How does Shaper of Winter Work?

I'm trying to work on a Cold DoT elementalist build, and I'm trying to figure out how Shaper of Winter works.

"

All Damage with Hits can Chill
Chills from your Hits always reduce Action Speed by at least 15%
50% more Effect of Cold Ailments you inflict with Hits for which the highest Damage Type is Cold
Your Chills can reduce Action Speed by up to a maximum of 40%

How exactly does this work?

For example, if I say do 100 cold damage with freezing pulse against a T16 rare mob, does the cold ailment bonuses apply before or after the 15% minimum?

Also, how do baked in chills work? Creeping frost has a ground targeted chill, and Wintertide has a chill attached to it. Does Shaper of Winter not work at all because its not a "chill from your Hits"?

If not, the node seems pretty weak and I dont really understand how you're supposed to use it.

Your not necceraly ment to sue it with cold damage, you use it to allow all of your other damage types to chill so you can make use of stuff like Hypotermia Support without having to have a seperate source of chill.

That doesn't help at all. Most of the skills that are cold DoTs have some form of built in chill effect already so chilling the enemy isn't the goal here. Its trying to figure out if I can leverage the Chill effect to increase other skills through bonechill.

It should be applied before so you are not going to be getting 22.5% minimum chill.

Other than the last line, you can say pretty much it does not boost baked-in chills.

Skills like Vortex still has a hit component to it, which gets boosted by this new ascendancy notable, inflicting a bigger chill which then synergizes with Bonechill to deal more cold DoT.

I still don't know if I understand how this works. How is the chance to chill calculated if my char has "Shaper of Winter" but my hits do no cold damage?

All damage can chill means your hit with any damage type qualify for the chill mechanics

Chill chance doesn't exist, you chill every hit if you do sufficient damage to apply one, obviously by default only cold does this.

the more cold ailment is applied after, so yes if you do cold damage as your highest damage type and hit for at least 1 damage you will apply a 22.5% chill.

Creeping frost has a hit associated with it and will provide the larger chill from hit characteristics until the duration of that one expires at which point the ground one will take over which I'm fairly sure doesn't receive the 50% more cold effect multiplier.

Wintertide gets zip except 40% maximum chill effect instead of 30

The nodes pretty strong as chill is a superb defensive mechanism and it acts as a damage multiplier for cold builds because if you have a greater chill, you have greater bonechill amplify too. Even if your primary damage source was wintertide brand it would still give you a major boost if you run vortex + bonechill in parallel.

Think I covered them all there without ballsing anything up :p

@Draegnarrr Thanks a lot! That explanation helps.

Followup question. Let's assume I'm playing a lightning build with no added cold damage to spells included, but high crit/shock chance.

Will including shaper of winter make my chill = shock at same time?

Shaper of Winter will make it so 100% of your hit (physical + elemental + chaos) is applied to the amount chilled. If the total damage is > 4.93% of the ailment threshold then you will apply a chill equivilant to the damage dealt (base chill is > 15%). If you do less than 4.93% (even 1 measly damage) then it will default to the minimum 15%. Whatever the base is is then multiplied by your increased chill effect. If thehithad more cold damage than any other source, then it is further given 50% more effect.

Now if you were going with an Arc build and doing 100% lightning damage, then you would get everything except the 50% more chill effect. The lightning damage would still apply shock as normal, calculating only the lightning damage portion and require a minimum .32% ailment threshold.

And before you ask, everyone who knows the specific ailment threshold for bosses is under contractual obligation to not tell you. Most mobs are 1 to 1 life to threshold. I can't remember with rares. Uniques (at least high end bosses) have a lower the threshold than hp.

Thanks that was exactly the info i was looking for clarification on. Perfect!
