A bit confused by something regarding expertise. I’ll use polearm expertise as my example.
When Using a polearm:
-15.00% increased Lucky Hit Chance
-You deal 15.00% increased damage while healthy
Does this mean I get the 15.00% increased damage while healthy by simply wielding a polearm? Like do all my attacks get this 15.00% increase if I have a polearm equipped or does it only apply to skills that attack with the polearm?
Open up the weapons expertise UI. Select polearm. Then hover your mouse over the big circle on the left-hand side of the UI labeled Technique and it tells you what effect is applied to ALL attacks (lucky hit in this case).
The 15% damage portion would only apply to skills that actually use the polearm.
Yes you skill must use Polearm in order to get the both bonuses. Certain skill allows specific Arsenal weapon to be use. Skills like Steel Grasp can NOT use Arsenal weapons so they don’t gain any bonuses.
If you select Polearm as the Arsenal weapon, you gain both bonuses. If you select Polearm technique, you only gain the top bonus, “+15% Lucky Hit.” If you already selected Polearm as an Arsenal weapon, it’s pointless to use Polearm technique since they don’t stack.
Console player here but thank you very much for your help, you answered exactly what I needed to know!
would you happen to know how the 15%× lucky bonus from polearm is applied mathematically?
Lucky Hit works like this:
Base Lucky Hit% x (100% + Lucky Hit Chance) = Actual Chance to Proc
If your Skill has a 50% Base Lucky Hit Chance, the 15% Polearm contribution looks like this:
50% x (100% + 15%) = 57.5% Proc Chance
If you have an additional 35% Lucky Hit Chance from items:
50% x (100% + 35% + 15%) = 75% Proc Chance
Lucky Hit Chance contributions are Additive, which is a good thing. There is no cap to Lucky Hit so exceeding 100% chance will still benefit the Proc Chance from rolling.
Keep in mind the other part to this formula is the actual Lucky Hit % Chance of the actual Proc stated on the Tool Tip. So if that is a 50% chance to Stun enemies given the two examples above:
50% x (100% + 15%) = 57.5% Proc Chance
Or
50% x (100% + 35% + 15%) = 75% Proc Chance
If you had a 100% Lucky Hit Chance, this gives you a 50% Chance to Stun enemies everytime the Skill is used.
If you had a 200% Lucky Hit Chance, this gives you a 100% Chance to Stun enemies everytime the Skill is used.
What this means is that with enough Lucky Hit Chance, you can overcome fairly low coefficients as with items like FoF, Polearm, and GA Lucky Hit Masterworked, you can get pretty high Lucky Hit. There are more detailed guides on this.
so if you’re trying to make mobs vuln from an affix on gear for example
Lucky Hit: up to 62% chance to make enemies vulnerable
then that would be
50% x (100% + 35% + 15%) x 62% = 46.5% chance to make mobs vuln right?
Yes, that Skill would have a 46.5% Chance to make enemies Vulnerable in that example.
If the Skill is a DoT, it gives you the 46.5% Chance over the entire Duration which sucks. Anything that extends the duration of the DoT I would assume would basically nerf your Lucky Hit chance.
The in-depth Guide on Maxroll also will tell you the hidden stuff going on like how procs of procs work (they mostly do not) and some AoE variants of Skills.
Ty i <3 carrotfeets!
You’re welcome, it would be nice if D4 was more intuitive and transparent!
rofl that’s what im saying maybe some type of genius librarian guide npc like a chatgpt to help us understand d4 clearly
