By GigaGamer47 and 1 collaborators
Looking for five Vex builds that work great for different playstyles (subjective)? I’ve sunk silly hours into her and tested every tree. Here’s what’s strong now, why it works, and how to use it.

NOTE: I compiled all links here since Steam is removing my custom builds for skill points -> All 5 Vex Builds[drive.google.com]

Vex’s kit oversimplified: Your gun’s element sets your action skill and melee element; pick Incarnate for burst and reload loops, Dead Ringer for Specters/Reapers, or Phase Phamiliar for a tanky pet you can command.

Builds In This Guide:
  • Kinetic Incarnate (Witchy Trigger Finger): Eldritch Blast refills your mag and stacks gun damage while Vibe Check speeds the loop; plays best with big-hit kinetic or fast AR/SMG spray for boss and mob melt.

  • Specter Swarm Leveler (Dead Ringer): Drop stationary Specters on clean sightlines and let them beam while you stack gun/crit nodes; low gear needs, smooth early campaign, great hands-off clear.

  • Dark Pact Boss Melter (Dead Ringer): Pop Dark Pact to freeze clone decay and spike their attack speed; pair Wither for a damage amp and Coven for crit/regen; 3 Specters for statues, 2 Specters + 1 Reaper for rushers.

  • Cryo Ordnance Phamiliar (Trouble Tank): Chill and control lanes while Trouble soaks aggro; Icy Attunement refuels ammo/ordnance on kills and overshield windows keep you swinging safely.

  • Kill-Skill Gun Hurricane (Incarnate): Crits proc kill skills to snowball fire rate and damage; Witchy Trigger Finger keeps mags topped so you hold trigger through long boss phases without losing tempo.
Vex: The Siren Skills
Let’s start with the basics.

Vex’s trait, Phase Covenant, attunes her to the element of your current gun and converts action skill and melee damage to that element. That single rule makes matching elements matter, and it’s the thread that ties every good Vex build together.

Her three action skills are Incarnate for gun-centric burst with Eldritch Blast, Dead Ringer for Specter/Reaper clones that scale with your gun bonuses, and Phase Phamiliar if you want to run with Trouble, your spectral cat. If you’re deciding which direction to take, think about whether you want self-buffed gun DPS, stationary clone pressure, or a durable buddy soaking aggro.

5 Best Vex Builds (My Personal Favorites)
1. Kinetic Witchy Trigger Finger (Incarnate DPS)
If you like constant shooting with almost no reload downtime, this is the cleanest loop.

Run Incarnate with Witchy Trigger Finger and push the green tree’s gun and crit stackers. Eldritch Blast reloads your current gun and ramps damage, then Vibe Check accelerates your rotation so the skill is always back when you want it.

It shines with high base-damage kinetic weapons and rewards crisp crits. Add a Throwing Knife ordnance with the Penetrator augment when you find one to guarantee crits during boss windows.

Important: 49/49 Skill Points used. Tweak other skills as you see fit.

How I play it: keep Incarnate rolling, weave Eldritch Blast between shots, and ride lifesteal nodes while you stack crit damage. Jakobs shotguns and snipers feel absurd here, but fast ARs and SMGs work if you lean into fire-rate stacking.



2. Specter Swarm Leveler (Dead Ringer, early game comfort)
Leveling or playing undergeared? Dead Ringer with Specters is silly good because their damage scales with the same gun bonuses you’re stacking.

Open with Cold Iron and the early blue-green crit/gun picks, drop Specters on clean sightlines, then keep your own gun damage flowing while they beam targets for you.

Look for underbarrel launchers and cooldown-heavy Repkits to keep your rhythm snappy. This path is low gear stress and perfect for a first playthrough.

Important: 47/49 Skill Points used. Tweak other skills as you see fit.

Tips: place Specters on high ground so they don’t waste line of sight, and swap weapons to change your attunement before spawning them so they hit the right weakness. A Penetrator Throwing Knife plus Bloodletter turns shotgun crits into boss delete buttons even mid-campaign.



3. Dark Pact Boss Melter (Dead Ringer, Wither + Coven)
This is the “walk into the arena and watch the bar vanish” setup.

Use Dead Ringer with the Dark Pact capstone so your clones stop losing health and attack faster during the window. Pair Wither to debuff targets and Coven for crit chance and sustain. For stationary bosses, drop three Specters; for rushdown bosses, go two Specters and a Reaper to pull aggro.

Change elements via your equipped gun before each summon to always hit the weakness. It’s ruthless when executed cleanly.

Routing: spawn clones, pop Dark Pact, step back, and focus on gun crits to stack your kill skills while clones do the heavy lifting. Maliwan guns are great here because instant element swaps make pre-summon attunement trivial.



4. Cryo Ordnance Phamiliar “Trouble Tank” (Phase Phamiliar)
Want a buddy that soaks heat while you keep moving?

Run Phase Phamiliar with a Cryo lean. Icy Attunement restores ammo and ordnance on kills when attuned to Cryo, Overprotective and Blast Rites layer overshields, and the build converts a lot of your ordnance bonuses into Trouble’s damage.

It’s safer for new players, it freezes packs so they barely fight back, and it scales fine into story bosses.

Important: 49/49 Skill Points used. Tweak other skills as you see fit.

How it feels: command Trouble to jump in, freeze the pack, and play around your overshield windows for free damage and survivability. If you prefer kinetic crits over Cryo status, there’s a variant that swaps to Kinetic Phamiliar and pushes crit multipliers instead.



5. Kill-Skill Gun Hurricane (Incarnate, Mortal Terror core)
This one is for players who love stacking buffs mid-fight. You spec into the green tree’s Mortal Terror and Drink Full engines, add Target Prescience for crit access, and use Incarnate for uptime and the reload loop. You’ll maintain fire-rate stacks while proccing kill skills from crits alone, so even single-target boss phases never feel slow. If you want aggro relief, you can flex to Dead Ringer for Coven, but I keep Incarnate for maximum gun tempo.

Important: 41/49 Skill Points used. Tweak other skills as you see fit.

Weapons and kit: favor high-RPM Vladof SMGs/ARs with alt barrels for consistency, then grab Repkits that roll action-skill cooldown rate. It’s a simple feedback loop that hits like a truck once it’s spinning.
Optional Trainer Helpers (Use Responsibly)
  • Edit Skill Points (Stat Mods) - quick-swap between these five setups without grinding respec cash or levels. Handy if you bounce from Dark Pact bossing to Incarnate mobbing in one session.
  • Edit Money (Stat Mods) - buy key early guns and Repkits that make these builds click, like Maliwan element-swappers for clone setups or high-RPM Vladof pieces for the kill-skill hurricane.

so is vex's ability to have infinite ammo rocket launchers widespread knowledge? I accidentally found that and am now wondering if that's well known. Because that feels like at least an HM imo. Great list tho
