Destiny 2 Warlock BuildIonic Charge Mayhem

Subclass: Stormcaller (Arc)

• Super: Chaos Reach Chaos Reach is a no-brainer for our Arc super right now. It will absolutely destroy hordes of adds and simply melt chunks of health from bosses. With the rest of this build, you should be getting Chaos Reach frequently.
• Class Ability: Healing Rift This will be our emergency healing option for the build.
• Movement Ability: Burst Glide You can swap this with whatever movement ability you're most comfortable with.
• Powered Melee: Ball Lightning Ball Lightning is arguably the most powerful Arc melee. Additionally, we'll be Amplified a ton with this build, so we should benefit from the additional lightning strikes that Ball Lightning releases while Amplified. We'll also be using the Flashover Artifact Perk that will buff all of the lightning strikes.
• Grenade: Pulse Grenade, Storm Grenade, or Flashbang Grenade Our choice of Arc grenade will come down to personal preference. Pulse Grenade feels more immediately impactful and has a nice duration. Storm Grenade can cover groups of adds, and while short, can do some decent damage due to the lightning strikes and the buff to them from the Flashover Artifact Perk. Another surprisingly good option is the Flashbang Grenade, which can do some damage, but also Blind nearby targets, which can feed into our build by applying the Blind debuff which can help stack Bolt Charge based on the Dielectric Artifact Perk. Blinding enemies can also help with our survivability since those enemies won't fire at us while Blinded.

Our aspect selection is the foundation for our Ionic Traces and Bolt Charge focus. Plus, we get to use a really fun new aspect with the Ionic Sentry that was released with Heresy.

• Aspect: Ionic Sentry For our aspects, we want to start with the brand new Ionic Sentry, which will allow us to charge up an Arc turret by killing enemies with our Arc weapons or Arc abilities. In the rare case that we run out of ammo for our Arc Special or Heavy ammo weapons, kills with Kinetic weapons will also charge the Ionic Sentry. When we deploy our Ionic Sentry, we'll Blind anything in the vicinity, including Unstoppable Champions. Since we don't have Devour or particularly strong healing with this build, Blinding groups of enemies will decrease the pressure on us. Once deployed, the Ionic Sentry will then chain lightning between nearby enemies and grant stacks of Bolt Charge on every hit. Bolt Charge is one of the synergies that we'll be leaning into because at maximum stacks, any ability damage will generate a lightning strike, which is going to add to our Arc mayhem. As a bonus, receiving a stack of Bolt Charge grants us melee energy, which is another way that we'll keep that ability up and available to spam.
• Aspect: Electrostatic Mind The second aspect we're going with is Electrostatic Mind. We're using this aspect to create tons of Ionic Traces to keep our super and other abilities charged up as well as to get Amplified. With this aspect on, any Arc ability kill or killing any Jolted or Blinded target will create an Ionic Trace. Since we'll be spamming our abilities, including an Ionic Sentry that is Blinding enemies when we deploy it, we'll be getting a lot of Ionic Traces which is going to help us keep our abilities available to spam.

Our fragment selection is where we really amplify the synergy between Ionic Traces and Bolt Charge for this build.

• Fragment: Spark of Discharge We're starting off with Spark of Discharge so that our Arc weapon final blows create more Ionic Traces. Any time we collect an Ionic Trace, we're going to get a stack of Bolt Charge as well.
• Fragment: Spark of Ions We're also going to use this fragment because of the focus on Ionic Traces. This fragment will create an Ionic Trace any time we defeat a Jolted target or defeat a target with a Bolt Charge. Ionic Traces stack Bolt Charges; Max Bolt Charges unleash lightning; Bolt Charge final blows create Ionic Traces; Cycle repeats.
• Fragment: Spark of Frequency This aspect provides a few benefits, but the one that we're focused on is the effect it grants while we're Amplified. While Amplified, we're going to get increased stacks of Bolt Charge from all sources. Since we're running Electrostatic Mind, we'll get Amplified every time we collect an Ionic Trace, which is going to be nearly any time we're in combat.
• Fragment: Spark of Shock or Spark of Beacons For our last fragment, we have some flexibility depending on the content that we're playing. If we expect Overload Champions, a good option is Spark of Shock. With Spark of Shock, our Arc grenades will Jolt targets, which can Stun Overload Champions. Jolt also feeds into the Spark of Ions which can help increase Bolt Charges. Another option is Spark of Beacons, which is generally good all around, but especially strong with lower level content or content with a lot of adds or trash mobs. With Spark of Beacons, any Arc Special or Heavy ammo weapon final blows while we're Amplified will create a Blinding explosion. Since we'll be Amplified any time we collect an Ionic Trace thanks to Electrostatic Mind, we'll be Amplified nearly any time we're in combat. And since we're focused on our Arc weapons when not spamming our abilities, we should be able to create a lot of Blinding explosions. Again, we don't have Devour or particularly strong healing options with this build. So creating Blinding explosions from our Arc weapon kills can help keep the pressure down.

• Exotic Armor: Geomag Stabilizers

For our Exotic Armor, Geomag Stabilizers is key. Not only will it extend the duration of Chaos Reach for us, but collecting Ionic Traces will also charge Chaos Reach. Since we're going to be creating tons of Ionic Traces, we should get Chaos Reach extremely often. As a bonus, it's also going to allow us to sprint when we're near max Bolt Charge to grant more stacks of Bolt Charge.

Since we have a strong ability loop based on Ionic Traces, we can focus our armor mods on ammo economy and healing/survivability. We'll use Armor Charges to tie these mods together because we can rely on having a plentiful stream of Ionic Traces to feed into Elemental Charge.

• Helmet: Special Ammo Finder (x2), Harmonic Siphon For our helmet, our priority is 2 Special Ammo Finder mods to help with ammo for Coldheart. If you're not running Coldheart, Heavy Ammo Finder mods might be a better choice. If you have the extra energy capacity, throw on a Harmonic Siphon to create Orbs from all of the Arc weapon final blows.
• Gauntlets: Harmonic Loader (x2), Firepower We're going to use two Harmonic Loaders to help with the Arc weapon reload speeds since this is a very run-and-gun style of build. Our last ability (if we have room) is Firepower to create Orbs on grenade final blows, which will hopefully be often.
• Chest Armor: Resistance Mods Match your resistance mods to the threats and damage types in the content you're playing.
• Leg Armor: Elemental Charge, Recuperation, Arc Weapon Surge Elemental Charge is our most important mod on the leg armor, as it will allow Ionic Traces to grant an escalating chance to give us an Armor Charge. We are creating a ton of Ionic Traces, so this should give us plenty of Armor Charges when we're in combat. Next, we'll use Recuperation to help us replenish our health by picking up Orbs. Lastly, we'll use an Arc Weapon Surge to also gain Armor Charges on Orb pickup, as well as boost our Arc weapon damage when we have Armor Charges. We shouldn't have to worry about the decaying Armor Charges since we'll have so many Ionic Traces feeding into Elemental Charge.
• Class Armor Item: Font of Restoration, Powerful Attraction, Healthy Finisher On our class armor we'll be using Font of Restoration to boost our recovery with Armor Charges. Powerful Attraction will help us pick up Orbs when we cast our Healing Rift. Healthy Finisher will give us the ability to use a Finisher to gain some health if we need. If we find that we're struggling to keep Armor Charges (we shouldn't with the sheer amount of Ionic Traces that will feed Elemental Charge), we can swap Powerful Attraction out with Time Dilation to extend the duration of our decaying Armor Charges.

1. Resilience
2. Discipline
3. Strength
4. Recovery
5. Intellect

6. Mobility

As with any build, we want to prioritize Resilience first (tier 10). From there, it won't matter quite as much since we'll be getting so many Ionic Traces to restore our abilities. However, we'll prioritize Discipline second, and Strength third. Because of the Ionic Sentry Aspect, we'll get melee energy back every time we stack a Bolt Charge, so it makes more sense to prioritize Discipline for our grenade energy over Strength. Since this is a run-and-gun ability spam style of build, Recovery isn't a top priority since we should only be using our Healing Rift in emergencies and we've covered health in our armor mods. Intellect also won't matter to us since we're running Geomag Stabilizers and the plethora of Ionic Traces that we'll be creating will keep Chaos Reach charged up for us quite often. We'll also get Amplified every time we collect an Ionic Trace, so Mobility isn't a priority at all.

We want to prioritize the use of Arc weapons in both the Energy and Heavy slots. There are some really strong suggestions here, but you can always experiment with others.

• Energy Weapon: Coldheart Ideally we want to run Coldheart for our Energy Weapon. Coldheart has the Longest Winter trait which will generate Ionic Traces for us when hitting the high-damage state. Since it's an Arc Special ammo weapon, it also works especially well with Spark of Beacons. We'll use a couple of Special Ammo Finders mods to help with ammo economy.
• Alternate Energy Weapon: Lodestar If Special ammo supply is a problem, a strong alternative for the Energy weapon slot is our Heresy seasonal Exotic weapon, Lodestar. While Lodestar won't give us quite as many Ionic Traces as Coldheart would, it can give us a couple of other benefits. Final blows while ADS (aiming down sights) with Lodestar can detonate Blinding explosions. The alternate firing mode of Lodestar can also apply Jolt, which compliments the Spark of Ions and can at least give us one additional way of creating Ionic Traces while using Lodestar.
• Heavy Weapon: Watchful Eye (with Jolting Feedback) We can run any Legendary Arc Heavy ammo weapon here, but a strong suggestion is a God Roll Watchful Eye, our Heresy seasonal machine gun. The God Roll here is an Overflow/Jolting Feedback combo. Overflow can keep ammo in good supply since picking up Special or Heavy ammo will refill and overfill the magazine from reserves. But the real star here is Jolting Feedback, where dealing repeated damage with the weapon will inflict Jolt at an increased rate. When we're Amplified, Jolt can be applied even faster, and we should be Amplified often due to Electrostatic Mind. Jolt will again work well with Spark of Ions to create those Ionic Traces that we're after. If you don't have Watchful Eye, substitute your Heavy ammo Arc weapon of choice giving priority to Jolting Feedback when you can.
• Kinetic Weapon: Dealer's Choice Run whatever Kinetic weapon suits the content you're playing and your individual playstyle. I suggest a Primary ammo weapon if you're running Coldheart in the Energy weapon slot, or a Special ammo weapon if you're running Lodestar.

We mostly want to take advantage of the Arc based Artifact Perks. Prioritize these and fill in the rest to suit the content you're playing and your playstyle.

• Overload Machine Guns Aside from Stunning Overload Champions with our machine guns, this perk can also Exhaust targets, which will play into a couple of additional Artifact Perks.
• Overclock and Load Overclock and Load will benefit our weapon handling and reload speed as we should be Amplified and/or have Bolt Charge most of the time.
• Dielectric Dielectric will grant us extra Bolt Charge when we defeat Arc debuffed targets, like those that are Blinded or Jolted from our Ionic Sentry, Arc grenades, and Arc weapons.
• Flashover Flashover will allow us to become Amplified when we reach maximum Bolt Charge stacks. We should already be Amplified often, but this will add another possible option to become Amplified while also buffing lightning bolt damage, like those from our Ball Lightning powered melee.
• Defibrillating Blast Defibrillating Blast will give us maximum stacks of Bolt Charge when we Stun a Champion. It will also trigger an Arc bolt that heals us and Jolts any enemies that it damages.
• Photonic Flare Photonic Flare will allow us to release a Blinding burst when we defeat Exhausted or Severed enemies with our Arc damage. This perk will mostly rely on our fireteam applying Exhausted and Severed to targets, unless we can Exhaust targets with our Overload Machine Guns. That said, there's no reason we shouldn't run this so that we have another possible way to Blind enemies when we're playing with a fireteam.
• Elemental Supercharger Elemental Supercharger will grant us Chaos Reach super energy when we defeat Exhausted or Severed enemies with Arc weapons. Again, this is a perk that will mostly rely on our fireteam applying Exhausted and Severed to targets, unless we can Exhaust targets with our Overload Machine Guns.
• Dreadful Finisher Dreadful Finisher isn't Arc focused, but it spawns Special ammo when we defeat powerful combatants with our finisher. This will especially help with Special ammo if we're running Coldheart.
