Why 100% reduced enemy stun threshold makes you stunn every attack?

Doesnt a mob get's stuned if you hit him for more then 10% of his life?

A quote from -> http://en.pathofexilewiki.com/wiki/Stun

The formula used for determining whether or not a stun occurs is: stun_chance = 200 * damage / defender_effective_max_life
..................
If the stun chance would be less than or equal to 25%, it's ignored, so you need to deal more than 12.5% of effective maximum life to have a chance to stun.

So with 100% educed enemy stun threshold the listed things are applied:
1. You don't need to hit the mob for 12.5% of his life in order to have a chance to stun him, but for just 6.25;
2. You won't need need to hit him for 50% of his life to get 100%* stun chance, but just 25% of his life;

* The minimum damage you have to do is 12.5% og the mobs health that goes for 25% chance to stun according to the formula if oyu hit a mob with 5 000 life you have to do 625 dmg for 25% chance to stun and 2.500 for 100% chance to stun as follows:
stun chance = 200 * 625 / 5 000 => 125 000 / 5 000 => 25
stun chance = 200 * 2500 / 5 000 => 500 000 / 5 000 => 100

So why does Kripparian says that you have 100% chance to stun the every mob in the game if you have 100% reduced enemy stun threshold ?

Because if a mob has 1 000 000 life in order to stun him with every hit with 100% reduced enemy stun threshold you have to make 250k dmg for 100% chance of stun which is 1/4 of his health, while as you can see here: http://youtu.be/p2ZSCwTzAd8?t=38s his doing more like not 1/4 but 1/1000 of his life;
SO why is that, what am I missing or I missunderstood corectly reading the wiki?

As far as I am aware, it's 100% of the threshold, not a part of the calculation. Therefore, if a monster has 100k hp and 25k hp hits would stun him, 100% of 25k = 25k so the threshold is now 0. I am sure this is a bug.

The stun threshold is a certain percentage of the monsters hp dealt per hit (I don't remember what it is). Having reduced stun threshold allows for this percentage to drop. Since I do believe it is a linear trend, 100% reduced stun threshold will allow for stuns every hit, but it comes at a massive cost of passive skill points and gear. It is not easy to gain that much stun reduction anymore.

Stun threshold reduction reduces the defender_effective_max_life compared to their actual max life. If that value is reduced by 100%, then by definition it's reduced to 1, and any hit stuns.

That's what you meant, right Mark?

If you reduce something by 100% of its value, it's 0. The defender effective max life here isn't the actual life of the mob, it's just a number used to calculate whether a hit is going to stun.

Exactly, it's a number used to calculate. In the case of damage/defender_effective_max_life, a zero results in an error; in the specific case of 100% reductions, the game often adjusts the value to 1. I remember seeing Mark say exactly the same thing about stun threshold reduction in a previous thread.

If there isn´t any recent changes (no mention in the last patch notes atleast), i strongly disagree.


The cost of 100% stun threshold:




Massive!


P.s. sorry for the sarcastic tone.

The cost of 100% stun threshold:

So the "massive cost" is the 8 passive points (wich also give you 47% increased physical damage) and anything that you cant get from stun gem to gear.

It's a bit funny, that I'm way passed 100% stun threshold. That's without even knowing it. I didn't even think about going for a "stun build". I use the stun support gem, groundslam, and just by going after + phys dmg nodes for mace, I've got 16% + 10%. I did however get the two nodes for just the stun threshold, which is +10% later on. But I actually think I don't need them any more...
So you could say that for just two(!!) extra passive points I got perma-stun.

I just did Vaal at merciless and had him stunned on every singel hit.

My god, that's sums it up, what was I thinking haha

So is this getting nerfed anytime soon or I should go for the build ;p ?

I started a marauder already, but a 2h one because of the nostalgia.
