Experiment 177 Skill Critical Rate on Yul follow-up

Goal: to follow-up on the DEX experiment and discover how different Skill Critical Rate buffs and items sum up together.

As a follow-up to the previous DEX experiment, Skill Critical Rate of Yul Archer was tested with different sets of buffs and items. It was assumed that effects increasing Skill Critical Rate simply get multiplied by base Skill Critical Rate (which is determined by DEX). Here’s a table with few setups:


To keep the post clear and informative, the table contains only few chosen setups that clearly show the tendency, cases where expected change is small were tested but not shown in this table.

List of gear tested:

Conclusion: the experiment has confirmed what was long suspected - multiple effects increasing Skill Critical Rate are multiplied by each other and applied to the base Skill Critical Rate. In fact, most of the buffs in the game work this way.

Example:
If you have 20% base Skill Critical Rate, and add https://l2wiki.com/Superior_Critical_Arrow_-_Yul_Moonlight_Sentinel and https://l2wiki.com/Prophecy_of_Might_-_Iss_Hierophant and https://l2wiki.com/Hunting_Instinct_-_Yul_Moonlight_Sentinel then the Rate is calculated the following way:

Skill Critical Rate = 0.20 (DEX) * 1.1 (SCA) * 1.25 (PoM) * 1.15 (HI) = 0.31625 => 31.625%

To help you with your builds, the calculator has been extended with the results of this experiment. This is how it looks like:

Spoiler

Any inaccuracies come from the DEX experiment's base Skill Critical Rate which had a statistical error.

 

But but... since day one, all pr0 yuls were adding +15 STR dyes.


*ps: Could you do some test with mages, DPS differences between lets say:m.skill power,m.skill power crit.dmg/rate, m.attack
The reason is: Which is the best ISS for a mage: PP, WC or EE ?

 

And that's an OK choice, gives a lot of damage but you crit less often, while with +15 DEX Dyes you crit more often but for less damage.

That kind of test is too much gear-dependent -> meaning results are different depending on a gear, 1 item can change everything. It's well-known that multiplying M.Atk by 4 increases damage twice (since Battle Rhapsody gives more than that), M Crit Rate is locked at 30% (it's unknown if PoM bypasses that), M Crit Damage scales by all items that give M Crit Damage, and M Skill Power simply increases the power of skill you use.

 

Spoiler

oly talisman of battle 20% SCR

and item argument +15% SCR

 

It's not possible to test it outside Olympiad/CoC, but since all the items work the same, it should work the same too, so x1.2

1. Nobody uses that when there's Skill Critical Damage
2. Works the same

I'll add them to the calculator regardless

 

Here we miss an important thing about critial rate. Skill enchantment. Could you add the possibility to set the skill critical rate enchant on your site? Allowing to add the value step by step (1,2,3,4,....).
Btw ty, this is what I was waiting from L2 to know since I started to play.
On the other side will be good to se the damage lost if choose skill critical rate instead of damage (with kain, leona, augment, skill enchant on brake or power). This will allow ppl to know every "secret" of yuls and all the pro and cons of their choice.

 

Done

 

Many thanks!

Now the yuls archive miss the info about the same gain turned to power.
STR dyes
skill: break/power enchant
SA: skill damage
AUGMENT: skill damage
etc

and maybe the actual STR affecting skill reset which has been enormously nerfed by changing the passive 1000% STR to 100%.
I mean is useful to boost STR for skill reset? For the same reason is still good boost skill mastery on AP? How much it affect skill reset?

What you guys think about this kind of experiment?

Btw ty Palkah and take your time; I think your list is already full of test request.

 

Something is wrong with the calculator, my stats are:



and after 480 hits on a town NPC, I had 343 criticals so 71.45% crit rate.
If I'm not wrong, focus skill enchant is added as a flat percentage on the base critical rate and obviously gets boosted by all the bonuses.

 

I'll check that once I get access to the PTS, BUT town NPCs are not good targets. Why? Go to a low level location (like Wall of Argos), and hit mobs with skills/autoattacks. You will notice you crit 100% or at least many more times than on regular targets. This could mean one of two things.

1. If you greatly outlevel your enemy, your crit rate against him increases
2. Each level difference gives you more skill crit rate

That's why for a proper test you need to hit a target with same level as you. NPCs level can be much lower than yours and make the test invalid.

I'm not saying you are wrong, I'll check that tomorrow, but your test could be wrong even when you are right Also I calculated and if you are right you should have 55% rate so 70 sounds too high, at least 10% too high. That probably confirms the level issue

 

Yeah it's probably what you say about npcs and level difference, but I'm pretty sure focus skill enchant is added as flat percentage on base critical rate. Waiting your testing for confirmation .

 

I have told Palkah the same already.
Playing archer for a long time the % shown is definitely not correct. There is some stuff missing which is boosting crit rate a lot.
In PVP I had close to 80% crit rate without any active skill. (only 30 mins buffs+pom)
(Obv. I couldnt really count the amount of crits but I can see the huge difference compared to 30% written here)

 

There is either an effect we all overlooked, or there is an item that gives hidden Skill Critical Rate then, or it's just your feeling, or DEX scales better (I gave a margin of +-5% after all), since these results were as predicted for 80 and 110 DEX

 

In one thing se must agree. Korean manage "The Matrix".

Just check how really work skill focus enchantment and I think it's done. I agree with results compared to gameplay.

Hax do you have great emerald? It boost critical rate about 30% too if I remember well last pvp server I've been

 

No its skill mastery https://l2wiki.com/Greater_Emerald

 

definitely not my feeling. I was nearly always sure my hit will crit and I could rely on it really well.
There is smth you have overlooked for sure.

Nop no emerald

 

What was your DEX? Also you're overlooking that the update changed, could be some ninja since archers got a lot of changes.

 

at some point 101 dex, but you can count 94 or so for most of the time.
As I said, I was critting extremely reliably. With the active skills i had a 100% crit rate or close to it for sure.

 

I've finally got my PTS access back and retested everything for high values of DEX (110), with 1000 hits in each scenario:

With 110 DEX + passive I got ~38% crit rate
With 110 DEX + passive + 10% AP Skill Crit Rate I got 42.6%
With 110 DEX + passive + 10% AP + PoM I got 53.6%
All of the above are well within the statistical error so no red alerts there

So then I thought "hey, maybe you were testing with Pinpoint, so I'll try that one too. maybe it has some extra bonus for rate". Took me ages with that one due to high cooldown.
With 110 DEX + passive + Pinpoint Shot instead I got 39.2% Skill Crit Rate, so within the error margin too, meaning it has no extra bonus

So lastly I checked the Focus +20 on Quick Shot:
With 110 DEX + passive + Quick Shot +20 Focus I got 47%. Which means that enchant bonus is multiplying everything instead of being added to base SCR, exactly as I said before.
Again, within margin of error.

So:
1. My tests were correct
2. I've rechecked every item, buff, and passive I had to make sure the results presented are for the items I claim they are.
3. Your different values are due to one or some of these:
a) level difference between characters
b) low number of hits (keep in mind that after retest some data points were confirmed with 1500 hits already)
c) you have an effect which you forget about while testing (AP, some SA) which adds to your value of SCR
d) invalid way of counting the crits
e) the way this game's RNG system works
f) using a skill enchanted to ++Focus without noticing it
g) having an item/buff that has a hidden effect of extra SCR
h) using skills that get reset via Skill Mastery, or multiple skills instead of one***
i) some other factor we are unaware of that gets eliminated in my test environment but not on Live

*** - I've noticed that if you perform actions in a small timeframe (so casting a skill two-three times with Skill Mastery, or two separate skills one after another) they often get the same RNG result, meaning they both crit etc. This happens due to RNG seed not 'resetting' fast enough, assuming it's even based on time.


That's all I can think of.

 

Basicly with other stuff, is possible to go 100% crit rate?
