Iron Reflexes + Leather and Steel

When you convert something, it's affected by modifiers to the thing converted from, and the thing converted to.

If you have IR, your armour is still affected just by increases that apply to armour. You evasion is converted to armour, and affected by any increases that apply to either evasion or to armour.

1) You take your base armour, and apply any increase that applies to armour - this includes Leather and Steel.
2) You take your base evasion, and apply any increase that applies to armour, or to evasion. - this includes Leather and Steel.
3) Add those two numbers together. That's your total armour.

So let's say a duelist or ranger uses gear with armor and evasion. Assume he has total 500 armor and 500 evation.

Case 1: the user doesn't use Iron Reflexes
Case 2: the user uses Iron Reflexes (New Armor = armor + evation)

Math:

Case 1: a) user gets 24% increased armor (1.24 x 500) + 24% increased evation (1.24 x 500)

or b) he gets only 24% to either armor or evation

There is only ONE bonus, and it applies to both armour and to evasion. Armour is increased by the bonus, because it's armour. Evasion is increased by the bonus, because it's evasion.
The numbers match your version a), but your description is inaccurate - there is one bonus, not two separate bonuses.

Case 2: a) user gets 24% increased New armor (500 + 500) x 1.24

or b) he gets 24% to either armor or evation before New armor
ie: (500 x 1.24) + 500 = New Armor

500 base armour is increased by the total of all increases that apply to armour. In this case, the only bonus in play is "24% increased evasion and armour", so that total is 24%. so 500 * 1.24 = 620 armour from base armour.
Base evasion is converted to armour, and affected by all increases that would apply to armour, or to evasion. In this case, the only bonus in play is "24% increased evasion and armour", so that total is 24%. 500 * 1.24 = 620 armour from base evasion.

When you are totalling increases that apply to evasion, L&S is included, because it applies to armour.
When you are totalling increases that apply to armour, L&S is included, because it applies to evasion.
When you are totalling increases that apply to either armour or evasion, which you do for the evasion converted to armour by IR), L&S is included, because it applies to armour or evasion.

A bonus either applies or does not apply. Yes or No. One bonus cannot "apply twice" to one value. Either it applies, or it does not. L&S simply has two cases when it applies - if the thing is armour, or if it's evasion.

Mark_GGG thanks for ur reply. Ur explanation is detailed but without numbers unfortunately. I think people need numbers to understand properly!

I did give numbers - for the first case I said the numbers were sa you listed in your example, and for the second I gave explicit correct numbers.

As stated by u in another thread that the formula used to calculate the total armor when using mixed armor and evation gear with Iron Reflexes and leather and steel would be the following:

Spoiler

http://www.pathofexile.com/forum/view-thread/42605/page/4

Final armour = base armour * (1 + [total increases to armour]) + base evasion * (1 + [total increases to armour and evasion])

if Total Increases to Armour = Armour% + Armour & Evation% from L&S
if Total Increases to Evation = Evation% + Armour & Evation% from L&S
then

Final Armour = Base Armour *(1 + Armour% + "Armour and Evasion%") + Base Evasion *(1 + Evasion% + "Armour and Evasion%")

No. My formula said evasion was increased by "total increases to armour and evasion". You're applying only "total increases to evasion", which is not correct. As I said before, evasion which is converted to armour is affected by modifiers which affect either evasion or armour, not only by those that effect evasion.
This throws off your example with the numbers.

"% Increased Armour" also applies to converted armour, so the correct formula would be:

Armour = Base Armour * (1 + Armour% + "Armour and Evasion%") + Base Evasion * (1 + Armour% + Evasion% + "Armour and Evasion%")

Using those previous numbers, the total would be:

= 1000 * (1 + 68% + 104%) + 1000 * (1 + 68% + 48% + 50% + 104%)
= 1000 * (1 + 0.68 + 1.04) + 1000 * (1 + 0.68 + 0.48 + 0.5 + 1.04)
= 1000 * 2.72 + 1000 * 3.70
= 2720 + 3700
= 6420

If the item was a shield any "% Increased Defences from equipped shield" passives would also be included in both sets of brackets. Each of the % Increases apply only once to a given unit of base evasion, never twice.

This is entirely correct.
