~50% physical damage reduction (from life) - no armor

So, unless I'm mistaken about how some mechanics work, it looks like its easily possible to always have ~50% less physical damage taken. Using Mind over Matter, Cloak of Flame, and a few endurance charges should allow this to work, but high mana regen and large mana pool would be required to sustain.

Cloak of Flame - 20% of physical damage converted to fire
Mind over matter - 30% of damage taken to go to mana
Endurance Charge - 4% physical damage reduction per charge

So, if I have 5 charges up, and I get hit for 1000 damage (0 armor), the following will happen:

Damage reduction is applied: 20% from charges gives a total of 800 physical damage.
Cloak of Flame conversion: 640 physical damage and 40 fire damage, assuming 75% resist.
Mind over Matter: 448 physical damage to life, 28 fire damage to life, 192 physical to mana, 12 fire to mana.


Now, lets add a level 16 AA to the mix. This happens after reduction but before MoM. Level 16 gives -120 to fire and physical.

So, that means that 520 physical and 0 fire before MoM. After MoM it leaves 364 to life and the rest to mana. This is only 36.4% of the original damage taken with zero armor.

Redoing the numbers for the following size hits and level 16 AA:

2000 damage: 812 to life, 348 to mana - 40.6% to life (59.4% reduction)
5000 damage: 2212 to life (56 is fire), 948 to mana (24 is fire) - ~44.2% to life (55.8% reduction)
10000 damage: 4592 to life (196 is fire), 1968 to mana (84 is fire) - 45.9% to life (54.1% reduction)


Now, lets look at how much armor would be required to mitigate these hits to a similar level, without MoM, AA, but with the 5 endurance charges.

For the 1000 damage example, only 364 was taken to life, which is 63.6% reduction. Since the charges give 20% flat reduction, lets take that out. We need 43.6% reduction from armor. Given the below armour formula, lets calculate.

reduction = armour / (armour + 12*damage)

.436 = A / (A+12000)
.436A + 5232 = A
5232 = .564A
A = 9276.6

So, roughly 10k armour, which isn't too hard to get. I'll go through the same calculations with the other hits.

59.4% reduction from 2000 = .394A + 9456 = A; A = 15.6k armour
55.8% reduction from 5000 = .358A + 21000 = A; A = 32.7k armour
54.1% reduction from 10000 = .341A + 40080 = A; A = 60.8k armour

So, the thing about the higher hits is that you'll probably run out of mana unless you have a huge pool with no auras, so the numbers might not look as good as they are here in a vaccuum. But, based on the armour calculation numbers, it'll be hard to mitigate that much on your own.

Now, get MoM, AA, Cloak of Flame, AND a high armor shield with some bonus armor nodes, and you got a stew going.

I hope these numbers are correct and my understanding of mechanics isn't flawed. If any of this is wrong, feel free to correct me. I'd like to try a build based around this idea and see how it performs.

Also, what is a typical 'large' hit in maps? Does it reach 10k?

Edit: fixed calculations based on below reply.

Endurance Charges are first. 800 melee damage.
Then Cloak of Flames. So you're at 540 physical and 40 fire.
Then arctic armor. Level sixteen is 158, so 382 physical, 0 fire.
MoM then reduces this to 267, presuming you have the mana required to eat that cost.

The results are better than you calculated.

Thanks, fixed. Numbers are very similar

Also, level 16 AA is 120 reduction, 158 mana degen.

Damage going to your mana is not damage mitigation. Mind over Matter effectively makes your mana double as extra life as well, not as damage mitigation.

If you have high enough mana regeneration it is applicable for this demonstration.

I imagine the -60 Lightning resist from Lightning coil, and the lack of any other valid effect of benifit makes it a Unreasonable alternative.
although it would be twice as much mitigation its a 110 resistance difference that you would need to make up.
Also I guess Darkscorn would grant 25% free metigation if you also use CI, Although just natural block would grant a larger benifit.

I'm using Lightning Coil on a melee fighter with no armor or ES, and it's pretty miraculous. It did require the +20% Elemental Resist from Shields nodes, and around +100% Lightning Resist on gear. Purity is also a must-have, and I recommend getting Elemental Adaption to take you up to 79% Lightning Resist.

No, it's still not mitigation. What you have there is mana regen acting as life regeneration. Life regeneration, while nice, is not mitigation.
