[Question] Critical Strike per-action versus per-monster basis

I welcome you.

I have recently gotten more interested in the mechanics behind critical strikes. My xperience made me believe that critical strikes are rolled per action as also seen on the wiki page:

Critical Strikes are rolled on a per-action basis, not per-monster. So each time you use a skill, the Critical Strike roll is made once and only once. If you roll a Critical Strike, you will deal Critical damage to all enemies hit by the skill.
http://pathofexile.gamepedia.com/Critical_strike_chance#Critical_Strike_Chance

The only exception to this I knew of was the curse Critical Weakness. Recently however I've seen things happen that let me assume me otherwise. It seems that Spectral Throw and Cyclone are rolling their critical strikes individually to each enemy they hit, ¿maybe because they are flagged as Attacks?

Since I am confused now I would like to hear your experience on that subject. I'll list some guiding questions especially I am interested in.

Usually all or none of the projectiles crit when you link Greater Multiple Projectile to it(with Fireball for exmaple), correct?
Does Spectral Throw crit on a per-monster basis?
Does the Second Form of Ice Spear crit on a per-monster basis if you link it with Multiple Projectiles since it is range-dependant?
Does Multistrike grant you a chance to crit to each individual attack for any Attack you link it with?
Do you know of any Gems or Supportgems which alter the critical strike chances to a per-monster basis ?

Thank you for your attention and have a nice day!

1. Spectral Throw -> is a cast crit -> all monsters that you hit crit.
1. Spectral Throw -> is not a cast crit -> all monsters that you hit don't crit.

3. Multistrike, no



for Ice Spear is a good question, if with the first cast you hit and crit 3 mobs, the 3 mobs are frozen. Now the second cast hit the 3 first (and frozen mobs) + 2 new and not frozen mobs.

the response is, i don't know.

I think cyclone is on a crit per attack, not a crit per use of skill. I don't know about spectral throw though, not very familiar with it.

I wouldn't be surprised if it were a crit per hit. Other wise, when you threw it out and saw a freeze crit, you could leap slam behind a bunch of enemies knowing that they'd all get crit on the weapon return component.

Needs testing.

for cyclone, if i don't crit on the first attack / spinning series, the second (with multistrike) never crit.

Specral Trow and Reave crit on per attack basis - speaking from experience here. Especially Reave - so much fun with good ele damage and Elemental Proliferation! :)

All spells/abilities roll for critical only once - and then this roll is applied against each monster hit individually. Therefore it is possible to score a normal hit against one monster, a critical hit against second monster cursed by critical weakness and a normal hit against 3rd monster cursed with crit weakness, but against whom you failed to confirm the critical.

Cast on crit triggers on each target hit which will probably get nerfed to be once per spell, making it useless skill gem.

When you perform action (attack spell w/e) crit is rolled .
I quess it would work like this:
-Roll 1-100, then add your current critical strike chance, save the variable for all effect of this action.
-When action connects apply modifiers from that target like +critical strike from critical weakness but possibly also reduce the value if mod "resistant against critical strikes" would be added to game.
-check it against 100, if equal or more then apply critical strike mult.

The only player ability that rolls twice is infernal blow because it uses separate crit chance for the explosion.

Thank you all for your sharing of experiences especially azmodael with his pos which clarifies my doubts about the per-action based skills.

I can explain recent skill interactions now which I've recently seen ingame.

Also a special thanks to Stt3r0 for his insight:

That would indicate that the Second From of Ice Spear would work similar to Critical Weakness and therefor allow multiple critical strikes per cast do you agree ?

Please continue sharing your thoughts on this topic!

It goes like this - you cast Ice Spear - game assigns you roll for crit of 23

Your base crit chance on Ice Spear is 7%. You have 200% increased crit from passive and gear bringing that crit chance to 21%


You hit a monster that is close to you with first form - 23 is more then 21 therefore you do not crit, but the ice spear pierces that mob and continues to hit another mob, but now it's in it's second form that adds another 600% bringing that crit chance to 63%

63>23 therefore you crit the mob and the spear detonates freezing it.

If you had GMP/LMP this same check would be applied to every monster therefore you wouldn't crit any of them with the first phase and crit all with second phase.

If this was an attack it would be a bit different - you'd attempts an accuracy roll on each individual mob hit with a critical threat - and if the accuracy check passes you'd crit or not crit them individually.

Thank you a lot azmodael for making it clear to me how its going to be calculated.

And I think all my questions are now answered.The only thing which bugs my mind is why the curse Critical Weakness is treated differently.

Nevertheless thank you all for your insight.
