Falling Star Arc Titan Build

Heresy

Last Updated:February 9, 2025|Changelog

The Cuirass of the Falling Star Arc Titan has been a consistently strong choice since its release. It got stronger with Plunder's Arc 3.0 update, and once more during the Final Shape. Now, Strikers have access to Storm's Keep, opening up a chance for Falling Star to have a more meaningful and well rounded role on the battlefield. This build massively boosts your Fireteam's damage, keeps them alive, lets you generate your Super extremely quickly, and allows that Super to deal devastating damage itself.

Cuirass of the Falling Star massively increases the damage of your Thundercrash and allows you to generate it faster when you score Melee Ability Kills. You also gain a potent Overshield when you do this. Ballistic Slam is used as it also inherently generates Super energy for every enemy it hits, look for a good chance to use it and be rewarded with a massive chunk of your Super. Because you reliably have your Super which provides invaluable burst damage, the rest of the build is dedicated towards helping your team do damage and clear out enemies.

Between Edge of Action and Adamantite, you provide your allies with a potent Weapon damage buff that stacks with EVERYTHING, healing, and an easy access to full Void Overshields. This is all on top of the centerpiece of Support: a Storm's Keep enhanced Rally Barricade grants all allies near it rapid Bolt Charge generation and the ability to Discharge it with Weapon damage.

This build is rounded out by the Arc Machine Gun you carry, and the Touch of Thunder enhanced Pulse Grenade which enables great Ability uptime.

WARNING: You must own the Beyond Light Pack to unlock Cuirass of the Falling Star

Pros

Big super damage
Phenomenal Support
Machine Gun based Ad-Clear

Cons

Poor sustained DPS
Poor individual damage output without Super

Gameplay Loop

This build doesn't revolve around a loop as much as it has objectives to fulfill.

If you see a group of weaker enemies, go out of your way to Ballistic Slam them. This gives you massive amounts of Super energy.
Throw your Pulse Grenade at tough targets to maximize Ionic Trace generation. If you need Ads to die quickly, use your Machine Gun - otherwise, use your other weapons to ready Healing rounds and Remote Shield. If you're able to use your Glaive a lot, place Remote Shields in key areas to support your Fireteam. They are bound to get good use out of its Void Overshields.
If an ally is in trouble, heal them. If you're in trouble, use the Glaive's frontal-shield or Remote Shield to survive.
When it comes time for the Fireteam to deal Boss dps, place your Remote Shield and Rally Barricade in advance, then heal allies with Adamantite. This combo dispenses all of your Supporting tools, finally leaving you with your enhanced Thundercrash to use against the Boss. Return to your team to deal what damage you can, Heal allies as needed, and place Rally Barricades as often as you get them.

Ability Breakdown

Super

Thundercrash
- Hurtle through the air like a missile and crash into targets to inflict meteoric damage. On it's own this is a mediocre super, but pairing it with Cuirass of the Falling Star makes it devastating.

Abilities

Rally Barricade, the best pairing for our Aspect dispensing invaluable Support, this Barricade also taunts enemies, provides allies with improved resistance against splash damage, and improves Weapon-feel.
Strafe Lift, Jump of your choice!
Ballistic Slam, Run and soar through the air to be able to use this Melee Ability, causing you to plummet downwards and slam the ground, dealing damage in a large area that scales with distance. Every enemy hit by this gives you Bolt Charge and a chunk of Super energy. Thanks to our Exotic armor, you get even MORE Super Energy for every enemy killed by this Ability.
Pulse Grenade, This Grenade Ability feeds into your other Abilities thanks to your other Aspect, causing it to rapidly generate Ionic Traces as it damages enemies over time. You want to throw this at tougher enemies to get the most out of it!

Aspects

Touch of Thunder, This enhances your Pulse Grenade, allowing it to partially recharge your other Abilities and itself. More Melees means more Super, and more Barricades means more Support.
Storm's Keep, placing your Rally Barricade down grants 4 stacks of Bolt Charge to yourself and nearby Allies. All allies behind the Barricade rapidly receive more stacks of Bolt Charge and have the ability to Discharge Bolt Charge through Weapon damage instead of just Ability damage. This allows your Barricade to contribute a lot of damage over the course of a Boss damage phase, making it invaluable for Support.

Fragments

Spark of Magnitude, Your Pulse Grenade lasts slightly longer, letting it deal more damage and generate more Ionic Traces.
Spark of Recharge, You gain massively increased Melee and Grenade Ability generation when near death.
Spark of Discharge, Your Arc Machine Gun gains the ability to generate Ionic Traces, and collecting Ionic Traces gives you more Bolt Charge.
Spark of Resistance, Never say no to more survivability. This stacks on top of Amplified's 15% damage resistance and enemy accuracy reduction.

Kinetic Weapon: Adamantite - A Healing Auto Rifle capable of further Support through Slice and Attrition Orbs. The second perk synergizes with the Artifact, allowing this Weapon to function as an Anti-Barrier tool. This gun drops from Episode Heresy's activities.
Energy Weapon: Edge of Action - The Titan-exclusive Exotic Glaive includes Destabilizing Rounds and its unique Remote Shield, creating a miniature Ward of Dawn that grants numerous Buffs to allies that walk inside it. Unlock this through completing all of the quests on the Investigation Board in the Enclave on Mars (if you've already unlocked another Class-Glaive, you unlock this Weapon's Pattern through Master Wellspring instead). This requires ownership of The Witch Queen DLC. See the Variants tab for alternative Support Weapons.
Power Weapon: Watchful Eye - One of many viable Arc Machine Guns, this one features the extremely convenient Overflow and speedy Ad-clear through Rolling Storm. This Weapon drops from Episode Heresy's activities, though any other Arc Machine Gun works if you can't get this one.

Variants

Alternative Weapons

The goal of this build's Weapons are to Support allies as much as possible while still leaving yourself some room to be able to Ad-clear yourself.

There's more ways to do this than what was recommended, consider any of the following Weapons to mix and match as you desire:

Primary Ammo Weapons

Lumina, Weapons with Heal Clip, Support Frame Auto Rifles, Alethonym, and Red Death Reformed.

Special Ammo Weapons

Divinity, The Navigator, Vexcalibur, Ergo Sum with Wolfpack Rounds, and Grenade Launchers with Disorienting Grenades.

Power Ammo Weapons

Tractor Cannon,D.A.R.C.I., and Gjallarhorn.

Summary

Cuirass of the Falling Star Thundercrash Titan has always been a great option for Boss damage and as forgotten for the longest time. The introduction of Storm's Keep allows this classic build to fulfill a new role: Support. Even as you dedicate much of the build towards support, the Exotic still allows you to deal respectable Boss damage. This versatility is something very uncommon for the sandbox. Wherever you take this build, your allies are sure to greatly appreciate your presence while your enemies are bound to fear you just as much.
