Ionic Turret's potential may be getting criminally underestimated here
I was like everyone else on this forum a day ago thinking that the new Stormcaller aspect was dead on arrival. But once you look into the available fragments and exotics to pair with it, it's becoming increasingly clear to me that we may have a new version of Bleak Watcher on our hands.
Let's start with fragments. We already know that Gunpowder Gamble works with fragments that affect your grenade (Ember of Resolve, Facet of Mending). As a result, I'm almost 99% sure the aspect will work with Spark of Shock with it being an Arc grenade for all intents and purposes. This means it will be applying jolt to just as many ads as Bleak Watcher applies slow/freeze. This will be incredibly strong for ad clear, to the point where I can see why the turret is dealing so little damage. Imagine if the Bleak Watcher did large amounts of damage on top of its status effects, that wouldn't be balanced!
The other fragment to keep an eye on is Spark of Amplitude, since this aspect is technically a lingering Arc grenade. I foresee this being a similar situation to Whisper of Durance with Bleak Watcher, where it gains an additional 5 seconds of duration. This could allow you to have two turrets up at the same time, depending on how long the aspect's cooldown is.
And here's why this aspect is actually better than Bleak Watcher: it doesn't actually eat your grenade charge, instead relying on kills. So those previous two fragments? Congratulations, they also apply to one of the best grenades in the game - Pulse Grenades.
Let's take it up to 11 now - Verity's Brow is about to be absolute meta. We already know that with Bolt Charge you should be using your weapons to get your stacks up quickly, so why not benefit from Arc weapon kills? At max stacks, we're talking 250% regen rate on your pulse grenades, and 100% increased damage on both your pulse grenades AND the Ionic Sentry. I can confidently say this because Spirit of Verity already works this way with Gunpowder Gamble, and Verity's damage bonus works with Bleak Watcher. This should make up for the damage being lackluster according to some people here. On top of those insane benefits, every time you throw out your Ionic Sentry or Pulse Grenade, your allies will get 10x grenade recharge rate. Depending on how often you can throw out another Ionic Turret, this may just be one of the best DPS strategies in the game. Now, it's entirely possible Bungie might exclude the Ionic Sentry from activating Feel the Flames, but that doesn't negate the rest of the exotic's synergies with this aspect.
The other aspect I'd run is probably Electrostatic Mind, since Ionic Traces will give us even more Bolt Charge with the right fragments as well as more Pulse Grenade energy. The final two fragments I'd recommend are:
Discharge - Arc weapon final blows have a chance to create an Ionic Trace. Picking up an Ionic Trace grants a stack of Bolt Charge.
Frequency - Melee hits increase your equipped weapon's reload speed and stability for a short duration. While Amplified, gain a bonus stack of Bolt Charge from all sources.
The reload speed and stability will be awesome for getting more fuel for Verity's, and we'll get even more Ionic Traces for doing so. Your Bolt Charge will also be going up like crazy, since the turret will also be granting it on kills (which should be easier to do with 100% increased damage and jolt).
I dunno, maybe I'm reading into all of this, but I think this aspect has a good shot at making Stormcaller meta for the first time in forever.
