Critical Weakness is additive with base crit and is scaled by all crit modifiers
I saw some comments claiming that critical Weakness (the debuff from Eye of Winter, Malice, and Sandstorm Visage), is additive with total crit not base crit.
Critical Weakness tooltip: "Critical Weakness causes hits against affected targets to have +0.5% to Critical Hit Chance, and can stack up to 20 times"
For example:
You have 10% base critical hit chance and 400% increased critical hit chance. Your total crit chance is 50%.
A full 20 stacks of critical weakness gives +10% to Critical Hit Chance
This does not mean it adds 10% to your current total of 50% It does add 10% to your base crit. Now that you have a total of 20% base crit, your total crit is now 100%.

Here's the setup for the test
10% base crit staff with roughly 400% increased critical hit chance. My total crit is just above 50%. I have no additional base crit from any sources (I'm not taking the 1% node).
I mark the enemy with Sniper's Mark, which is consumed on crit. I show that sometimes when I hit, I don't consume Sniper's Mark.
Then I put on Sandstorm Visage and wait for full stacks of critical weakness on the enemy.
I mark and then hit the enemy 30 times in a row. The mark is consumed every single time.
At the end of the video, I take off Sandstorm Visage, let critical weakness fade, and do it again. Like in the beginning, sometimes my hits fail to consume Sniper's Mark
The chance of critting 30 times in a row with 60% crit chance would be about 1 in 4 million.
Let me know if there's something wrong with how I tested this and if you have proof that I'm wrong.
TLDR: Critical Weakness is strong and works just like brittle from poe1
Comments
known information but good info for new player.
Too bad that that the malice scepter rolls with scepter mods
Is there a way to get critical wakness as melee besides Frozen Orb?
Yeah, critical weakness is amazing and the main reason lots of builds run a eye of winter utility setup.
So far we only have 3 sources, Eye of Winter, Malice on the Sceptre and Sandstorm Visage.
One note about Sandstorm Visage. The Crit weakness only falls of if enemies leave your presence so it always stacks up to max in 10 seconds and is not bound by duration like Malice l.
This seems too good, for any crit based build that's nearly going to double your crit chance. I'd expect this to be nerfed. If you're bloodmage that would mean you have basically 25% base crit on every spell
Yeah I use an eye of winter to pop my bell and it’s so good because it also applies the debuff.
Wait…
What about what about the +10% to critical hit chance nodes in crit clusters? Is that +10% to base or 10% overall? Same with the bonus on the helm… and Quiver? Right now I have like +94% to critical hit chance… please don’t tell me that’s like base 5-10% X 1.94… that’s garbage 🤯
Well I know what I need to check now… Well it makes sense why it wasn’t increasing DPS by as much as it should.
