Ashley Build

This build is extremely strong. Thanks to the skills and gear we pick she will be able to take down the strongest enemies in-game single-handedly. This can be expected as she is a Spectre-level soldier like Shepard.

Order Skill Description
1 marksman mass effect 3Marksman Lv 3 This is the main ability that Ashley will use throughout the game. It improves her fire rate allowing her to shred enemies apart. Unfortunately, she does not get any benefits from accuracy.
2 concussive shot mass effect 3Concussive Shot Lv 3 A useful ability that deals bonus damage against enemy barriers.
3 inferno grenade mass effect 3Inferno Grenade Lv 1 We take a single level as the ability can be useful against heavily armored enemies in the mid-game when you get Ashley.
4 disruptor ammo mass effect 3Disruptor Ammo Lv 3 This is a very powerful skill that increases damage against shields, enemy health, overheats enemies' weapons, and shreds synthetic enemies. A very versatile ability for Ashley
5 alliance officer icon mass effect 3Alliance Officer Lv 6 The goal is to maximize this ability once you have base skills ready. It provides extremely high bonuses to weapon damage, especially Assault Rifles. Take Weapon Damage, Power Damage, and Assault Rifles upgrades. Ashley shines when she is on offense
6 marksman mass effect 3Marksman Lv 6 Take the Firing Rate, Duration, and any of the 6th upgrades. I personally prefer Recharge Speed, so that the abilities could be used faster in case there is a need. For maximum offense take Accuracy & Firing Rate upgrade
7 disruptor ammo mass effect 3Disruptor Ammo Lv 6 Take Damage, Headshots, and Damage upgrades. Stun is also a good choice, but my personal preferences are upgrades that are always active.
8 concussive shot mass effect 3Concussive Shot Lv 6 Now we put the finishing touches for this ability, which should have come in handy throughout the game. Take either upgrade at the 4th level. After that take Recharge Speed and Amplification. The last upgrade will greatly improve the ability thanks to Disruptor Ammo.
8 inferno grenade mass effect 3Inferno Grenade Lv 3 To finish of the build we put the rest of the points into grenade ability. At this point in the game, this will small impact on the build as Ashley should be tearing enemies apart easily.

Tactics and Squad

Generally speaking, once you obtain N7 Typhoon and fully upgrade Alliance Officer skill for Ashley she becomes unstoppable. However, here are my general suggestions for her, especially early in the game:

  • Concussive Shot - this is a very powerful ability that deals 400% damage to barriers. This allows Ashley to be effective against two protections - barriers and shields (thanks to Disruptor Ammo). it can also detonate Fire, Cryo, and Tech explosions.
  • Actively control Ashley - you should put the effort into commanding her positions over the battlefield. She is the most effective when in mid-range with her Assault Rifle. Due to this use squad commands to position her with a good view.
  • Use piercing mods on weapons to allow Ashley to shoot through walls, as she may miss often the enemy's chest.


As the build is purely offensive Ashley can be used in any combination. However, here are some companion tips for maximum effectiveness:

  • James Vega - has impressive ability - Incendiary ammo. You can use Concussive Shot to detonate Fire Explosions once the enemies are set on fire.
  • EDI and Garrus - both have tech ability Overload. It can be detonated with Concussive Shot. Moreover, Ashley has Disruptor Ammo squad ability. It enhances her normal shots against barriers and shields. Moreover, it primes Tech Bursts, which mentioned companions can then utilize with Overload. So it is a two-way synergy.

Unfortunately, Ashley cannot do much to help detonate Biotic Explosions, and for that, you should use a combo of unrelated characters:

  • Liara, Kaidan, or Javik with Adept or Sentinel - in this case, Ashley would play a role in tearing up enemy Shields as these characters might have difficulties against this protection

But overall Ashley can be part of anything after you get the recommended gear.


This section will cover what equipment you should be using with Ashley Build. She can use two types of weapons Assault and Sniper rifles

Assault Rifles

Name Upgrades Description
N7 typhoon mass effect 3N7 Typhoon Magazine
Extend Barrel
This is a crazy weapon, that can pierce through covers. It will allow Ashley to tear enemies in a few shots.
m7 lancer mass effect 3M-7 Lancer Piercing Mod
Extend Barrel
A more balanced weapon option. This will make Ashley a bit more realistic in terms of damage compared to the N7 Typhoon
M-76 revenant mass effect 3M-76 Revenant Piercing Mod
Extend Barrel
Another great option. It has a very high fire rate and a large magazine.

Sniper Rifles

Name Upgrades Description
black widow mass effect 3Black Widow Magazine

This weapon has innate 25 cm cover penetration. So it is effective against shielded enemies. Moreover, it has 3 ammo clips.
Krysae sniper rifle mass effect 3Krysae Sniper Rifle Piercing Mod

Deals explosive damage. It is very effective against multiple enemies.


In mass Effect 3 different companion armors provide some different stat boosts. So it is a good idea to see what you pick. Here is what I recommend for the Ashley build:
