    Hey everyone! Vazgen here with the next installment of the Power Guide - series of articles called to shed light on different powers from Mass Effect trilogy. Today we focus on...

    Concussive Shot

    This power is first introduced in Mass Effect 2 but truly shines in Mass Effect 3.

    Mass Effect 2

    Concussive Shot is a Soldier-exclusive power and only Garrus, Zaeed and Grunt have access to it besides Shepard. The power ranks are as follows:

    Rank 1
    Recharge Time: 6.00 seconds (Shepard); 12.00 seconds (others)
    Force: 250.00 newtons
    Damage: 45.00 points

    Rank 2
    Recharge Time: 6.00 seconds (Shepard); 12.00 seconds (others)
    Force: 350.00 newtons
    Damage: 60.00 points

    Rank 3
    Recharge Time: 6.00 seconds (Shepard); 12.00 seconds (others)
    Force: 450.00 newtons
    Damage: 75.00 points

    Rank 4
    Heavy Concussive Shot / Concussive Blast
    Recharge Time: 6.00 seconds (Shepard); 12.00 seconds (others)
    Force: 600.00 / 450.00 newtons
    Damage: 100.00 / 75.00 points
                                 / Impact Radius: 3.00 meters

    In ME2, Concussive Shot fires a projectile that tracks moving targets but does not arc behind cover. The projectile is not visible for squadmates. If the enemy is behind cover, squadmate Concussive Shot will hit cover instead.

    Loading screen tip mentions Concussive Shot being effective against Barriers. While it is somewhat true, even Heavy CS can't drop the barriers of the weakest enemy on Insanity. Here you can see the video showcasing the damage it does at all difficulties: Link

    Like any knockdown or lifting power it instantly kills unprotected husks. Concussive Shot also has the properties of Throw for the purposes of physics combos on lifted targets (though not as effective due to lower force). Concussive Shot is also a combat power which means that it is not affected by tech and biotic cooldown bonuses.

    Mass Effect 3

    In Mass Effect 3 Concussive Shot is also Soldier-exclusive and available to Garrus and Ashley from squadmates (Grunt and Zaeed in Citadel DLC). In multiplayer, it is available to the Human and Turian soldier. The power ranks are as follows:

    Rank 1: Concussive Shot
    Flatten your enemy with a precise blast at short or long range.

    Recharge Speed: 5 sec
    Damage: 100 (200 multiplayer)
    Force: 300 N

    Rank 2: Recharge Speed
    Increases recharge speed by 25%.

    Recharge Speed: 4 sec

    Rank 3: Force & Damage
    Increase force and damage by 20%.

    Damage: 120 (240 multiplayer)
    Force: 360 N

    Rank 4: Force & Damage / Radius
    Increase force and damage by 30%. / Increase impact radius by 1.50 meters.

    Damage: 150 (300 multiplayer) / 120 (240 multiplayer)
    Force: 450 N / 360 N
                           / Radius: 1.50 meters

    Rank 5: Shatter / Recharge Speed

    Increase force and damage to frozen targets by 100%. / Increases recharge speed by 35%.

                                / Recharge Speed: 3.13 sec

    Singleplayer Rank 6: Amplification / Shredder
    Power Concussive Shot with the properties of the active ammo power, enabling it to burn, freeze, disrupt, warp, or pierce armor. / Increase damage to organics by 100% over 10 seconds. Increase force by 50%.

                                 / Force: 600 N (Force & Damage), 510 (Radius)

    Multiplayer Rank 6: Hammer / Shredder
    Increase damage by 50% and radius by 1 meters / Increase damage to organics by 200% over 10 seconds. Increase force by 50%.

    Damage: 400 (Force & Damage), 340 (Radius) / Force: 600 N (Force & Damage), 510 (Radius)
    Radius: +2m (Force & Damage), +3.5m (Radius)

    Concussive Shot becomes a great power on squadmates. It can detonate all power combos and has quite a short cooldown, so Garrus and Ashley become great detonator squadmates. Where it shines though is the Amplification evolution at rank 6. RedCaesar97 at Bioware forums ran a series of tests showcasing properties of the Concussive Shot with different ammo powers and has a full guide here: Link

    I'll quote that guide here, full credit goes to RedCaesar97, of course:

    I like Concussive Shot on a Soldier. It is good for some quick crowd control (with a very quick cooldown) and it can detonate tech bursts. On the surface, the rank 6 evolution Amplification appears to be a good evolution for Concussive Shot.
    Amplification: Power Concussive Shot with the properties of the active ammo power, enabling it to burn, freeze, disrupt, warp, or pierce armor.
    However, if you are going to evolve Concussive Shot to rank 6, is Amplification actually worth taking as an evolution? I ran some tests with the various ammo powers.

    Amplified Concussive Shot with AP Ammo:
    Will Amplified Concussive Shot with AP Ammo penetrate cover? No.

    Amplified Concussive Shot with Cryo Ammo:
    Will Amplified Concussive Shot with Cryo Ammo freeze enemies? Yes. 

    Will Amplified Concussive Shot with Cryo Ammo prime enemies for a Cryo Explosion (test 1)? Sometimes?

    Will Amplified Concussive Shot with Cryo Ammo prime enemies for a Cryo Explosion (test 2)? Yes. But enemies need to be completely frozen, and it can take a long time before they are completely frozen.

    Amplified Concussive Shot with Disruptor Ammo:
    Will Amplified Concussive Shot with Disruptor Ammo set up tech bursts? Part 1 (worse test) No. Lesser of the two tests, used double Chain Overload on both Garrus and EDI.

    Will Amplified Concussive Shot with Disruptor Ammo set up tech bursts? Part 2 (better test) Still No. Better of the two tests, did not use any Chain Overloads.

    NOTE: There seems to be a misconception that Amplification with Disruptor Ammo is required to detonate tech bursts. To prove that you do not need Amplification,  here is a video showing a Soldier with the Viper detonating tech bursts with the Shredder evolution; build is shown at the end of the video. I used Disruptor Ammo to set up the tech burst. Credit to known_hero for suggesting I add this to the post. 

    Amplified Concussive Shot with Incendiary Ammo:
    Will Amplified Concussive Shot using Incendiary Ammo with Explosive Burst explode? Part 1 Apparently not. Kind of hard to tell.

    Will Amplified Concussive Shot using Incendiary Ammo with Explosive Burst explode? Part 2 Still hard to tell. I do not think it does.

    Amplified Concussive Shot with Incendiary Ammo - Damage versus Explosive Burst Comparison. Draw your own conclusions. They look about the same; damage may get the edge.

    Will Amplified Concussive Shot with Incendiary Ammo set up Fire Explosions? Yes.

    Patch 1.04 changed the game mechanics to allow you to detonate fire explosions without requiring you to kill the opponent first with the detonating power. This appears to have brought with it an interesting change: Concussive Shot amplified with Incendiary Ammo can prime and then detonate its own fire explosions. As far as I know, this makes Concussive Shot the only power that detonate itself; all other explosions must be set up and detonated by different powers.

    Amplified Concussive Shot with Warp Ammo:
    Will Amplified Concussive Shot with Warp Ammo detonate biotic explosions? No.

    Amplified Concussive Shot damage multipliers:
    Information courtesy of Athenau from Concussive Shot Amplification gets multipliers against protections.

    • By default, Concussive Shot already has a 4x damage multiplier against barriers (source). This multiplier also does not change when amplified with any other ammo power, including Warp Ammo; the damage multiplier remains at 4x against barriers. 
    • Concussive Shot amplified with Warp Ammo gains a 4x damage multiplier against armor.
    • Concussive Shot amplified with Incendiary Ammo gains a 4x damage multiplier against armor.
    • Concussive Shot amplified with Disruptor Ammo gains a 4x damage multiplier against shields.

    Hopefully this article helped you to discover something new in Mass Effect universe! I highly suggest checking out RedCaesar97's YouTube channel, he has a lot of awesome stuff there :) He also did a playthrough using only Amplified Concussive Shot with Incendiary Ammo. You can find it here: Link
