Introduction

My daily driver [Volt Prime], built around the 32.0 buffs to his 2 and 3. This is a very fast, reasonably tanky build for general content. Many would rather drop Shock before Discharge when adding Helminth abilities, but we're dumping range and efficiency. His 1 also has niche utility if you're willing to cut a mod (probably Constitution, with the relevant forma) for Shock Trooper.

How to Play

Press 3 --> Pick up the shield --> Press 2, refresh when either goes away. Congrats, you're now [Garuda], except you like guns more than melee.
Press 4 whenever there's more than, like, three enemies on your radar.

In practice, the build plays like [Nezha], but trades raw damage and tanking for speed and armor stripping. It's a lot comfier for easy content, but requires much more micromanagement against high level SP. I wouldn't bring it to endurance.

Notes about the Build

• We are dipping into negative efficiency because carrying a shield no longer costs energy, which removes all of Volt's energy issues when playing run-and-gun. Your two main skills will have ~30s/60s uptime respectively, and cost a total of 94 energy to use. You should have no problem keeping both active at all times even with just a Rank 0 Arcane Energize. I know, because that's all I have. Add Zenurik if you're that desperate, or cut Blind Rage for anything else. More on that below.
• I subsume Pillage for late game scaling. You can try other, funnier STR/DUR abilities like [Xata]'s Whisper, [Firewalker], Roar, [Mirage], Terrify, Infested Mobility, Silence, etc., as you like, but I think the overall utility here is hard to beat. Notably, Dispensary is a waste of time, even Max Rank. As mentioned, Volt's current energy economy is exceptional.
• Adaptation is non-negotiable given that our survivability is coming from Pillage overshields. I guess you could try swapping this to [Rolling Guard] and hope that your riot shield keeps you safe, but enemies will often spawn behind you and one shot you, especially when you get to SP.
• We are running [Corrosive Projection], Molt Augmented, and 282% Strength so we can get full armor stripping with a single cast of Pillage. You can cut Power Drift for another exilus/less forma and still get the max strip, but I like the extra lenience it gives you. Obvious alternatives are Primed Sure Footed, Rush, or Vigilante Pursuit.
• You can obviously lower the strength and/or change the arcane if you go for a different Helminth ability; alternatively, you can cut Blind Range to lower strength to 165% for two casts of pillage to do the same thing for about the same energy cost.
• I don't think there are many other useful Auras. I guess [Brief Respite] with a Decaying Dragon Key and Rolling Guard could do some shieldgating stuff, but then you start running into energy issues.
• I haven't bothered with shards yet, but the generally good ones like more strength and reduced casting time seem decent. YMMV.
• [Archon Stretch] is cute, but it doesn't make sense here. Energy economy isn't an issue, Shock is basically flavor text, and range is our dump stat. It's honestly the least interesting buff to [Volt], in my opinion.

Recommended Weapons

Obvious meta picks aside, you can run anything that benefits from high attack speed and doesn't have intense ammo issues.

In terms of primaries, I prefer bullet hoses with a lot of punch through; the changes to AoE make room-clearers kind of annoying when you factor in how quickly Volt can chew through magazines. I'll shout-out the [Quellor] as a fun, janky option that I personally use a lot. It gets a ton of use out of all of Volt's buffs, and can hit surprisingly hard when modded properly -- even before accounting for its awesome Riven dispo.

Secondaries are a mixed bag. The obvious winners are already-broken weapons like the [Laetum], [Kuva Nukor], and [Tenet Cycron], but a lot of powerful niche weapons get better, too. The [Knell Prime] benefits greatly from increased reload and attack speed, and allows for an alternate playstyle where you set up a shield in a safe corner and just camp. I also like the Aegrit when I run a bullet hose primary -- while it has no direct synergies with [Volt], it lets you get away with the fun stuff I mentioned in the paragraph above.

Finally, I'd really only recommend melee weapons that have some form of ranged attack, i.e. a Xoris, Glaive Prime, Stropha, or Redeemer Prime. Riot Shield Volt hates melee-range combat, as a lot of his survivability comes from his mobile shield. The massive buff to attack speed also turns these weapons into close-range combo monsters - I can regularly hit millions of damage with only moderate amounts of combo build-up, even on dedicated heavy attack builds.

Conclusion

Hope you enjoyed this guide! [Volt] is pretty strong right now, and more importantly, he feels great to play. My only complaint is that his 3 should have a hold-cast option to directly deploy a mobile shield... that said, DE and QoL aren't exactly things I'd associate together. Leave any feedback you have -- I'm relatively new to making and posting my own builds, and I would appreciate and input you have!
