Aegis

At a Glance

Aegis is the yellow gear set that turned skill builds from "support only" into legitimate raid DPS. It rewards constant skill activity by spawning bonus projectiles from your deployed skills and stacking damage every time you press a skill button. If you have ever wanted your Pulse turret to feel like a second weapon, this is the set you have been waiting for.

The set sits in a hybrid niche: pure skill builds use it for raw DPS, support builds use it for off-DPS while running healing tools, and tank-skill hybrids use it because Bulwark on the chest gives you a free armor repair every time a skill kills something. It is one of the few yellow sets that actually scales with skill haste and skill damage simultaneously, which means you do not have to pick a lane.

Aegis is best in scenarios where you are deploying skills frequently — boss fights with adds, raid encounters with continuous waves, and Summit floors where you can keep a turret alive long enough to spawn the projectiles.

Set Bonuses Detail

2-piece bonus

The 2-piece grants +20% Skill Damage. Note this is plain Skill Damage, not Total Skill Damage, so it stacks additively with your gear rolls before being multiplied by the 3-piece. On a build with 200% Skill Damage from attributes, this becomes 220%, which is a meaningful 10% relative increase to the multiplier.

3-piece bonus

The 3-piece adds +25% Total Skill Damage. Total Skill Damage is the multiplicative outer layer — it is calculated after Skill Damage attributes are summed. This is what makes Aegis so strong on skills like Sniper Turret or Demolisher Firefly, where every multiplier counts.

Combined, the 2pc and 3pc give you roughly a 50% effective DPS uplift on skills before you even talk about the 4-piece, which is competitive with non-set chest-and-backpack combos.

4-piece "Shield of Many"

This is the headline mechanic. Whenever you have an active skill deployed, that skill periodically launches small homing projectiles at nearby enemies. The projectiles deal weapon-scaled damage modified by your Skill Damage stats. On top of that, each time you activate a skill (deploy or recall), you gain a stack of bonus damage to those projectiles, up to a maximum of 50 stacks.

Stacks decay slowly when you stop using skills, so the build wants you cycling skills constantly — deploy turret, recall turret, deploy hive, recall hive. Skill haste is therefore not a luxury, it is a core stat.

Chest talent: Bulwark

Bulwark repairs 25% of your armor whenever a skill kill is registered. This makes Aegis surprisingly survivable for a yellow set — your turret's projectiles, the 4pc projectiles, and any direct skill damage all count. In add-heavy content you can stay near full armor without ever shooting your gun.

Backpack talent: Reactor

Reactor increases the damage cap for the 4pc projectiles. Without it, projectile damage hits a soft cap quickly on stacked skill-damage builds. With it, your endgame ceiling is roughly 40% higher, which is the difference between Aegis being a B-tier set and the S-tier skill set it is today.

4pc Mechanic Deep Dive

The projectiles spawn on a fixed cadence — roughly every 1.5 seconds per active skill — but each individual deployed skill can spawn its own projectile stream. This means running two skills (turret + hive, for example) doubles your projectile output. Pulse-class skills, Reviver hive, and Demolisher Firefly all qualify, though Reviver hive only spawns projectiles while it has charges remaining.

Stacks are gained on skill activation, which the game defines as either deploying a fresh skill or recalling an active one. You do not need the skill to actually do damage to gain a stack. The fastest way to ramp is: deploy skill A, deploy skill B, recall skill A, recall skill B, repeat. With moderate skill haste you can hit 50 stacks in under 20 seconds.

Stacks persist for 8 seconds after your last skill activation, then decay one per second. In practice this means as long as you press a skill button at least once every 6-7 seconds you maintain full stacks indefinitely.

The projectiles count as skill damage for all purposes — they proc Bulwark, they benefit from amplified damage from teammates, and they are reduced by enemy armor as normal skill damage.

Best Skills

Aegis lives or dies by your skill choice. The strongest pairings are:

Sniper Turret + Pulse Turret — Sniper Turret gives you a high-damage primary while Pulse acts as a stack generator. The pulse also debuffs enemies for the projectile stream.

Striker Drone + Reviver Hive — Striker handles consistent ranged DPS, Reviver gives you team utility and stack generation. This is the standard raid build.

Demolisher Firefly + Restorer Hive — for solo content where you want burst skill damage on demand plus self-healing.

Striker Drone + Pulse Turret — pure DPS configuration, both skills contribute projectiles and stack generation.

Avoid Chem Launcher and Seeker Mine as primary skills with Aegis — they are activate-and-forget skills that do not stay deployed, so they spawn projectiles only briefly.

Top Builds

Aegis × Pulse Skill DPS

• 4 pieces Aegis (chest with Bulwark, backpack with Reactor)
• Backup gloves: Picaros Holster or Fox's Prayer mask
• Weapons: Capacitor (exotic AR for skill damage proc) or Scorpio
• Skills: Sniper Turret + Pulse Turret
• Stats: max Skill Damage, Skill Haste secondary, Weapon Damage tertiary

This is the standard endgame skill DPS build. Rotation: deploy both skills, fire Capacitor for 30 seconds of buff window, recall and redeploy to refresh stacks every 15 seconds.

Aegis × Reviver Hive (Raid Support)

• 4 pieces Aegis
• Specialization: Firewall or Technician
• Weapons: Eagle Bearer or Carbine 7
• Skills: Reviver Hive + Striker Drone
• Stats: balanced Skill Damage and Skill Haste

The raid utility build. You rez teammates with the hive, deal real damage with the drone and 4pc projectiles, and stay alive thanks to Bulwark repairs. In Iron Horse and Dark Hours this is one of the few builds that contributes both DPS and revives.

Aegis Solo Summit

• 4 pieces Aegis
• Backup: Coyote's Mask + Memento backpack
• Weapons: Scorpio (DTE on AR rolls) + Mantis
• Skills: Striker Drone + Restorer Hive
• Stats: Skill Damage primary, Armor secondary

Summit-floor build. Restorer keeps you alive, drone clears, projectiles handle the rest.

Pros and Cons

Pros

• One of the highest skill-damage ceilings in the game
• Strong group utility through Bulwark sustain
• Works in solo, group, and raid content
• Two yellow talents (Bulwark, Reactor) on the same build
• Fast stack ramp with skill haste

Cons

• Useless if your skills are destroyed or on cooldown
• Demands skill haste investment, which competes with skill damage rolls
• Projectile targeting is enemy-AI dependent, so wide-open arenas perform worse than tight chokepoints
• 4pc is bottlenecked without Reactor backpack — without it, Aegis is mediocre
• Struggles against high-armor bosses where projectile chip damage scales poorly

FAQ

Q: Do the 4pc projectiles benefit from group buffs like Future Initiative or Tag Team? Yes. They count as skill damage, so any group buff that affects skill damage applies. This makes Aegis amazing alongside a Future Initiative healer.

Q: Can I run Aegis with only 3 pieces and use a different chest or backpack? You can, but you lose access to Reactor (which roughly doubles your endgame projectile damage) and you give up the 4pc bonus. The 3pc-only Aegis is not worth running over a brand-set skill build.

Q: Does the projectile damage scale with weapon damage attributes? No. It scales with Skill Damage, Total Skill Damage, and the Reactor backpack cap. Weapon damage rolls are wasted on a pure Aegis build.

Q: How do Bulwark and Refurbish stack? Bulwark is on the Aegis chest. Refurbish is the Foundry Bulwark backpack. They do not interact directly, but you cannot run both since each occupies a different slot configuration. If you want sustain, just use Bulwark.

Q: Is Aegis better than Striker for skill builds? Striker is for weapon DPS. Aegis is for skill DPS. They are not competing — they are different archetypes. If your build's damage comes from your skills, Aegis wins easily.

Q: Does the 4pc work during the descent? Yes, in any mode where gear sets are active. The Descent has its own loot pool but standard gear sets function normally outside of it.

Q: How do I gear-check an Aegis build? Three things: Skill Damage above 200%, Skill Haste above 100%, and Reactor backpack equipped. If any of those are missing the build underperforms by 30% or more.

Q: Best specialization? Firewall for the skill damage bonus and the flame turret as a third skill source. Technician is second-best for the artillery turret.

Closing

Aegis is what skill builds always wanted: a set that rewards active play instead of passive turret-sitting. The constant cycle of deploy-recall-restack keeps the gameplay engaging, and the projectile mechanic gives you something to watch for during fights. Pair it with the right backpack (Reactor, always Reactor), invest in skill haste, and you have a build that competes with weapon DPS in nearly every encounter.

For new players, Aegis is reachable without raid drops — every piece can target-loot from Manning National Zoo. For veterans, it is the answer to "what do I run after I have farmed Striker?"
