacking Str and Int, which are so needed. 
Spoiler
* For Body Armour + Helmet + Boots you need use just Rare with Life, Resistances, Evasion + Energy Shield until you upgrade for Uniques
1) GLOVES - with Evasion 2) BELT - with Life + Resistances + Attributes 3) RINGS - with Life + Resistances + Regen Life + Attributes 
Spoiler
You need on 1 from 3 Flasks this mod (here I recommend get it on Sulphur or Jade type, cuz on Diamond is too expensive)
⦁ % increased Critical Strike Chance during effect 1) LIFE - base of flask, get it with Bleeding and Corrupted Blood remove 2) SULPHUR - 40% increased Damage is always good, more Regen Life is very good and 50% reduced effect of curses on you is great 3) JADE - while we don't have too much Evasion Rating on Body Armour, it's very need for get good numbers of that 4) TASTE OF HATE - it's give phenomenal defense against elemental Damage. Also chance for avoid being Chilled and Frozen is nice 5) DIAMOND - for a lot of Crit Chance 
Spoiler
With Unique Boots we can have 2 Anoints
1) UTMOST MIGHT - best option for stacking Str.  2) PAIN FORGER - a lot of Crit Chance, we need it so much.  
Spoiler
Spoiler
* WARNING! Don't get link Frostblink with Automation, cuz it gonna crazy random teleport you around.
1) DAMAGE (6-LINK) Spark with Cast on Crit + Cyclone to trigger spell, also Faster Projectiles is crucial. Increased Critical Strikes is must have for get 100% Crit and Increased Critical Damage just for Damage 2) SECOND DAMAGE (3-LINK) Second Spark setup you have to put into Weapon. Faster Projectiles is crucial and Increased Critical Damage for Damage 3) SHIELD (2-LINK) Shield for over 2k is great addition to defense and with using Automation we don't have to worried about to recast it, but remember about cooldown time of this skill 4) MARK (2-LINK) Assassin's Mark for Crit on rare and unique is must have, with Mark on Hit you don't worried about cast it, you always apply that on hitting with Cyclone 5) POWER CHARGE SUSTAIN (2-LINK) On normal clear maps it's not a problem with keep max Power Charges on killing mosters, but we use Orb of Storms + Power Charge on Critical Strike for sustain these charges on single target 6) REGEN (2-LINK) Any Trap with Cluster Traps it will throw 3x Traps at one time, so one cast into enemies and you get 6% of bonus from Pyromaniac node 7) MOVEMENT Best movement skill for that setup, cuz you can use it even while you channelling Cyclone without stopping that 8) REGEN BOOST Trap gives Amazing boost to Life regen, so it will be very nice here 9) DAMAGE BOOST & FRENZY CHARGE GENERATION Blood Rage with increased Attack Speed for more trigger numbers for both Sparks, so it's free Damage. Also easy access to Frenzy Charges through the map 
Spoiler
1) Wrath - nice Damage scaling 2) Discipline - for Energy Shield sustain and later for activate mod from Watcher's Eye 3) Summon Skitterbots - free Shock + Chill effects. Also it's easy way for activated to High Voltage node for more Crit 4) Grace + Vaal Grace - defensive type, much of Evasion. Also Vaal version is nice for hot situations 
Spoiler
1) LEVEL
⦁ Keep Ice Trap on 1 lvl ⦁ Cluster Traps lvl doesn't matter ⦁ Every other gems get to 20 lvl 2) QUALITY + BONUS QUALITY ⦁ The most important - 2x Spark, cuz we got additional projectiles (+1 more for each 10%), then gems for Crit Chance and Mark on Hit for more flat Crit ⦁ Rest gems from Damage setup to maximizing Projectile Speed and Damage. Also Blood Rage for Attack Speed ⦁ Less important, but on later you can get % on them ⦁ For rest of gems it's not important too much or at all 
Spoiler
We are playing Saboteur, cuz main reason is Perfect Crime with Triggerbots skill. Also other nodes are useful too
 1) It's give a lot more triggered of Sparks, so it's main point of this Build. 2) Huge boost for Cooldown Recovery Rate, it's give next breakpoint for CoC gem significant improve defense with faster access to Steelskin. Also Frostblink has lower Cooldown Time, so it's awesome.  3) Defensive layer with reduced Damage taken. Cannot be Blinded is also nice.  4) We get 2 Immunes: Ignite and Shock. Also regen Life is amazing boost.  5) We have this Trickster node from 2x Forbidden Jewels. So big less hits Damage and Damage over time taken, it's huge for sustain.  
Spoiler
1) MAJOR - Solaris for defense on single target
 2) MINOR - Ralakesh for defense against DoT is nice.  
Spoiler
What type of mods will be hard
⦁ Cannot regen Life just destroying us ⦁ Less regen Life can be a bit painful ⦁ Less Cooldown Recovery Rate is very annoying, cause it's very lower your Damage ⦁ Suppress chance is unlucky might be dangerous against some moobs ⦁ Lower your action speed can suffers us too 
Spoiler
In gameplay is like typical Cyclone Cast on Crit, but mechanically it's just Spark
⦁ Keep spin up whole time ⦁ For harder moobs try activate and refresh Pyromaniac node every each 4 sec. with just one cast of Ice Trap into enemies ⦁ Cast Orb of Storms in moobs when you enter the map to fast get max Power Charges. Also casting it helps keep Power Charges on single target ⦁ Don't forget to cast Vaal Grace for extra defense ⦁ If you have in hard situation or you struggle with though mods on rare, just run, back off and wait for regen Life 
Spoiler
You can a bit improve our chance to success on these hard contents, annoying mods on map and also for fight on T17 maps, you do it
PANTHEON Pick Soul of Ryslatha for Life Flask charges  
Spoiler
Build is budget version, but if you have currency you can push it even more with these
⦁ Spark Nova gem 21 lvl - just pure more Damage ⦁ Support gems 21 lvl - another more Damage ⦁ The Stampede Boots - this not replica version has faster Cooldown Time for Frostblink 
Spoiler
I hope someone wanna try this Build, cuz it's so fun and enough for destroying T16 maps and be tankiness as well. SPARK is one of the most satisfying skill for mapping in whole game and using it with CYCLONE COC style is even more fantastic. I was put a lot work for every details. Guys if you have any idea else, what can I add to this Guide, just let me know and GOOD LUCK :)
