Vaal Blight/Essence Drain
CI Trickster Build

Updated for Patch 3.14

The Best Crafty Guides by Odealo

Estimated budget: medium

Blight is a channeling type of Spell similar to Scorching Ray or Lightning Tendrils, it deals Chaos Damage Over Time, gaining more stages the longer it is being Channeled. The Spell applies a debuff which deals the Damage over Time, much like Poison but it can stack up to 20 times. The spell itself does not Hit, so it limits our choice of Support Gems. Blight due to its Channeling nature is commonly used against the toughest opponents, for killing the lesser enemies you'll find in great numbers when mapping, use Essence Drain with Contagion. These two Spells synergize very well with each other - Essence Drain provides the Damage and Regenerates Life (ES with Zealoth's Oath) and Contagion makes both Spells spread to other enemies when one of them dies, basically killing everything on the screen. 

The build is surprisingly similar to Toxic Rain - the mods you crave the most are Chaos Damage Over Time. There are however some key differences - Toxic Rain is an Attack, not a Spell. You'll be using Chaos Inoculation which grants you immunity to All Choas Damage. Ghost Dance and Escape Artist Ascendancy Kesyones work really well with Energy Shield and Blocking/Evading/Dodging Hits. Patient Reaper is another Defensive Keysone provided by Trickster Ascendancy - it recovers a lot of your Life and Mana. The build is Flexible - it requires no Unique items and even the Weapon types and Keystones differ from Player to Player.

1. Gameplay

When mapping - use Contagion and then Essence Drain on a pack of mobs. With the increased density of enemies, the effectiveness of this strategy goes up as well since the range it can spread is limited. The enemies will die almost instantly. To deal with Bosses use Blight and the Vaal version of it. Vaal Blight is especially good here since it doesn't require being Channeled and so allows you to be more mobile. For dodging - Flame Dash seems like the best option.

2. Build's PROS & CONS

3. Leveling tips

At some point during leveling, you'll have to switch to CI. Make sure you have enough ES on your items and then Respec Skill point on your Tree. You can safely start with Essence Drain as your Main Skill as soon as level 12 and use it with Contagion, it's good with the right gear. Before you're level 12, use Bane. There aren't many Unique items that can help you with leveling except the generic ones. I suggest using Essence of Envy on Jewellery for more Chaos Damage.

Suggested leveling Gem setups:

Essence Drain setup
	Essence Drain - Essence Drain thanks to it spreading through Contagion is an amazing Spell for leveling as well
	Efficacy Support - increases your Spell Damage and Damage over Time, whereas, both apply to Essence Drain
	Void Manipulation Support - increase Chaos Damage dealt by Supported Skills
	Controlled Destruction Support - grants very high bonus Spell Damage at the cost of reduced Critical Strike Chance which is irrelevant for Essence Drain as it's purely DoT build

Blight setup
	Blight - a Channeling Spell you can start using right away. It's used to deal additional Damage while you already have the ED's DoT applied to an enemy
	Infused Channeling Support - increases your Damage while Channelling but also grants Infused buff for extra DPS and defensive bonuses
	Efficacy Support
	Void Manipulation Support

Aura setup
	Malevolence - use for more Damage over Time. The best Aura for this and pretty much any other DoT build
	Clarity - Clarity will resolve your mana issues if you happen to have any

Bandits:

KIll all three Bandits for two additional Skill Points

Leveling Skill Trees:

33 Points Skill Tree
Go for Atrophy by taking Entropy, Growth and Decay, and Arcane Expanse

68 Points Skill Tree
This is how your Skill Tree could look like just before you transition to pure ES. Take some more Maximum Life and for a path to Zealoth's Oath.

Recommended leveling items:

Le Heup of All - a rung such as this is great for leveling due to Elemental Resistances, Attributes, and a small Damage increase

Adds 1 to 4 Physical Damage to Attacks +(10-30) to all Attributes (10-30)% increased Damage (10-30)% increased Rarity of Items found +(10-30)% to all Elemental Resistances

Goldrim - use Goldrim for more Elemental Resistances

+(30-50) to Evasion Rating 10% increased Rarity of Items found +(30-40)% to all Elemental Resistances Reflects 4 Physical Damage to Melee Attackers Level Requirement reduced by 100 (Hidden)

Tabula Rasa - saves a lot of trouble when looking for the right sockets early in the game

Item has no level requirement and Energy Shield (Hidden) Item has 6 White Sockets and is fully linked (Hidden)

4. Final Skill Tree, Ascendancy Points, and Pantheon

Final Skill Tree:

118 Points Final Skill Tree (doesn't include Cluster Jewels nor Thread of Hope)
118 Points Path of Building (PoB) link

Ascendancy points:

Preferably in that order:

1. Patient Reaper
2. Prolonged Pain

6. Gear Setup

There is not a single Unique gear piece worth recommending, with exception of Atziri's Step, that's shy the price can vary from cheap to extremely pricey. With cheap gear, you'll be able to run red Maps with ease, but with the expensive one, it is quite likely to survive most hits on T16 maps with more than 10k ES. There are three stats to look for: Energy Shield, Elemental Resistances until capped, and Chaos Damage over Time (that includes Chaos Damage and Damage over Time).

Our recommended items will:

1. Cap your resistances at 75%
2. Provide you with enough DPS and ES to start mapping

(Helmet) Rare Helmet - get as much Energy Shield as possible, for the remaining mods you can additionally look for are of course Elemental Resistances and "Nearby Enemies have -#% to Chaos Resistance"

Min. requirements: +40 to maximum Energy Shield 120% increased Energy Shield Optional affixes: Elemental Resistances Nearby Enemies have -#% to Chaos Resistance

Helmet enchantments: 24% increased Blight Area of Effect 40% increased Blight Damage Blight has 30% increased Hinder Duration 40% increased Essence Drain Damage 24% increased Contagion Area of Effect

(Weapon) Rare Wand - Look for Spell Damage, Chaos Damage, and Damage over Time. It is very useful to have socketed spells automatically trigger every 8 seconds. The best approach is to craft "Can have up to 3 Crafted Modifiers" since you can craft Chaos Damage over Time as well.

Min. requirements: +1 to Level of all Spell Skill Gems Trigger a Socketed Spell when you Use a Skill, with a 8 second Cooldown (crafted) 50% increased Spell Damage Optional affixes: +1 to Level of all Chaos Spell Skill Gems +#% to Damage over Time Multiplier +#% to Chaos Damage over Time Multiplier

(Shield) Rare Shield - Intelligence-based Shield is able to contain a lot of Energy Shield but not much else. Chance to block and Elemental Resistances are useful here.

Min. requirements: +100 to maximum Energy Shield 80% increased Energy Shield Optional affixes: Chance to Block Chance to Block Spell Damage Elemental Resistances increased Area of Effect

(Body Armour) Rare Body Armour - Energy Shield and Evasion Rating are the most important stats to look for in Body Armour, that's why it's a good idea to craft additional Quality, especially when your base provides both - ES and Evasion.

Min. requirements: +130 to maximum Energy Shield 80% increased Energy Shield Optional affixes: Increased Evasion Rating and Energy Shield Elemental Resistances +#% to Quality Evasion Rating

(Boots) Rara Boots - Movement speed - increased by around 30% is a must-have. Focus more on Elemental Resistances than ES here, Boots are usually not the place to look for ES.

Min. requirements: +30 to maximum Energy Shield 30% increased Energy Shield +70% to Elemental Resistances +25% increased Movement Speed Optional affixes: % chance to gain Onslaught for 4 seconds on Kill Cannot be Frozen % chance to avoid Projectiles

(Boots) Atziri's Step - use this pair of Unique boots if you need a cheap and solid defensive option. They Provide no ES nor Elemental Resistances - find yourself decent Rare Boots if you lack these stats.

180% increased Evasion Rating +(55-75) to maximum Life 30% increased Movement Speed (14-16)% chance to Dodge Spell Hits

(Gloves) Rare Gloves - Elder/Hunter Suffix and Warlord's Prefix can give you some Chaos Damage over Time increase. You can use Essence of Delirium for the "Socketed Gems deal 30% more Damage over Time" mod and use it with Essence Drain, which is a highly recommended move.

Min. requirements: +16% to Chaos Damage over Time Multiplier Optional affixes: Socketed Gems deal 30% more Damage over Time Increased Energy Shield Elemental Resistances +# to Level of Socketed AoE Gems +# to Level of Socketed Projectile Gems +# to Level of Socketed Intelligence Gems

(Belt) Rare Crystal Belt - Crystal Belt gives you 80 ES from Implicit Mod for free, so it's a base you should use. It's also a good place to look for Elemental Resistances - around 70% in total.

Min. requirements: +120 to maximum Energy Shield (including Implicit) +70% total Elemental Resistance Optional affixes: Evasion Rating Increased Maximum Energy Shield Increased Energy Shield from Body Armour Regenerate # Energy Shield per second while a Rare or Unique Enemy is Nearby

(Amulet) Rare Amulet - Hunter's Influenced Amulet allows you to increase the Level of all Choas and Intelligence Skill Gems and you can roll Chaos Damage over Time Multiplier here as well so keep that in mind when looking for bases. Look for Strenght as Implicit for your Shield Charge and Immortal Call Gems

Min. requirements: +30 to Strenght +50 to maximum Energy Shield +60% total Elemental Resistance Optional affixes: Increased Maximum Energy Shield Increased Chaos Damage Channelling Skills have -# to Total Mana Cost

(4-6)% increased maximum Energy Shield (4-6)% increased maximum Life (4-6)% increased maximum Mana <Two or Three random aura modifiers>

(Jewel) Spreading Rot - Usually, just one Spreading Rot is enough. Due to its extremely low price, it's the best place to look for Corrupted Blood Immunity as Corrupted Implicit
