**Iron Skin or Berserk?**

For a concentrate melee barb would it be better to max berserk or iron skin after these skills:

Concentrate

Battle Orders

Shout

Axe Mastery

I've heard Iron Skin isn't calculated like Shout and Concentrate in that it times the % bonus/100 by the base defense then adds it to the final defense.

If Iron Skin is like Concentrate and Shout then the % bonuses/100 get multiplied by the base defense.

For example:

You have 75 base defense from Dexterity (300/4), and 4000 base defense from armor. With a level 20 Iron skin it multiplies that defense by 2.20, which is 8150 and adds it to the final defense, which is (4000+75)*(Concentrate + Shout + 100)/100. Assuming concentrate and shout are level 20 your Final defense would be 35860.

Now if Iron skin gets calculated like Concentrate and Shout your defense would be (4075)*(290 + 290 + 220 + 100)/100 = 36675

Or if Iron Skin gets multiplied to you base defense then multiplied to Concentrate and Shout then it would be (4075*3.20)*(290 + 290 + 100)/100 = 88672

On my character I have level 33 shout, 8 iron skin, and 29 concentrate. Dexterity is 287. My total defense without concentrate is 17093. With concentrate it is 27570. My defense on my items is 2686. So the equation would be either (2686+71.5)*(380 + 100 + 420 + 100)/100 or ((2686+71.5)*2)*(380 + 420 + 100)/100 or [(2686+71.5)*(380 + 420 + 100)/100] + [(2686+71.5)*(100+100)/100)].

After I checked it, it is (2686+71.5)*(380 + 100 + 420 + 100)/100 so iron skin is calculated like concentrate and shout. So would it be better to have max zerk or max iron skin for melee? Now, with level 27 iron skin, 33 shout, and 29 concentrate I would have: (2686+71.5)*(380 + 290 + 420 + 100)/100 = 32814 defense.

When looking into Concentrate in duels I do 941-2978 with 95% deadly strike. My average damage would be 1959.5*1.95 = 3821 and 20% of that damage is magical damage.

If it was all physical and dueling someone with 50% damage reduce, I would be doing an average of (3821)*(1/6)*(1/2) = 318 damage

Now since it is 20% magical damage my physical damage would be (3821)*(1/6)*(1/2)*(4/5) = 254 and my magical damage is (3821)*(1/6)*(1/5) = 127. After adding those together my final damage is 381 damage.

So my final question is: Is the extra 5244 defense on iron skin better than the extra 63 damage from the 20% magical conversion on concentrate?
