Armor and Evasion percentage mods on Flasks, they stack??

So I just watched a vid on youtube here: http://www.youtube.com/watch?v=rj4b19yl2To.

This guy has an Iron Skin (100% armor) granite and another granite that gives percentage evasion. He said that if you use both flasks together, the effects stack with eachother. He is running Iron Reflexes so he would get the percentage effect from both flasks if used at the same time? That's pretty cool.

Just thought if anyone had feedback about this.

With IR, your evasion is increased by the evasion modifier, and by the armour modifier, yes. He probably shouldn't use it on two granites, though, since using one will 'overwrite' the other afaik. He should use a different type of flask for the evasion bonus.

The bonus evasion from the granite flask won't increase the armour from granite flask, though.
Face it, all of your suggestions are worse than this idea:

But he's saying that it will stack. Like if u had 90% armor mod on one granite, and the other had 90% evasion mod, if u use both it would give u a total of 180% armor.

The implicit effect of the granite (the +3000 base armor gained from each granite) does NOT stack afaik. But the other mods I think do.

I'm gonna test this out.

Wrong

Armour = BaseAR * IncreaseAR + HasIR(is 0 or 1) * base EV *IncreaseEV * IncreaseAR

Oh, thanks! So let me try putting in the numbers. Lets say you have 1000 evasion and 200 armor with a 100% percent mod on both evasion AND armor.

Armour = 200 * (1+1) + (1 * 1000 * (1+1) * (1+1))

Is that the right equation?

If my calculations are correct that would give you 4400 armor. That's not including the implicit armor given from the granite effect.

Yup. So you have 1k base EV. YOu have 100% increased EV, so you actually have 2k EV. This is changed to armour. As such it is effected by Increased AR, so you get 4k AR. Regular 200 armour is effected by increased AR, so it becomes 400.

So having a +Ev and a +AR on two seperate flasks means you end up with the EV being increased by both. If the majority of your AR is from EV thsi can be powerful. If its mostly from AR, it will do very little. But when you consider determination and grace combo, yeah
Seriously? Increased armour and increased evasion are multiplicative with each other with IR? That is so mentally broken. If that is the case (I don't think it is), then why didn't they just nerf that, instead of the dex nerf? O.o

They are not. 'Increased' is always additive.

(base + gear + Grace) * (Increased Evasion + Increased Armor and Evasion + Increased Armor) * More Armor = Armor Rating from Evasion.

No, they are not and never have been. That formula is incorrect.

Total armour under IR is
armour = base_evasion * (1 + [total all increases that apply to armour or evasion])
+ base_armour * (1 + [total all increases that apply to armour])


Base Armour (including that from flasks) is still only affected by modifiers to armour. evasion modifiers will not affect it.
Base Evasion is affected by any modifiers that affect either evasion or armour. All additive increases stack additively. No modifier can apply twice (for example, "% increased evasion and armour" or "% increased defences" are a modifier that applies to armour, so affect base armour, and they're a modifier that applies to evasion or armour, so apply to base evasion. They do not get doubled and apply twice.

my bad, expanded brackets badly, and failed at actual calculations
