I'm using the Rapid Shadow Strike mainly because of the 80% cooldown reduction if it results in a kill.

Her Master Infiltrator has a built in 25% cooldown reduction.

So, my little brain sees that if she kills someone with Rapid Shadow Strike, it's 80% plus Master Infiltrator's 25% which, providing RSS results in a kill, should mean a 0 second cooldown.

However, cooldown has taken as much as 4 seconds by my unsientific counting.

Are the cooldowns not stacking or are the not supposed to stack? It seems that she's only getting the 25% from MI and the 20% squad tech cooldown from the research.

Multiplicative? Minimum length global cooldown?

With a 9 second cooldown, when you take into account the 20% omnitool tech cooldown reduction, the 25% master thief cooldown reduction, and the possible 80% rapid shadow strike cooldown reduction, you drop the overall cooldown to about 1 second. Perhaps you also have to take into account the amount of time it takes Kasumi to return to her original position after a shadow strike before she can head for a new enemy.

Well, that's 125% cooldown, so even if it was 60 seconds, it should be close to immediate.

I'll check it again, you're probably right about Kasumi returning before the cooldown begins.

I'll give it another look, more carefully this time.

Thanks.

Here's the math:
Subtracting 20% of 9 from 9 gives you 7.2 seconds.
Subtracting 25% of 7.2 from 7.2 gives you 5.4 seconds.
Subtracting 80% of 5.4 from 5.4 gives you 1.08 seconds which is about 1 second.

Then it's just factoring in how Kasumi's movements work into all this. I'm assuming it takes her less than 5.4 seconds to return to her original position, so does the 5.4 second cooldown start once she's returned to position or did it start immediately upon her starting the shadow strike?

I don't know, there are so many other people better equipped for these sort of details.

I remember learning this sort of % math in like 6th or 7th grade. You don't just add them together :/

Shadow strike's a great little power, but I actually ended up liking her anti-Harby flashbang more. Stops him dead in his tracks, and works great on other mobs, too. I think it's even been called "the new Reave" (Gatsby) before.

Re: Flashbang.

Flashbang looked gimmicky to me when it appeared, but boy was I wrong.

Miranda does warp or disrupt, stripping away armor/shield/barrier. Kasumi hits with flashbang. Soldier Shepard pops out of cover and kills whatever's left of the target without even getting shot at. Repeat as necessary.

Then there's the "gift for you" cheery little announcement she gives, which is just precious.

Anyway, back to original topic. Pacifien and epoch_ are right. You don't just add them together. For instance, the probability of flipping a coin and having it come up "Heads" is 50 percent. Therefore, is the chance of getting heads 100 percent if you flip the coin twice? No. It's 50 percent for one flip, 75 percent for 2, 87.5 for three, etc.

I thought it was a 25% chance of having a coin hit head twice in a row. Actually, it's probably not even that, it's some ridiculous calculation I never could wrap my head around. But basically, you have a 50% chance of the coin landing on heads each time you flip it. Assuming the coin has perfect weight distribution if you want to get picky... and assuming a whole bunch of variables stay the same on the part of the coin flipper if you really want to get picky. Anyway 50% times 50% gets you 25%.

Normally, I'd agree, except that BW already said they add all the bonuses together prior to applying them to the base.

He doesn't specify cooldown bonuses, but there's no reason it should be different.

I did another test and paid more attention this time. Once she decloaks after returning to her position, the cooldown is practically immediate. I'll have to try it out  a few more times once I get past this character, but at least this test it worked like I expected it to.

Their math is stupid. :P

Whatever the math is or is not, RGFrog's made a significant finding here.



The shadow strike cooldown begins only after Kasumi decloaks. This significantly slows down the "rate of fire" for this skill compared to other powers. It takes longer to execute.



I still like the power, but this is good info.

On multiple targets with shields down the cooldown AFTER the animation completes appears to be about a second for Rapid. You line em up and she'll pot one every few seconds all night.

Yep, it's good for fire and forget as long as the target is only showing health. She kills, cloaks back to position and is pretty much ready to do it again once she blinks back into view.

In total it takes a bit more time than it does for me to warp/shoot a target, but it's good to point her at something and not have to worry about it.

I guess the wait is a good thing, otherwise I'd use and abuse her from the start of the game :)

Gatsby says flashbangs are overpowered, but I think you can say the same about level 4 of shadow strike.

It works against everything: shields, barriers, health and even armor.

Besides, is not only an excelent offensive move, but a defensive one too.  Kasumi heals while cloaked. In more than one ocassion, I could save her by activating her power. On Horizon, she did a much better job at staying alive and doing damage than Grunt.

Shadow Strike is incredibly useful.
