[2.1] Voltaxic Rift Crit Poison Spark Totems - Safe and potent for high lvl maps with all mods

Short Version!
Pros: Damaging, safe, tight maps are awesome.
Cons: Bow is kinda expensive, can't leech, and open maps are less awesome.

Long version
Pros:
-Great damage. The ability to get double duty from nodes is so powerful against bosses and rares.
-MoM/Dodge/Evasion is surprisingly safe. 54/56% Dodge/Spelldodge with Hyrri's Ire and corrupted Atziri's Step.
-You can run any map mod. (No Regen and Blood Magic interact poorly with MoM, but you are totally fine even with just one hybrid flask.)
-Spark crushes in narrow corridors.
-Chaos is not resisted by many enemies. 100% of damage is chaos.
-Totems and Sparks can be used around corners to deal with strong ranged enemies. Melee are even easier to avoid, as you don't need to stop moving to kill them.
-Totem casters are immune to reflect and (mostly) deal with corrupted blood stacks.
-Voltaxic makes chaos shock. This is a crit build, so this happens regularly.
-You can achieve 100% pierce chance without the support gem.
-Blink Arrow is a superior move skill.
-You can use a utility 5L/6L in your bow to apply curses or do anything you want with (I like Blind and Life on Hit). The gem slots are very, very open.
-Each Spark volley resets "shotgun memory" for the whole volley on every wall bounce for even one projectile (Translation: every time one of the 8 projectiles hits a wall, all 8 can hit every enemy again.)
-Leveling is pretty optimal using Physical EK with Poison (and maybe Apep's Chaos lvl 1 Spark totems at 62 until late 70's) with only slight changes in the tree when you swap over to a Spark build.
-You have the option to negate your MoM damage with Rallying Cry and the threshold gem, Spirited Response. Rallying Cry is already very good for this build due to double-dipping.

Cons:
-Voltaxic is expensive! It took a bit for Poison to catch on, but did it ever.
-Spark is worse in wide open spaces.
-You cannot leech.
-You cannot reduce the resistance of the few enemies that are chaos resistant.
-Totem Casters only get inconsistent value from "on kill" effects (Silver lining: Poison kills go to you, not your totems!), making it harder to use Assassin's Mark to get power charges unless you cull on your utility attack.
-You have lower than usual mitigation. Arctic Armour/Enduring Cry can make it better, but they take away from what MoM and Rallying Cry can do for this build.
-Projectile Weakness is not very party/melee friendly unless your buddies are on board.
-This build wants to use several uniques. Life, resists, and stats on gear are harder to balance, especially while trying to cram in crit stats.
-Voltaxic has a high DEX requirement (212) that is difficult to work in. Fortunately, if you can get to 197 DEX for Hyrri's Ire, it will supply the remaining DEX to get to 212. STR is rough too.
-Getting life to HC levels is quite difficult for this build, due to the stretch between Acro and Ancestral Bond. A non-crit variant is much more reasonable for it, but the damage is much lower.

Bandits
Oak-[Alira or Point]-[Kraityn > Alira > Point]
Flat life is tough to come by due to uniques so Normal is an easy pick. The tree is so tight that I might ditch the 5% cast speed in Cruel. I like the Frenzy charge best for Merciless, but I could even see taking the point for some setups. Power charges are tough to sustain, but a setup that does could want it over the Frenzy charge.

Final Tree
The two remaining life nodes in the Witch area are first. The jewel socket below MoM is second. Frenzy charges, Power Charges, or Whispers of Doom seem to be the best additions after that.

Alternatively, going along the top of Witch lets you take Corruption and Whispers of Doom while making the Witch jewel socket almost optimal for a 45% Eldritch Knowledge.

Note the absence of crit and the addition of physical nodes. Physical EK with Poison clears rather well and there are only a few points that need to be changed once you swap into one of the Chaos variants. Then make a break for Ancestral Bond and slam into all the adjacent crit nodes.

Required:

The entry fee for this build. Suck it up. Play Dual Apep's until you can afford one.

Recommended Dodge Gear:

This is my recommended defensive package. 54%/56% dodge/spelldodge and decent evasion gives your mana time to recover between hits.
[Note: the most tempting chest is of course Soul Mantle in order to get a third totem. I'll talk about this variant below in the options section, as my buddy has developed some serious tech for a different totem build.]

Damage Gear:

This quiver is almost perfect for this build (it has T2 projectile speed and crit chance). Only life helps for suffixes, the other two can be garbage. Alternatively, if you decide one Fork is more desirable than 100% pierce, you can go with Rigwald's Quills http://pathofexile.gamepedia.com/Rigwald%27s_Quills. I have not tried it, but losing life and taking a projectile speed hit does not seem worth it to me. I really like keeping the projectiles live after hitting every time and giving them some more reach with projectile speed. The projectile damage double-dips, however, so that could be a really good reason to try it out. It might interact positively with 50-60% pierce chance from Projectile Weakness. I'm just not sure.
I have yet to test with Maligaro's, but I've been wearing Winds of Change since low levels. It's stellar and has a little life. Maligaro's DEX might be just as good though to help fix the gaping DEX hole.

Stat/Resist Fixers:

Life. Resists. Stats. Crit. Mana Regen. As much as you can afford. Upgrade, upgrade, upgrade to take pressure off the tree and work in more damage and survivability.

Jewels:
I currently run one Rain of Splinters and one Life/Chaos Damage/Resist jewel. I have not yet reached the third socket.
http://pathofexile.gamepedia.com/Rain_of_Splinters
The Rallying Cry threshold gem, Spirited Response, is very useful for this build. You can use it in the Witch socket already. It takes a bit of twisting to get it to work with the socket below MoM. You could also theoretically take the Templar socket if you wanted to trade some other points for the power charge and Light of Divinity or take the Shadow socket by taking the outside route to Atrophy and that power charge, but those take even more wrangling. The upside is that while Rallying Cry is active, your MoM and Spirited response interact together to effectively negate 10% damage per jewel (up to 30%).

5L/[6L]
Spark-Spell Totem-Poison-Void Manipulation-Faster Projectiles-[Controlled Destruction]
I could also see using Increased Duration, Added Chaos (over Added Lightning), Faster Casting, or Crit Damage if you wanted to try things out. (I need to rerun the numbers now with my real stats to see if this is still optimal, but the above is what I found was best in theorycrafting.)

5L/[6L]
Frenzy-GMP-CoH-Projectile Weakness-Blind-[Life Gain on Hit/PCoC/Assassin's Mark/Enfeeble]
I've been a big fan of Blind, as it amplifies the power of my dodge/evade/MoM defense. However, I ditched PCoC for it, so I am not currently making power charges. If I worked in another curse via a Doedre's Ring or Whispers of Doom, it would be either Assassin's Mark or Enfeeble. Assassin's is not ideal as you only get charges from the poison kills; you could replace Blind in the 6L with Culling and that would ensure power charges. You could even set up further around the culling strike and use the Increased Rarity gem. Man, I miss Power Siphon.

4L
Vaal Spark-Trap-Void Manipulation-Poison
Set the trap on a strongbox or Stone Circle and Blink away to curse. Very effective, but remember you must use the Trap support to deal damage!

4L
Rallying Cry-Blink Arrow-Increased Duration-Faster Attacks
Just doubling up on duration for blink clone and warcry. Not a necessity. Rallying cry gives you double-dipping damage for poison and a chunk of mana regen. Very solid for use with MoM. Blink Arrow is my new favorite move skill.

4L
Clarity-Flame Golem-Blind-[Whatever]
A lot of room to play with in these links. Maybe better to split 3 and 1 for CwDT-IC-Golem and Clarity. Or do CwDT-IC-Duration-Rallying cry to use the duration more effectively (keep in mind that CwDT will not trigger the warcry; this is just to share the Duration gem). Flame Golem's buff is great, as the damage will double-dip. Chaos Golem would also be a solid option.

Note on Reservation:
I prefer to have a large part of my mana available for MoM, which is why I only normally reserve Clarity. You can expand your damage immensely by also reserving the Wrath aura, which give you 21% more lightning damage, which will affect your initial hit, but will only help your poison insofar as your initial hit is higher. I have a buddy that I often play with that runs it and this build does tons more damage when I stand next to him. You could lower your MoM effectiveness to run Wrath or you could even cut MoM entirely and use AA/Enuring Cry or some other form of mitigation. Now I find that I don't need this damage, but it is nice to have. It might be worth considering running it when not in a dangerous zone and turning it off when you think you might need the additional mitigation.

Under Construction
Why is Poison so busted?

Why not just use the bow?

Why Spark?

Why Spell Totems?

Why Crit?

How does Spark's memory resetting work?

Offense
Run Wrath (or find a buddy that does).
*See note at the bottom of the Links section.

Add a Searing Bond totem.

Use Soul Mantle.
Three big reasons you might give up a more defensive chest option for Soul Mantle are 1. You can get a 3rd totem or 2. You can skip Ancestral Bond and un-stretch your tree and 3. You get a "free" Spell Totem link that puts you one link ahead. All are extremely desirable, but you lose some serious defenses in the form of 10% dodge/spelldodge and 2000 base evade. You also have to deal with the curse drawback. Even from the relative safety of a totem strategy, this is going to add danger.

Ditch other defenses for more raw power.

Defense
Get more life.


Prefer not to use Mind over Matter? Run Endurance Charges and Arctic Armour instead.
