Frost Aurora Helmet Stats And Uses

[Dermind]

I have done some searching and im a bit confused with this one

1. the helmet has +25% armor -5% health (but i have seen some pages and calculations being done with a 33% armor increase (has the helmet changed and those are old ones?)

2.the calculations that i have seen suggest that the helmet decreases the damage taken by 5%, as much life as you lose, are these correct and if they are whats the point then? (with steel fiber the damage redaction seems even less)

3.I kindly request the mathematic formula (it will save some time rather than just stating the results)

4.I checked past forums talks but i havent fount something helpful, so if this has been discussed elsewhere sorry for making this post, just post a link

I think you will rot waiting for a formula...

[Dermind]

Seeing it written is a start : p

Thought a link to page that surely has it right cant be that rare

[litlit]

Here's the formulas https://docs.google.com/spreadsheet/lv?key=0Au6mBXle3cFtdHBYUzVJaDJfdkIzSEN1cUh5UlRvckE&f=true&noheader=true&gid=9

 

Rhino and Frost have a base 150 armor. Saryn has a base 125 armor. Every other frame has 10 base armor.

According to that (which has been accurate so far), the Aurora helmet is +25% base armor and -5% total health.

 

Regarding how armor affects how much health damage is taken, I have no idea how it works :P

wat

 

-5% total Health?

 

What tomfoolery is this?

It should be -5% base Health, surely?

Helmets are calculated last and affect stats after mods.

 

To OP: Armor acts as a multiplier to the damage you're taking on your health. The formula for the multiplier x is:

 

x = 100/(armor value+100)

 

Frost has a base armor value of 150, giving him 60% damage reduction. Aurora increases that armor by 25% to a total of 187.5. This will give you a damage reduction of 65.2%. Your effective hitpoints will increase by ~10% after the incorporation of the '-5% total health' stat, meaning that you should always use Aurora over the standard helmet.

 

Edit: If you're concerned about survivability, that is.

Unless you mean -5% of base health by calculating the number and then decrease it from the total, taking it out from the base would be the same since the mods would increase the new base health

eg 150 hp (with vitality max) + 440% = 810  -5%  = 769.5

     150 hp -5%  = 142.5       + 440% = 769.5

so only 150+440%-150*5% would make a difference = 810 - 7.5 witch is too low to even count as a decrease

As for the 60% damage reduction without the helmet and the 65.2% damage reduction with the helmet (these are the results i also got so far and thus, made this post) how does that make my effective hp to increase ~10% ?

if i have 150 hp and i get a 100 damage hit with no armor i lose 100 hp, if the damage reduction is 60 % 100 -60% = 40 damage

if the damage reduction is 65.2 then i get hit for 34.8 damage 

so 150 hp -100 (no armor at all) =50 hp remaining

150 -40 (normal frost armor) =110 hp remaining

150-5%=142.5 (aurora debuff) -34.8 (frost armor +aurora buff) =107.7 hp remaining 

Ether i understood wrong what you wrote, or the hp i have after the same hit with aurora leaves me with less hp than without it

Yeah, you clearly don't understand what effective health is.

 

-_-

 

Do the math on if you get hit by another 100 damage attack.

 

Then another 100 after that.

 

Then another 100 after that.

 

Aurora helmet is still alive. Normal helmet is dead.

effective HP before Aurora = x1; effective HP after Aurora = x2; total HP before Aurora = h; total HP after Aurora = 0.95 h; damage taken before Aurora = a1 = 40%; damage taken after Aurora = a2 = 35% (approximately)

 

x1 = h/a1 = h/0.4 = 2.5 h

x2 = 0.95 h/a2 = 0.95 h/0.35 = 2.71 h

 

x2/x1 = 2.71 h/2.5 h = 1.086 -> 8.6% effective HP increase

 

I was a bit generous when I said that it's a 10% increase, I'll give you that.

 

Edit: You'll get to a 9.25% increase if you use the exact value for a2.

 

Yeah, you clearly don't understand what effective health is.

The problem is that the increments in which you'll be taking damage are usually small - unless you decide to get melee'd by a lot of doods.

Indeed, i didnt consider the difference it would make on the total of my hp

So without steel fiber you get 8 to 9 % effective hp increase and with max steel fiber (110%) you get 4 to 5% effective hp increase?

Does that apply to all kind of damage (bullets,rockets,flamethrowers,laser doors,poison from ancients e.t.c.)?

Yup. Most of the helmets have downsides that calculate from the total, yet the bonuses are from base. Not sure why, it just feels really stingy.

Your maths seems off. I'll do the calculations...

 

Assuming Aurora bases on armor before Steel Fiber:

total armor before Aurora = 150 [base] + 165 [steel Fiber] = 315

total armor after Aurora = 150 [base] + 37.5 [Aurora] + 165 [steel Fiber] = 352.5

 

damage taken after armor w/o Aurora = 100/(100+315) = 24.10%

damage taken after armor w/ Aurora = 100/(100+352.5) = 22.10%

 

EHP increase: 0.95*0.2410/0.2210 = 1.036 -> 3.6%

 

Assuming Aurora bases on armor after Steel Fiber:

total armor before Aurora = 150 [base] + 165 [steel Fiber] = 315

total armor after Aurora = 150 [base] + 165 [steel Fiber] + 78.75 [Aurora] = 393.75

 

damage taken after armor w/o Aurora = 100/(100+315) = 24.10%

damage taken after armor w/ Aurora = 100/(100+393.75) = 20.25%

 

EHP increase: 0.95*0.2410/0.2025 = 1.130 -> 13.0%

 

I'm inclined to say that the first value (Aurora before Steel Fiber) is correct - but I'm actually lacking the empirical evidence or a source to cite. It does, however, affect ANY damage taken you take to your healthpool (laser barriers do not damage your health...).
