Among all damage debuffs in the game - Tactical Scan stands heads and shoulders above the rest ...Did notice in game my claymore was doing suspect amounts of damage to boss type enemies fired from cloak with TS debuff on - so I decided to test why that was happening ...


Summary
- The weapon damage bonus is applied as a HeadShot multiplier (up to 32.5% weapon damage global multiplier in case of body shots and up to 250+32.5 = 282.5% in case of headshots...By making it additive with the headshot multiplier they managed to give it very good damage boost vs body shots and not cause it to do astronomical amounts of damage in case of headshots ) EDIT - this works the same for all debuffs
- BUG: The 25% to all headshot damage perk does nothing ...
- The 40% DOT evolution for arc grenades applies to total damage - adds a lot of damage (especially to arc grenades fired from cloak on TScanned target)
- the weapon damage bonus is applied before Armor DR substraction (very beneficial vs armored foes for all squad // In other words headshot bonuses apply before armor DR)



WD -  Weapon Damage % bonus
TS -  Tactical Scan
TC - Tactical Cloak
HS - Headshot 
SR - Sniper Rifle (% Damage bonus)
PD - Power Damage % bonus

TEST QMI

TC 80% ; *1.25 SR
TS All damage 25% , 7.5% WD , 25% HS
WD 22.5%
PD 20%
Arc Grenade 400 *(1+0.2+0.3) + 400 *(1+0.2+0.3)*0.4 DOT
20% HS passive

Weapon Raptor X 97.7 (eb 25% WD)



Heavy melee = 1350 - 750 = 600

------
Light melee TC OFF, TS ON

Measured
1350-1162.5 = 187.5
Calculated
150 * 1.25 = 187.5 OK
//as in TS affects melee damage

--------
RAptor body shot TC OFF , TS OFF

Measured
1350-1205.8925 = 144.1075
Calculated
97.7 * (1 + 0.225 + 0.25) = 144.1075 OK

-------------
RAptor body shot TC OFF , TS ON

Measured
1350 - 1159.0576 = 190.9424
Calculated
97.7 * (1 + 0.225 + 0.25) * (1 + 0.25 + 0.075) = 190.9424

// 32.5% GLOBAL MULTIPLIER TO WEAPON DAMAGE - INSANE :) ...And its party friedly ...Best boss kill debuff in the game ...


------------------

RAptor body shot TC ON , TS ON

Measured
1350 - 981.8694 = 368.1306
Calculated
97.7 * 1.25 * (1 + 0.225 + 0.25 + 0.8) * (1 + 0.25 + 0.075) = 368.1305 OK

-----------------

RAptor HS shot TC OFF , TS OFF
Measured
1350 - 940.8812 = 409.1188
Calculated
97.7 * (1 + 0.225 + 0.25 + 0.2) * 2.5 = 409.1187 OK

-----------
HS (TC OFF, TS on)

Measured
1350 - 887.6958 = 462.3042
Calculated
97.7 * (1 + 0.225 + 0.25 + 0.2) * (2.5 + 0.325) = 462.3041 OK
// TS HS PERK 25% extra damage does nothing
----------
HS (TC ON TS ON)
Measured
1350 - 496.1173 = 853.8827
Calculated
97.7 * 1.25 * (1 + 0.225 + 0.25 + 0.8 + 0.2) * (2.5 + 0.325) = 853.8827 OK
// TS HS PERK 25% extra damage does nothing

-----------------------
HS TC ON , TS OFF

Measured
1350 - 594.3515 = 755.6485
Calculated
97.7 * 1.25 * (1 + 0.225 + 0.25 + 0.8 + 0.2) * 2.5 = 755.6484 OK


---------------
Arc Grenade + Dot (vs health) HS TC off , TS off

Measured
1350 - 398.0002 = 951.9998
Calculated
(400 * (1 + 0.2 + 0.3 + 0.2)) + (400 * (1 + 0.2 + 0.3 + 0.2) * 0.4) = 952
//The 40% DOT evolution for arc grenades applies to total damage - adds a lot of damage


-------------------
Arc Grenade + Dot (vs health) HS TC off , TS on

Measured
1350 - 160 = 1190
Calculated
400 * (1 + 0.2 + 0.3 + 0.2) * 1.25 + 400 * (1 + 0.2 + 0.3 + 0.2) * 1.25 * 0.4 = 1190 OK

---------------

Respeced to test bug - removed 25% to headshot damage from TS and rank 6 cloak evolution (I play the QMI with a claymore)

Measured
1350 - 666.8938 = 683.1062
Calculated
97.7 * (1 + 0.225 + 0.25 + 0.8 + 0.2) * (2.5 + 0.325) = 683.1061 OK BUG confirmed

----------

Claymore X test Vs Silver Brute (30 DR)

(same char same setup with 7.5% Shotgun Damage from gear)

Measured Damage(7500 - 2608.5390) / 8 = 611.4326
Calculated per pellet
206 * (1 + 0.225 + 0.25 + 0.075 + 0.8) * 1.325 -30 = 611.4325

 the bonus damage is applied BEFORE armor DR substraction - very beneficial

Excellent work.

.....I guess that's one more reason to not take headshot damage...

I love all the stats OP. But if you put in your thoughts conclusions on what they represent it would help the average joe who comes to these boards. Just a helpful hint for you.

That is a lot of math... So I'm going to go on a limb here and guess that Tactical scan is.. good? And I should use it more than I use it now.

I used to use tac scan a lot but now I only have it on my engineer and only up to 3. I would much rather max out the passive on my infiltrator.

As always, awesome work and much appreciated!

And the lesson here is that I need to be using TacScan more often. I tend to use it on the occasional boss, but it should be slapped onto every boss, every time.

Oh, and here's a thought. Will the debuffs from Cryo Blast, ProxMine and TacScan stack? If so, then a HInfil, GI and MQI may be the debuff team from hell for Banshees and Atlases.

Only remember testing Warp debuff & proximity mine debuff in SP and they did stack multiplicatively ...

Now even if they don't all stack multiplicatively to up damage to obscene amounts -worse case scenario they  stack additively ..


EDIT Tested in an different thread - all debuffs stack additively with the headshot modifier ...

So Tac Scan is really meant for bosses and maybe a Phantom - its not worth wasting time activating it on anything that can be headshotted given the delay/lag for it to kick in.

Also should be noted that there's a range limitation on larger maps, you can't Tac Scan a target all the way across the map (probably similar to other power lock on ranges).

I got 4 on my MQE and 0 on my MQI

Yeah, and that's a pita!

Hmm. . . I would've liked to see the number breakdown for:

Arc Grenade + Dot (vs health) HS TC on , TS on

Or does Tactical Cloak not apply damage to grenades?  I thought it did, but come to think of it, I really don't know.

(400 * (1 + 0.2 + 0.3 + 0.2 + 0.8) * 1.25) + (400 * (1 + 0.2 + 0.3 + 0.2 + 0.8) * 1.25 * 0.4) = 1750

Great post, and Tactical Scan is awesome, but to call it the best debuff may not be that accurate, really.

Proximity always takes the cake for me.

First, OP, thanks for the post, I really appreciate having data to base my evolution choices and game play on, as opposed to a lot of wishful thinking on my part on what works and why.

When I unlocked the MQE (shortly after I started to play MP), I didn't use TS, but used Incinerate a lot. Later, learned the benefits of TS and used it a lot, mostly on bosses, ravengers, phantoms, nemesis and maybe the occasional hunter or pyro. I got into the whole incinerate thing not working properly, which was supposedly about server lag. It was frustrating. Then new characters came out and I didn't play MQE for a long time.

When they buffed Incinerate, I went back to the MQE to check out how it worked. In my experience, if I DON'T use TS, incinerate works fine and the buff is nice. However, once I use TS, a lot of times it makes Incinerate go "stupid" for the rest of that match, whether I have TS active or not.

I tried it out over several matches, both as host and as client. Incinerate generally worked fine, until I used TS. This is not to say that Incinerate (or Concussive Shot or Carnage or Throw or any other "ballistic" power) cannot go stupid all on its own, but it seems to go stupid more often after I've used TS. For me, is I either choose TS or Incinerate, but don't use both in the same match.

By "stupid" I mean it either won't track a target, won't hit a target, won't cause damage even if it hits a target, even point blank. Sometimes zooming in with your weapon before launching Incinerate, sometimes not.

Bottom line, it really reduces my desire to use the MQE. Which is a pity, because it can be a lot of fun to play that character, when all the pieces and parts work as they are supposed to.

Thanks to peddroelmz for all his hard work =) I think he should start his own ME3: MP Mythbusters series ^^

I noticed it seemed to be adding quite the massive boost while testing out Incinerate on a QME. How's the math on the power damage evo look?

I have never experienced this with the MQE whether host or off host.

Excellent work OP. I have tac scan maxed out on both male quarians. For fitness you really only need up to level 4.

Same thing happens with Cryo Blast and Incinerate on the QFE. Sometimes, Cryo Blast cause the target to not be trackable by Incinerate.
