How Evasion works on POE 2?

also evasion is dependant on enemy accuracy, those percentages you see in stats tab are mostly wrong.

Go read up how evasion actually works, most of your assumptions are wrong

Evasion isn't calculated as a dice roll like most new players are assuming - the random dice roll to avoid taking damage is Block chance

Evasion is a weighted roll, and works off an "entropy" system for specifically HITS, meaning melee attacks, ranged attacks, and TARGETED spells

Evasion TL;DR: evasion isn't a random dice roll, it means that if you stand in front of something attacking you, it WILL EVENTUALLY hit you, guaranteed, but only so many attacks. 90% evasion, 1/10 attacks hits, give or take, depending on the monster. Not always accurate but a good rule of thumb.

That's why evasion cap is 95% and not 75% like block chance - 95% to avoid taking damage always is op AF and why lucky block was abused so hard in poe1 (rolling a block twice and taking the best result = ~92% chance to block which is insane)

This is why as an evasion character, the worst thing you can do is sit in a big group of mobs - taking 50 hits per second, you're GOING to be taking damage back to back to back as some of them break through the evasion entropy
you think they all only have a 5% chance to hit you, but in reality you're getting shredded

And like others said, evasion doesn't do anything at all for pretty much any AoE, no slams, no meteors etc. The best case scenario for you as an evasion character is to stay away from the AoE, go figure

As an energy shield/evasion mercenary using ghost shroud with ~20k evasion I've got a 90% evade chance and a floating pool of ~800 energy shield which Is never empty, literally the only time I die is to phys damage slams

Seems pretty balanced to me

This guy gave you the best breakdown of evasion you could possibly receive, so kudos to him, but here's a TL;DR:

Evasion has a pity system, like gacha games. 5% chance to hit you eventually becomes 100%. And that isn't calculated per enemy, that's calculated per dodged attack over time. If you bank only on evasion for survival, it's practically the worst layer of defense in the game. It's meant to be used in tandem with some other hard layer. (Armor or ES.)

So... Does anyone care to explain to me why I'm taking hits in a row?

because evasion is just evasion.. just another layer of defense. BaronArkas#2647 wrote a gg post that goes into more detail.

you need multiple layers of defense in poe to feel "tanky", not just one

It doesn't work with slams or AOE spells, which is at least 50% of the damage being thrown at you. If a mob comes up and attacks you (you can test this) evasion works fine. But most of teh time you are not letting them get that close. So it's a bit misleading.

i feel like this is weighted by your wrong perception of statistics?

"you think they all only have a 5% chance to hit you"


you seem to think that somehow equates to none of them will hit you. what that actually means is that statistically 1 in 20 of them will hit you, and what evasions entropy system does is guarantee you that you will get that perfect statistical outcome every time.

why would you think you would be fine taking 50 hits per second if they all have 5% chance to hit you? why would that mean you wouldnt get hit? thats not how probability works, you are just looking at the maths wrong. they do have 5% chance to hit you, and it will work out exactly every time that you do get hit by 5% of the attacks, guaranteed. i dont understand how thats not actually 5% chance to hit you, as if them REALLY having 5% chance to hit you would somehow mean they mathed out in practice to a 1% chance to hit you and all 50 would miss?


this whole way of thinking...

evasions entropy doesnt somehow rob you and make you eventually get hit. the fact you dont have 100% chance to evade attacks means you will eventually get hit, regardless of entropy being there or not. the entropy is purely a buff that stops you being unlucky and taking that 1 in 20 chance to get hit 3 times in a row cause woops you just rolled really really really bad this time.

that cant happen.




but the way you guys are talking is as if evasion should mean you never get hit but entropy fucks with you and makes you get hit and shredded. thats not what 50% chance to evade means, its not what 70% chance, 80%, or even 90% chance to evade means, none of those mean you never get hit. they mean you will get hit, thats not because of entropy, thats because you dont have 100% evasion.

if theyve kept the mechanics from poe1 consistent then all monsters at the same level have the same accuracy unless they are being affected by some kind of mod like a mapmod or an aura. so i think those tab numbers were using a monster of your level.

with armour it would be wildly different because there was wildly different physical hit damage depending on the mob type but with accuracy they all had the same accuracy so they char tab should be exact for monsters at your level and then higher than the number you are seeing if the mobs are below your level as a rule of thumb. so its a little easier to get a grip on from the tab than armour reduction.
