Mobalytics API Will Be Updated Soon

Ionic Sentries are the latest addition to the Stormcaller’s arsenal, and today, we’re going to break down the best way to build around this powerful new ability.

That means we’ll be looking at the best Exotics, weapons, artifact mods, and class tree options that will help you get the most out of Ionic Sentry.

How Ionic Sentry Works This new Aspect gives Stormcallers access to a stationary Arc turret, which is activated using a secondary grenade charge. However, don’t mistake this for Arc Souls—that’s a completely different ability, and we can actually integrate both into this build for even more firepower.

The way Ionic Sentry works is similar to Gunpowder Gamble for Hunters. As you defeat enemies with Arc weapons, Arc abilities, or kinetic weapons, you’ll build up Ionic Sentry stacks. Once fully charged, your grenade ability temporarily changes, giving you the option to throw an Ionic Sentry instead.

After deployment, the Ionic Sentry:

Blinds nearby enemies for about 7–8 seconds, taking them out of combat. Targets nearby enemies and continuously hits them with Arc energy, dealing one tick of damage per second at around 200 base damage per tick. This significantly improves Stormcaller’s crowd control abilities, making it far more effective at handling large groups of enemies and even Champions, particularly Overload and Unstoppable Champions.

Each time the Sentry lands a hit, you’ll gain a Bolt Charge stack—a brand-new ability introduced in Destiny 2 that works similarly to Solar Ignitions.

What Are Bolt Charges? Bolt Charges function like giant lightning strikes, dealing heavy localized damage. Their power level is comparable to Ignitions, but rather than spreading fire, they release a focused Arc blast.

To build up Bolt Charge stacks, you’ll need an Aspect, Fragment, or Artifact mod that grants them. Defeating enemies with Arc weapons or Arc abilities will add stacks, and once you reach 10 stacks, you can unleash a Bolt Charge explosion using your grenade, melee, or Super.

Bolt Charges can also be triggered passively by:

Arc Souls Ionic Sentries Weapon perks like Chain Reaction, Firefly, Voltshot, and Jolting Feedback With two major new abilities added to Stormcaller, along with several powerful artifact mods, the subclass is now stronger than ever.

Best Exotic for an Ionic Sentry Build There are several Exotics that pair well with Ionic Sentry, including:

Geomag Stabilizers – Enhances Super uptime. Crown of Tempests – Improves Arc ability recharge. Getaway Artist – Converts your grenade into a powered Arc Soul (great for Prismatic builds). However, the best Exotic choice for an Ionic Sentry Stormcaller build is the Vesper of Radius chest piece.

Why Vesper of Radius? This Exotic comes with the Planetary Torrent intrinsic perk, which offers several advantages:

When surrounded by enemies, your class ability regenerates faster. Starts at 250% regen increase with three nearby enemies. Maxes out at 1500% regen increase with six enemies nearby. When activating your Rift, it releases a shockwave that: Deals 400 base damage to enemies. Blinds all nearby enemies, rendering them defenseless. After the initial wave, additional shockwaves trigger every 5 seconds, meaning each Rift can release three total bursts of damage. Enemies defeated by these shockwaves explode, dealing 200 base damage and blinding more enemies. By combining Ionic Sentry and Vesper of Radius, we’re essentially removing enemies from combat in multiple ways—our Rift blinds them, our Ionic Sentry blinds them, and we’re constantly pumping out Arc damage.

Since blinded enemies can’t fight back, this makes up for the fact that Stormcaller lacks the healing potential of Solar or Void subclasses. Instead of out-healing damage, we’re completely shutting down enemy aggression.

Class Tree Setup: Aspects, Abilities, and Fragments For this build, we’re running double turrets—Ionic Sentry and Arc Souls—to maximize our automated damage output.

Aspects: Ionic Sentry – Grants access to the Arc turret. Arc Soul – Grants a floating Arc turret when using a Rift. Some may worry about not using Electrostatic Mind, since it generates Ionic Traces when defeating Jolted or Blinded enemies and provides the Amplified buff. However, we don’t actually need this Aspect to become Amplified—all we need to do is rapidly defeat enemies with Arc abilities and Arc weapons.

Additionally, the Flashover artifact mod will automatically Amplify us when we reach 10 Bolt Charge stacks. If necessary, we can also use Ex Diris, which grants Amplified on final blows and works well in this build.

Fragments: Spark of Ions – Generates Ionic Traces when defeating Jolted enemies or enemies killed by Bolt Charges. Ionic Traces restore grenade, melee, and class ability energy. Spark of Amplitude – Creates Orbs of Power when rapidly defeating enemies. This helps maintain Super energy and activates Weapon Surge mods. Spark of Instinct – When critically wounded, releases an Arc burst that Jolts nearby enemies. Combos well with Vesper of Radius for additional AoE crowd control. Spark of Resistance – Provides 15% damage resistance when surrounded by enemies. Stacks with Amplified’s 15% damage reduction, improving survivability. Since Orbs of Power are crucial for survivability, we’re using Recuperation (Boots Mod) to restore 70 HP per orb pickup.

Artifact Mods: We prioritize Arc-based mods for Bolt Charge synergy:

Dielectric Mod – Increases Bolt Charge gain from Jolt and Blind kills. Flashover – Bolt Charges deal 150% more damage and auto-Amplify at 10 stacks. Defibrillating Blast – Stunning Champions grants a full Bolt Charge, Jolt effects, and restores 55 HP. Hold the Line – Provides health restoration when using Machine Guns. Particle Reconstruction – Fusion Rifles gain auto-reload and bonus damage when dealing sustained damage. Weapon Recommendations: Exotics:

No Time to Explain – Adds a third automated turret with its time portal. Riskrunner – Provides an Arc overshield and chains lightning between enemies. Anarchy – Synergizes well with Ionic Sentry and Rift shockwaves for passive Arc damage. Centrifuse / Trinity Ghoul – Excellent Arc crowd-control options. Legendary Weapons:

Indebted Kindness (Sidearm) – Barrier piercing + Volshot for Overload stuns. Psychopomp (Grenade Launcher) – Rolling Storm perk helps build Bolt Charges faster. Vantage Point – Voltshot weapon with strong Arc synergy. VS Pyroelectric – Jolting Feedback and Voltshot make it a great fit. Conclusion With Ionic Sentry, Vesper of Radius, and powerful Arc artifact mods, Stormcaller has never been stronger in endgame PvE content. This build controls the battlefield through constant blinds, automated damage, and Bolt Charge explosions, making it one of the best ways to play Arc Warlock right now.
