Mass Effect 2 Legendary Edition

Best Sentinel Builds

Matt Chard

This page will show you some of the best Sentinel builds in Mass Effect 2. Here, you’ll find details on the best abilities to pick, the best weapons to equip, including what heavy weapon to choose. Also, you’ll find what armor works best for the build.

Sentinel Overview

The Sentinel, like the Soldier and Engineer, is a core class in Mass Effect 2. The Sentinel shines at being able to deal with all forms of protection the enemies may have due to them having access to both Warp and Overload. Also, they have great survivability thanks to Tech Armor that boosts your shields.

Assault Armor Build

This build revolves around your Tech and Biotic Powers whilst keeping your survivability up from Tech Armor.

Power Evolution Squad Points
Overload Heavy Overload 10
Warp Heavy Warp 10
Tech Armor Assault Armor 10
Defender Guardian 10
Bonus Power: Reave Heavy Reave 10


This section will go into more detail on why the Powers are chosen for this particular build.


Overload is the de facto Power to use when you want to strip the enemies of their shields. We choose the Heavy Overload Evolved variant as this increases the damage to Overload allowing you to do take the enemies shields down even quicker.


Warp is great to use against enemies that have Barriers or Armor, and on top of that, it can stop health regeneration as well. We choose the Heavy Warp Evolved variant as this increases the damage to Warp allowing you to do increased damage to Armor.

Tech Armor

Tech Armor is a unique Tech power exclusive to Sentinels. At max rank, it’ll increase your shields up to 100% of your base shield value, although it doesn’t take account of your armor increasing your shield strength, Assault Armor will replenish 50% of them when your shield is destroyed which is the reason we went with this variant of the Power. Furthermore, Tech Armor doesn’t need to be reapplied, just put it on at the beginning of a Mission, and it’ll stay on indefinitely until it gets destroyed. It’s worth noting that the other variant is arguably better for this build as it takes away the second shield Assault gives you, but it’ll increase your Biotic Damage by 15% and your shield strength to 100%.


We max out Defender to get all those Health and Cooldown passives allowing you to take more hits, and cast more powers. We choose the Guardian variant for the better Power recharge, and slightly increased health.

Bonus Power

Bonus Powers are granted to you when you complete a companions’ loyalty mission, once you have the Power unlocked, head to Mordins tech lab on Deck 2 of the Normandy, and learn it from the Advanced Training Research Upgrade. You can only have one of these Powers equipped at any given time. We chose the Reave Power from Samara because it’s, in general, a great power. This will double the damage to armor and barriers, and it will restore some health if it’s used against organic enemies, as well as giving you bonus health on top.


This section will talk about what weapons are best for this particular build.

Heavy Pistol

Weapon Base Damage Accuracy Recoil Fire Mode Fire Rate Clip Size
M-5 Phalanx 109 High High Semi-Automatic 80 RPM 6

The M-5 Phalanx was originally added as DLC in the original Mass Effect 2, in the Legendary Edition, it can be purchased from Ratch, who resides on Tuchanka.

What makes the M-5 Phalanx so effective, is that it’s highly accurate due to its built in laser, and it hits like a truck with 109 base damage. Like most handguns, it’s better to use against enemies with armor, or as a weapon to fall back on if you run out of ammo in your primary or the enemies close the gap, making it harder to snipe them.

Submachine Gun

Weapon Base Damage Accuracy Recoil Fire Mode Fire Rate Clip Size
M-12 Locust 25 High Low Automatic 550 RPM 20

The M-12 Locust was originally added with the Kasumi - Stolen Memory DLC which is Kasumi’s loyalty mission, in the legendary edition, the mission is available once you acquire Kasumi at the Citadel. The weapon can be picked up during the mission, or if you miss it, as a mission reward.

The Locust is one of the strongest SMG in the game, especially at mid to long range due to its pinpoint accuracy, and low recoil. This makes it act more like an Assault Rifle than a SMG.

Advanced Weapon Training

During the Mission Collector Ship, you’ll get the choice to get Advanced Weapon Training, this will allow you to pick another weapon type to add to your arsenal, that your class wouldn’t normally be allowed to use.

For this build, choose Sniper Rifle. This will reward you with the M-98 Widow, the best Sniper Rifle in the game.

Best Heavy Weapon

Weapon Base Damage Accuracy Recoil Fire Mode Fire Rate Clip Size
M-100 Grenade Launcher 500 High Low Semi-Automatic 125 RPM N/A

The M-100 Grenade Launcher is the first Heavy Weapon you’ll get in the game, you’ll get it during the Mission Prologue: Awakening. The reasoning behind choosing this, is its crowd control capabilities which as a Sentinel using this build, you won’t have much of.

Best Armor

Armor Location Cost Stats
Blood Dragon Armor Kenn’s Salvage, Omega Market 50,000 (less with discount) 15% Power Damage Bonus, 10% Shield Strength bonus

Best Squadmates

Because the Sentinel can deal with all the protection stripping on the enemies, and they have great survivability, the only thing you really need to supplement that is more DPS. With that in mind, take Garrus equipped with a Sniper, and Grunt to push enemies away from cover, he’s also great if you’re getting swarmed by husks. Miranda is always a good shout as she can handle anything, but she’s more useful if you need someone to strip the enemies’ protection, which is what you’ll be doing.
