Fallen Sunstar

This build focuses heavily on spamming abilities and controlling the field. The exotic Fallen Sunstar increases your ability regeneration by picking up Ionic Traces. Ionic Traces are twice as strong with this exotic equipped, and regenerate x2 the amount of ability energy then normal. As an added bonus, allies nearby also regain ability regeneration when you collect Ionic Traces. The doubled increase in all ability regeneration allows this build to spam abilities as much as you want, without worrying about a cooldown.

One of the most important aspects is Arc Soul. This aspect will spawn a Arc Soul to fight with you when you cast your rift. The Arc Soul is capable of Jolting targets on its own, spawning Ionic Traces to help with ability regeneration. Allies that pass through your rift will also get an Arc Soul to help them. If you are amplified, your Arc Soul will be supercharged, which will gain increase fire rate. Electrostatic Mind is very important to the entire functionality of the build, as it will create Ionic Traces from all ability kills and Jolted enemy kills. You are also amplified after collecting an Ionic Trace.

Spark of Resistance increases your damage resistance to all incoming damage while surrounded by enemies. This makes surviving in the middle of fights much easier. Spark of Shock makes your grenade Jolt targets now, spawning Ionic Traces that provide ability regeneration. Spark of Ions will make more Ionic Traces by defeating any Jolted target. This is important as any regeneration to our abilities build into the amount of grenades/melee and rifts we can use. Spark of Magnitude increases the duration that your grenades last. This means our single grenade throw can Jolt even more targets that walk into it.

Class Breakdown

Weapon Recommendation
Exotic Weapon(s)

A very strong arc auto-rifle that plays into the arc subclass. This weapon regains ammo by sprinting, and when holding the trigger, will build up the intensity of the weapon. At max charge, it will cause explosions on targets and blind them. As an added bonus, by being amplified, you gain this charge automatically. This allows this weapon to be a very strong contender that makes using a primary slot exotic almost worth while.

Legendary Weapon(s)
Ikelos SMG

Ikelos is a very strong SMG that can roll with the Voltshot perk. Highly recommended in this build.


Forbearance is a great wave frame grenade launcher. Able to do great damage and good enemy control.

The Hothead

Hothead is one of the best rocket launchers in the game. One of the best weapons to use against just about any boss.

Perk Recommendation

Voltshot or Demolitionist

Any weapon with Voltshot is ideal for this build. Because Voltshot will jolt targets, creating more Ionic Traces and keeping our abilities charged. You could also get away with Demolitionist, it won’t synergize quite as well with this build, but it will help you keep your grenade energy charged.

Arc Siphon/Harmonic Siphon
Either one of these siphons works for the build. Recommend using the less expensive one that is currently available.
