Blozzard’s chill seems to happen per dot tick.
Is this when lucky hit is rolled too? Or is it only on cast? Or has a chance throughout the dot to roll?

Edit: Seems im wrong
Lucky hit should only count on the initial hit if im not wrong similar to crit for bleed damage.
This is incorrect.
Any ticket of damage rolls lucky hit. Including damage over time.
Blizzard is damage over time. You can easily test this by enchanting fire bolt (apply burn when you deal direct damage.), cast blizzard, and observe the mob is not burning.
The tool tip lucky hit for blizzard is VERY high but that’s assuming the mob(s) will be in the blizzard for the full duration. So if a mob is running through your blizzard it’s not very good, but if you can get the mobs to stand still or kite them around in the blizzard it’s very good for procing lucky hit.
To help with this you can stack multiple blizzards on top of each other. They will combine their tick damage into a single tick - so multiple blizzards don’t increase the chances of lucky hits, but they do increase the damage and effect of chill each tick applies.
Sauce:
I run blizzard in my ice shards build instead of meteor, inferno, or deep freeze. Paired with the ice shards enchant, ot’s incredible at procing lucky hits against a screen full of mobs, applying stagger to bosses, or speed clearing aoe packs.

That makes sense and is similar to how hydras lucky chance works. It’s per cast, not per firebolt.
It was just confusing because it seems that blizzard broke their own rule when making blizzard chill per tick.
The way Lucky Hit works with DoTs is… All DoTs tick 2x per second. So if your DoT lasts for 10 seconds, it ticks 20 times. The total Lucky Hit shown for your Dot should be divided by the total ticks (20 in my example), and that gives you the Lucky Hit chance per tick.
I’ve read and heard elsewhere though that Blizzard will never Lucky Hit if you “floor cast” it; you must click on a target enemy to cast it. That sounds terrible - I mean what if the enemy you cast it on dies or moves away? Anyone know for sure how that works?
This is wrong, you cannot simply divide chance value.
The number in the description of Blizzard is a chance to trigger Lucky Hit at least once when all ticks (base duration) hit single target.
description_chance = 100 * (1 - (1 - 0.01 * per_tick_chance) ^ ticks_num)
Easy way to test the floor cast would be with Fists of Fate. Can a floor cast Blizzard apply the Lucky Hit Stun?
And if you do the division I said, that would be exactly correct.
If your LH chance is 20% and you do 20 ticks, the net chance of a LH for an enemy who takes every tick is 20%.
And each tick can trigger a LH. If it couldn’t, then the skills that increase the duration of Dots would be BAD.
You don’t seem to understand my previous post. Let me rephrase it.
Lucky Hit triggers on any suitable hit, that includes all Blizzard DoT ticks that hit something.
The number in the description of Blizzard is not a “true” Lucky Hit chance , nor it is some undefined “net chance”. It is exactly a chance to trigger Lucky Hit at least once when all ticks (base duration) hit single target. There are skill descriptions in the game data where you can find formulas for tooltip values.
And you cannot simply divide this value by number of ticks to get value of per-tick chance. For example, if description say 40% and you have 10 ticks, then per-tick chance is not 4%. This is nonsensical with respect to basic probability theory. I’ve provided a formula that relates chance from description, per-tick chance and number of ticks. You can rewrite it as (^ is an exponentiation operator; for “x ^ y”, “x” is the base and “y” is the power):
per_tick_chance = 100 * (1 - (1 - 0.01 * description_chance) ^ (1 / ticks_num))
For our example, description_chance = 40% and ticks_num = 10, then per_tick_chance = ~4.98%
