Power Efficiency...What's the Deal

So after testing a few things out it seems the most power efficient you can make your skills is to reduce their cost by about 50% If there's some kind of soft cap in place for this I guess that's fine, but if there isn't then this would and should be considered a bug. I've stacked upwards of 200% power efficiency on a frame and not seen my costs go lower than 50%

(I will here on out refer to Power Efficiency as PE)

What's even more interesting is that the calculation in general seem to be off. For example I have a 48.5% PE mod on my Ash. If we were to use a Shuriken, which costs 25 energy, then our total cost would be 12.8 rounded up to 13. Yet when I use Shuriken my cost is 17 energy. That's a reduction of 32% not 48.5% !!

Just to entertain the subject further I added a 30.6% PE mod in with the 48.5% one and now my Shuriken cost went down to 14. That's only an additional 20% reduction not 30.6%!!

Since I'm never satisfied with results I tested this out on other warframes and had the same results

So if someone here can clarify what kind of funky &#! math is going into these PE mods it would be helpful. If a mod or admin or staff can clarify that these calculations are correct and working as intended that would be helpful too, because to me this looks to be bugged. If PE mods are working as intended Then I feel the proper numbers should be displayed on the mod so as not to confuse people into thinking they can get half priced skills.

you are missunderstanding how PE works. by your logic 100% PE would mean 0 energy cost (if there were no cap). But that would be power cost not effiicency. 100% PE means that you can use an ability 100% more often with the same amount of energy. Basicly 100% PE = 50% power cost.

to demonstarte on your example:

25 / 1.485 = 16.835...

25 / 1.791 = 13.958...

btw: this is not a soft but a hard cap

Might be wrong here, but it could be that power efficiency is only working on 50% of your energy cost

Skill one = 25 Energy cost

50%= 12,5

PE: 48,5% of 12,5= 6,0625

New Cost

50% + (50%- 50%x 48,5%) = 12,5E + 12,5E - 6,0625E = 18,56E

PE: 30,6% of 12,5=3,825

50% + (50% - 50% x 30,6%) = 12,5E + 12,5E - 3,825E = 21,175E

Both mods

50% + (50% - 50% x 79,1%) = 12,5E + 12,5 - 9,8875 = 15,1125E

There is still an error of around 1E-2E, close enuff for me, never been a math type of person, but i saw the pattern...

25 / 1.485 = 16.835...

25 / 1.791 = 13.958...

you, sir, are right, stupid me

Thanks for clearing the math and usage up bud =)

I still don't think there's anything efficent about it when you need to take a 1/4 of you mod slots to gain a decent benefit from PE. They possibly need to slighty raise the max amount that shows up on mods or change the calculation altogether.

Well, 25% PE equals 50 power max on a 200 energy warframe. Not totaly worthless, but i could think of better alternatives.

Oooo Oooo wait wait let me guess, I love guessing games. By alternatives do you mean things like...oh idk making your skill tree have nodes that actually reduce the cost straight up and get rid of the mods altogether?

Holy crap did I like solve two stones with one bird right there or what? I came up with a start to fixing the junk skill trees AND eliminated a doo doo mod in the process.

I don't know where it comes from sometimes... I scare myself even.

=P

Maybe I don't have any power-issues so I would go for 100 shield or maybe 75 health or god forbid 75% melee damage...

It was about an alternative mod, not an alternative solution for PE.

Oh dammit and here I thought I was reading your mind. You not having any energy problems insinuates, to me anyway, that you don't use your skills very often and let your overpowered weapon do the talking by liquifying anything you shoot it at. I find that to be another problem in itself. The game is far too gun-centric and unless completely surounded by mobs do players end up pressing 4 to = win or using any of their skills. Sure there's iron skin, snow globe, decoy and things like that, but those skills aren't needed if everyone can just pull the trigger and watch things melt in senconds.

I feel that serious changes need to be made to mods in genereal, but that's a whole other beast that I wont go into in this topic. Suffice to say I think PE should be done away with and your energy should regen slowly with mods that boost the rate. I also think powers should play a larger role in the game other than one shotting everything on the map or making it easier to revive allies. Nyx was a good step in that direction, but clearly needs more work.

You also talked about alternative mods, which I know most will agree, are pretty much Sheild + and Sheild recharge with sprint speed tossed in there. It's pretty freakin stupid when I spend my 11 slots to boost my sheild to ridiculous size and make myself fly around the map rushing through levels. Now I don't HAVE to do that, but what i'm saying here is it's the norm now. Melee damage? What the point or incentive to use it when you can just blow everything away in a few shots. Starting to go into mods in general now so i'll stop it there.

Anyway tl;dr

PE mods should go away and energy should regen naturally with mods that boost the regen rate.

Apparently you didn't catch anything tha was talked about in this topic. Lol that's okay =)

Oops, I think that dog fart stuff just short circuit my brain :P

I object...with a 29% mod at rank 30.

http://puu.sh/1Znsi

Might be the same case as Multishot which use to be 99% at rank 30 but now is around 70~% at 30. BL GUYS.

Frame/weapon specific mods seem like they can still go up to 100% -- got a 99.8% multishot for Latron the other day. Does anyone know if power efficiency can appear on frame specific mods, or if it can only appear on generic warframe mods?

I really don't understand the frame/weapon specific mod. A few of my Rhino mod give as much as generic warframe mod.

Also I do see a guy with 99% generic shotgun multishot mod on his Hek in the thread about op mod.

Does this mean some of the old mod didn't get nerf? That's... uh....

Multi is still att 100% being the highest

PE currently caps out at 50% top on either warframe specific mods on general ones. You will need 2 of those if you want to half your cost on skills as it stands right now. See above for details on how it all works =P
