Halsin speed chance

[LostSoul]

I looked around a bit and didn't find an exact answer for it outright, but what is the first-kill trigger chance in a regular area for Halsin with a max-level slot 4? I mean, obviously, the 'max' chance goes well above 100%, but I'm curious what the 'minimum' chance is to trigger on the first kill of an area with unmodified completion requirements (which is defeat/collect 25 whatevers).

Max level is 32571 with epic with a base 100%, so the max buff from gear is 1+32570×0.04 = 13128%

Base chance of ability is 20%, I think.
So with that gear: 0.2×(1+131.28) = 2645.6%
Then you can get three feats (20, 40 & 80%) and the 50% boost from Vow of Harmony, all are multiplicative. So 26.456×1.2×1.4×1.8×1.5 = 120 max chance at one away (=12000%).

Sadly, I can't go farther for now as the ability is temporary disabled until they fix it. I can't compare to my gear value nor figure the curve of the skill and its formula.

It appears to be enabled again. So, from what I've observed so far -- the 'chance' to trigger on the first 'progress' tick in a standard 25-completion area, with a non-shiny epic at ilvl 1200, is ~1%. That was ~30% improvement over ilvl ~600, or about 0.3% additive increase per 600 ilvls. That puts the final tally at around 16% to trigger from the first progress tick. That's with all 3 feats. Furthermore, swapping Hewmaan for Sentry (for a 30% area reduction) boosted Halsin's initial trigger chance to 2.1% which, if the previous pattern holds, would mean a 32-33% chance to trigger on a single kill?

Not even remotely impressive, all things considered (and the 160k total ilvls it takes to get there). And his effective trigger chance does not appear to go above 100%, so he can't multi-skip either.

Okay from the numbers I see, the base chance is then:
[Ability chance]/[current missing objective]^2
Capped at 100% of course

So the answer is, at item cap and with 7+ vow of harmony stacks:
120/25^2 = 120/625 = 19.2%

And for a more in depth exploration:
At 25: 120/25^2 = 120/625 = 19.2%, so 19.2% chance to have proc
At 24: 120/24^2 = 120/576 = 20.83%, so 36.03% chance to have proc
At 23: 120/23^2 = 120/529 = 22.68%, so 50.54% chance to have proc
At 22: 120/22^2 = 120/484 = 24.79%, so 62.81% chance to have proc
At 21: 120/21^2 = 120/441 = 27.21%, so 72.92% chance to have proc
At 20: 120/20^2 = 120/400 = 30%, so 81.04% chance to have proc
At 19: 120/19^2 = 120/361 = 33.24%, so 87.34% chance to have proc
At 18: 120/18^2 = 120/324 = 37.04%, so 92.03% chance to have proc
At 17: 120/17^2 = 120/289 = 41.52%, so 95.34% chance to have proc
At 16: 120/16^2 = 120/256 = 46.88%, so 97.52% chance to have proc
At 15: 120/15^2 = 120/225 = 53.33%, so 98.85% chance to have proc
At 14: 120/14^2 = 120/196 = 61.22%, so 99.55% chance to have proc
At 13: 120/13^2 = 120/169 = 71.01%, so 99.87% chance to have proc
At 12: 120/12^2 = 120/144 = 83.33%, so 99.98% chance to have proc
At 11: 120/11^2 = 120/121 = 99.17%, so 99.9998% chance to have proc
At 10: 120/10^2 = 120/100 > 100%, so 100% chance to have proc

Things are better with Sentry, as it starts at 17, so 41.52% and reach the cap at 10 quest items required too. Cumulative chances are with Sentry: 17: 41.52% / 16: 68.93% / 15: 85.50% / 14: 94.38% / 13: 98.37% / 12: 99.73% / 11: 99.998%

But clearly not very impressive anyway for the huge investment, but the good point is it will be a killer buffer probably at that amount of gear in a good (neutral) party, due to emerald grove buff (and probably AA with potential Ceremorphosis +3).

That's kinda where I was putting him as a speed champion -- in the 'meh' tier for most things, in a similar boat with Lae'zel. I mean, I guess, if you've already got 9j Briv, why not? He's at least a decent support champion, so not a complete loss.

Speed usefulness aside, I question the decision to put him in a slot that already has an AA member, and already has 2 Ceremorphosis champions., and 3 speed champions. Do they eat Crayons at CNE?

I believe the datamined info was that at absolute hardcap of the effect it would be a 100% chance to trigger at 10 progress remaining (that being the kill that moved it to 10 progress).

It was intentional, since "you can't get both Minthara and Halsin in your party at the same time in BG3". That said, Halsin's numbers are worse in almost every regard.

IIRC, actually you can, but it takes quite a lot of hula hoop jumps.

Let's say you aren't intended to get both in your party then. At the very least that's what I've heard.
On an unrelated note, you can field both Halsin and Minthara at the same time here, similarly using a bug/exploit, which is pretty ironic.
