What is Coup de Grace?

Post by trihero »

I haven't actually tried the move on the shinobi - is it a melee move? A shot from your gun? What's the cooldown; any aim penalties/bonuses? Any good use in practice?

Coup de Grâce works for both mêlée and ranged attacks. It is activated against any disorientated/stunned/unconscious target.

You have two checks:
The base chance is 25% for disoriented and 50% for stunned/unconscious target.
Then you may get up to 75% additional chance depending on the target's remaining health. In theory you may go up to 125%.
There is no cooldown on it.

It is a nice ability to try and finish off big buffy aliens, like Berserkers, Hive Queens and others. It works better on organic enemies since they are the once that can get disoriented and also influenced by Psi abilities.

Coup de Grâce also works on mechanical units but they are a lot more difficult to stun. A stun hack will work though, so you might have a Specialist hack that Sectopod and then let your Shinobi finish it.

This essentially gives the Sniboi an ability to deal with high-HP enemies that is on part with Kubakiri for the Sharpshooter.

Coup de Grâce works for both mêlée and ranged attacks.
What does this mean? Do you choose whether to use melee or your gun? Does it have an aim chance? (affected by cover, your aim, etc)? What is the "range" on it; for instance if you are 5 tiles away from a sectoid who got stunned and it's behind high cover relative to your shinobi, can you use coup de grace on it from 5 tiles away behind high cover is there a penalty to aim etc?

My bad, Coup de Grâce only works in mêlée range, just tested it ingame. It uses the same effect as the Repeater had in original XCOM 2, but apparently only for swords and axes.

In real life Coup de Grâce usually is delivered by a firearm, since not a lot of people know where to strike to deliver a mortal blow.

How do you use it:
- Run next to your target.
- Pick Coup de Grâce from the menu bar.
- Activate. It is a turn-ending action, unlike Slash.
- As Slash though, there is no cooldown so you you can use it each and every turn.

I have used it only once on a MEC and I was already near it, so that is why I probably thought I can use it on the other targets as well.

It works like a charm though, especially on bigger targets.

Ok thanks, so just to check you can't "double dash and coup de grace" like you can fleche? It has to be a blue move + coup de grace?

So if you activate after moving that means it can't be used on a Yellow move, like Flesche?

Therefore, how do you use it on a flashbanged enemy who's outside of a Blue move?

Oh man. Well this is helpful to know now :( . I assumed it was bugged since the button never highlighted when there were available targets both melee and gun. Bah! The question about how to use it outside of half range is a vital one - anyone know? It would seem a dubious talent choice if it can't be used at full range.

Yep, if you are not next to the target you can only use a blue move. :)

You can use an officer to Command the Shinobi, or if you are lucky via the AWC tree you can get Run and Gun (should work in theory, as you can even use pistols when activating it).

That said, it has great synergy with the Arc blade (25% stun) and an Arc Thrower Assault.

If you want to use this skill I strongly suggest you only use the Arc blade, as you can stun someone with a regular mêlée attack and then try to finish him off on your next turn.

Implacable is also a must.

Two more questions

1) does Coup de Grace work on frozen units?

2) is Coup de Grace a "turn ending move" even though it costs 1 action point? (i.e. if you started the turn next to a stunned unit can you coup de grace twice on it without command? I assume yes with command)

Ok so my remaining questions are

1) does it work on frozen units (frost bomb)
2) does it interact with your aim stat in any way / does it do a normal slash damage/hit if you don't execute the unit?

So far i found Coup de Grace very underwhelming :(
You need a setup, you can't use it like fleche in a yellow move, it is not guaranteed to work and if it doesn't, it does less than fleche.
In the perk tree it is up against conceal, a very valuable perk.

Coup de Grâce should work on frozen units as they count as stunned for ingame purposes. I will test it later today once I get back home.

The ability is essentially Slash + a Repeater check. Here is how it works in practice:
- You move next to the target.
- Click on the ability and the targeting interface will show. You will see Aim, Damage and Crit chance. If you have at least an Arc blade and well-rounded Kensai that Aim chance will almost always be 100%, considering that the target is disorientated/stunned/unconscious and thus has no defence.
- Activate it. The game will first roll the Repeater check and if successful, you will see the green icon Executioner and the target will be slain.
- If not, you will do a regular Slash damage hit (and possibly a Crit hit).

Thus if you Command the Shinobi, you can blue move next to the target, first do a normal Slash and then activate Coup de Grâce. As you have wounded it, the proc chance will be higher.

The idea behind Coup de Grâce is to eliminate High AP and/or Armor targets with one or two hits, not to do the most damage possible. Later in the game with the latest Arc Thrower you can even attempt it two turns in a row as the alien will be stunned for 4 actions.

One day I'd like to try it, but I don't want to spend 30 days retraining my shinobis just to get it (or fuss around with ini settings). Thanks for the info, I'll be waiting to hear about your frost bomb exploits.

Seems like the ultimate alien ruler killer (unless it has some sort of limitations like kubiri on alien rulers?)

I'm assuming the bonus chance is a linearly scaling thing? Aka if the enemy has half of their health remaining, then you get half of the maximum 75% bonus = 37.5% + 50% = 87.5% against a stunned target with half health?

It's too bad it doesn't work on burning/poisoned units, kinda feels like it should.

Tested it tonight, unfortunately it does not work on frozen targets. Guess you will have to make sure to have an Arc Assault on your team just in case.

So is the additional chance proportional to missing HP? As in, missing 50% of HP, 50% additional chance?

Seems...ok. Sadly sectopods will blow you up if you do this to them :/

Well that was my thought too, except your numbers are a bit off, since the max bonus chance is 75% explicitly so missing 50% = 37.5% additional chance is my best guess.

For the exact algorithm someone will need to open the related script and check how it calculates the proc chance.

In theory if the target is at 50% you will have at least 25 % base chance + 37,5 % wounds = 62,5 %

Oh, was hoping it was 75% max at 25% HP and didn't improve thereafter.

If they have to be at 33% HP for a gauranteed proc, I don't like this ability at all. It's uses are basically...hive queens. Or rolling the dice if you feel lucky, I guess. I don't like rolling the dice with melee characters :?

The base chance is 25% for Disorientated and 50% for Stunned/Unconscious.

So if you stun the target and wound it to 50% HP you should have 50 + 37,5 = 87,5 % chance.

Please note that even if unsuccessful, you still do a regular Slash hit against a disorientated/stunned target. It is not like the target itself is going to do something to you on its turn. You can then simply kill using regular mêlée attacks on your next turn if you do not want to disorient/stun it again.

Frankly I find it to be one of those Rube Goldberg components that's mutually exclusive with a dead simple and super effective ability and as such worthless.

So your chance to succeed is only 25%/50% (plus something mysterious) and you can only use it when within a single move of the target. So very situational AND unreliable. So not that tempting as a high level perk.

Unlike Kubikiri which, if it worked as designed, is possible to design around by crit stacking.

Hi,

the description was not totally understandable in the game. I thaught Coup de grâce only triggered when the ennemy's HP was 50% or lower.
Reading your posts, it seems to work all the time, or at least, as soon as the alien had been hit once.
Could you confirm ?

It is not the purpose of this post, but, can someone explain to me how kiriburi (or whatever it is called :D ) work ?

Thank you

Coup de grâce only requires that the unit is disoriented or stunned. The chance to kill is starts at either 25% or 50% for disorient or stun. On top of that you have an increasing chance as their HP gets lower. Of course your sword attack is going to kill anything below a certain point anyway, so it's mostly only useful against things that have high HP.

Kubikuri is an attack against everything in sight that has less than full HP. If you land a crit it dies, if you don't you do half damage. In theory a quite powerful ability, especially if combined with cover destruction. A good sniper can hit 80% crit against everything that is exposed and 40% against everything else. I haven't tried it out myself, but some complaints seem to be that it doesn't always kill on crit and thus is 'bugged'. Also it competes with HI which combos really well with Serial.
