Basic Skills
During Act 1, the Build relies on the Basic Skills of the Wand / Staff for added Single Target Damage
Preferably use a Staff to get
Firebolt or
Lightning Bolt or a
Withered Wand for
Chaos Bolt.
Socket Unleash into your Basic Skill for bossing and in
Contagion otherwise.
Entangle
Entangle is our 'Budget'
Essence Drain from the Primalist Section. It is a Tier 1 Spell and can be used right from the start. Use it for early Clear and once every 8 Seconds during Boss Fights until unlocking
Essence Drain. It places a Fisure in the casting Direction and acts as a pseudo Damage over Time Effect. While it is not spread by
Contagion, 1-2 cast do enough Damage to clear a White Pack and spread the
Contagion.
Essence Drain & Contagion (Weapon Set 2)
Essence Drain is the primary Skill of the Build, used for Bossing before Level 14 and for Clear throughout the Campaign. It deals a little Chaos Damage on Hit and applies a Native Chaos Damage over Time Effect for 4 Seconds. One noteworthy interaction is that Chain I only reduces the Hit Damage, not the DoT Damage, so it is 'free' Coverage.
On its own, it is very simple, but combined with
Contagion it unlocks it full Potential.
Contagion applies a weak Dot to a single Enemy, which will spread itself and all other Chaos DoTs to nearby Enemies when the afflicted Enemy dies. With each spread, the
Contagion DoT increases in magnitude. Most importantly, this spreads the powerful DoT of
Essence Drain.
Until Quality is applied, to
Contagion, it is recommended to support it with Unleash. While we technically only need to infect one Enemy with Contagion and Essence Drain, hitting one enemy with both skills can be a bit annoying. Supporting them with Unleash and Chain allows for a much smoother Feel and clear.
Bonestorm (Weapon Set 1)
Far into the Endgame
Essence Drain and
Dark Effigy have enough Single-Target Damage to deal with Bosses, we don't have time to watch them slowly die. We want quick, instant Death for every Boss standing in our Way into the Endgame.
Bonestorm solves that for us. It is a Channeling Skill that charges up an array of up to 20 Bone Spikes. Once stop Channeling all Spikes fire in the targeted Direction. Each Bone Spike deals separate damage and applies their Impale Stack. Impale takes 30% of the Physical Damage and stores it in the Debuff. Each Attack against an Enemy with an Impale Stack will consume one and apply that Damage to the Attack as Base Damage, scaled up by increases and Crit.
While intended to be used with Attack-based Minions or a 2nd Player using a quick Hitting Attack Skill, the best Way to proc your own Impales is Living Lightning. By either using a
Orb of Storms or having a
Storm Rune to grant
Bonestorm any amount of Lightning Damage, we spawn up to 5 small Lightning Orbs, which use a Chaining Lightning Attack. They quickly consume all the Impale Stacks we build up with Bonestorm.
Dark Effigy (Weapon Set 2)
One of the latter skills of the Occult Skill Section is
Dark Effigy, which actually does nothing on its own. It requires Chaos DoTs on Enemies from other Skills like
Essence Drain,
Contagion and Poison I.
This Skill is also our first 5-Link and will take over Single Target Damage as we get into the Endgame. That said, during the campaign, this is optional, but it should definitely be set up in advance.
Spirit Gems
Arctic Armour or Ravenous Swarm
With 30 Spirit in the Early Stages of Campaign, we have 2 decent Options.
The Defensive option is
Arctic Armour applying a small Cold Hit when attacked which can chill and freeze the Attackers.
The Offensive option is
Ravenous Swarm which regularly spawns a Swarm of Insects applying a small Poison on Enemies. This Poison can be spread by
Contagion and can break Armour if linked with Corrosion.
I currently recomend
Arctic Armour, but
Ravenous Swarm is a great offensive Option if you are confident in your Dodge Roll Skills.
Blasphemy
After defeating Ignaduk, we get 60 Spirit and can use
Blasphemy with either
Temporal Chains or
Despair.
Temporal Chains slows enemy down as they aproach us and prolongs the Duration of our Debuffs and DoTs on them.
And
Despair reduces their Chaos Resistance, making them take more Chaos Damage over Time.
I recommend
Temporal Chains for the same Reasons above.
Despair is theoretically better for Advanced Players.
