Deadeye/Berserker Low Life Voltaxic Spark/Vaal Spark

Put on your Tinfoil hats!
Disclaimer:
I have been debating making a version of the guide that is Zealot's Oath Based instead of Leech. This would take the Occultist Scion Ascendency along with Deadeye and drop some nodes that are south of the Shadow. The tree idea I have is as follows:

If my calculations are correct, that is a ~81 ish tree. This tree offers 4.8% es regen per second and if you take advantage of a Sulphur flask, you can get extra 5% (I think) from standing on the Consecrated Ground. Note: Put a second Energy from Within Jewel into the Socket near mind over matter to convert the life in the life/regen cluster to ES, as those nodes are taken for the es regen with ZO.

"

Low Life vs Life based on the other hand is a bit of a toss up. I have watched both Zizaran and Ziggys Life based version and they get roughly the same damage and have the benefit of life. I rarely get hit in maps unless I make a mistake with positioning, the damage is insanely good and off screens most things. Been doing twinned T9 and T10's with extra life and a single vaal spark kills the bosses while I take no damage. Even twinned gorge bosses aren't too hard.

Low Life has been awesome this league and I have had no trouble hitting high tier maps. If you want to play something other than the streamer popularized Life based Voltaxic Spark, look no further!

The following are must haves for this build:
Also get one of those Energy from Within Jewels to put in the socket below the melding cluster.

You can get away with using a Solaris Lorica but you won't have near the tankiness (Already kinda squishy). Voltaxic is a must because we need to be doing chaos damage to use the Poison Support Gem. This allows us to do massive damage on hit and over time and kill things very fast. We are also immune to reflect as Chaos damage cannot be reflected. If you are wanting the build to be Vaal Spark heavy and very effective with Vaal Spark, then get multiple Sacrificial Harvest Viridian Jewels. These can be corrupted from any rarity viridian jewel using a Vaal Orb. Not 100% chance to happen so it may take a while. They are expensive to buy, especially high rolls.

Leveling is easy with spark as it is one of the best leveling specs even for non end game spark characters. I will assume this isn't your first character of the league. If you are wanting it to be, then good luck ES gear is expensive.

Disclaimer: Borrowed some of the leveling strategy from Zizaran. You can watch him on https://www.twitch.tv/pcchild He plays a life based Vaal Spark/Spark with Voltaxic.
So some gems to have bought that you can't get yourself: Fire Trap, Lightning trap.

Good Leveling Uniques

Point - Alira - Kraityn/Alira

Reasoning is we need cast speed because we are using a bow end game. Also Frenzy from Kraityn because Victario's Acuity give Proj SPEED per frenzy charge! You could take Alira if you want for damage. I personally liked the proj speed for Vaal Spark.

This gear hasn't changed much since earlier. Sitting at 6100ES right now using drillneck.

Voltaxic is Self explanatory and explained above :)

The Vertex is a great item if you can pick up resists elsewhere. Lots of es and chaos res. Should cost roughly 10-15c for decent rolls in Perandus.

Drillneck is used when you don't need as much tankiness. Soul Strike is great because it gives us ES and Faster Start of recharge for our ES.

Victario's is BIS and highly recommended. Very affordable this league as well.

Low Life = better get a Shavs, also extremely affordable in comparison to past leagues.

Just looking for some flas ES and resists here for the time being.

Resists and as much es as you can on gloves

Resists and es on belt, Doryani's Invitation Lightning belt would also be an option.

I suggest some Rainbowstrides for starter boots as they give tri-res and decent es and are fairly inexpensive this league.

I also use 2 Sacrifical Harvest jewels for extra chance for vaal souls on kill. The aren't required but they are great for keeping vaal spark up more often.

Rare ES gear is quite expensive (Normal for this to be the case). So expect to spend a bit on your end game gear. If you are playing SC you can get away with sub par gear until higher levels and get better gear then.

Jewels are pretty straightforward. You have two routes you can take.
Route 1: Get 2-3 Sacrificial Harvest Jewels and perm vaal spark. Best done in open maps and you'll get used to what maps you can and can't do it on later.
Route 2: For maps you can vaal spark constantly, you can swap in rare jewels with Proj Damage/Chaos damage. These double dip with poison damage. (Proj Damage = Chaos damage) >(Spell damage/Lightining Damage)

With both you will want an Energy from Within below the Melding cluster between Witch and Scion.

I used to swap flasks a lot and I have landed on these being my favorite and most used.

Vaal Spark: In Voltaxic because it makes colors easier(5L)
Vaal Spark - Spell Echo - Pierce - Poison - Void Manipulation
Spark: In Chest Piece(5L)
Spark - Spell Echo - Pierce - Poison - Controlled Destruction/Void Manipulation if you get 3 green somehow :)
Aura Setup 1(3L)
Blood Magic - Discipline - Clarity (Keep an eye on levels and if you have a Vertex helmet then put them in there for free +1 gems)
Aura Setup 2(3-4L)
Herald of Thunder - Curse on Hit - Temp Chains/Enfeeble/Vulnerability(pick one) - Wrath (Wrath can be by itself as it can't actually curse)
CWDT(2L)
CWDT - Immortal Call
Single Socket Gems
Wrath (If you don't have it in the Herald Link from above)
Blink Arrow
Flame Dash(Can add faster casting if you have the link for it)
Portal gem(Optional but very nice)
Golem (I use Chaos golem mostly because it uses blue socket)

As you can see, the build is strapped for links so if you have 6L bow or chest piece you will have to make a sacrifice somewhere. Maybe drop a movement skill or golem or get a ring with a socket in it. The Current Gear section has the way I have the gems set up right now.

Currently running level 20 clarity and Discipline on Blood Magic to put me on low life. Then I am using Herald of Thunder, Wrath, and Arctic Armour on mana.

So many people have come in here and said "Why no Vaal pact?" I wasn't convinced it was great until I hit high tier maps and steamrolled Atziri with Vaal Pact. My mobility is far too high to use the Sorrow of the Divine flask very well and Zealot's Oath is too far away. Thus I have landed on taking Vaal Pact now. I didn't take it till 91 and its definitely not required I just found it to be simpler this way and with Atziri's Flask it is a lot of leeching going on.

Other than that node the rest is pretty much self explanatory. Getting power charge and a frenzy charge to complement our Victario's Acuity and we get things like Pain Attunement and Ghost Reaver because we are low life.

Certainly keep in mind that this is just the tree that has performed amazing for me and is not necessarily the best tree EVER. Make changes and see how you like them. Regrets are not super expensive and I certainly don't have the same tree I started with. Good luck out there!

We are a Scion because of one very important reason: Deadeye is amazing. So we take Deadeye and Berkserker for sick damage and leech. This allows us to focus on getting good ES on gear.
