Fun Trying to Exploit Crits

Statick··2 votes·1,463 views

So I read a lot and found that League of Legends uses a pseudo random system for crit chance. Basically if your first Auto doesn't crit then you next Auto has a higher chance to crit and vice versa. This is to stop for example someone with 20% crit chance getting 6 really lucky crits and winning any fight, or someone with 80% crit chance getting really unlucky and gets no crits. If anyone could post the exact algorithm I would be super happy

Now the obvious exploit is hitting minions until you get a no-crit spree and start a fight. Idea being is now your crit chance is higher than what the game tells you. Although I hear the difference is pretty negligible

Another Idea I had involves cancelling auto's. If you see your champions crit animation, then cancel that auto. Are you guaranteed a crit on your next Auto. depends when the system checks the Auto for a crit. More likely not and you get the lowered crit chance on your next Auto.

It makes me envision a script that attacks and cancels Auto Attacks rapidly watching for crit animations or something, and stops when it gets your actual Crit chance to a certain higher percentage. Although with a script like that you would be better of making it cancel all non-crit Auto Attacks and make it redo the auto until It gets a crit. Cancelling Auto's does not put your Auto on cooldown, so this could be done quickly -For example you have Infin Edge and Phantom Dancer = 50% crit chance You would be cancelling 1 out of 2 Autos, but would critting 100% of the time (for 250% dmg with I.E.) Lets say it takes 0.2 seconds to check an auto for a crit. You would get 75% more dmg and lose 0.1 seconds on each Auto. #WORTH (Although this would be blatant cheating and would not work with stutter stepping)

A combination of both Ideas would be crazy. Certain champions have really obvious crit animations and are easy to cancel Auto's on, so it makes me wonder if someone with a lot of practice could do it, without scripts. -This guy has scripting like movement on Kog'maw without them. https://www.reddit.com/r/leagueoflegends/comments/4445i8/

  • This is all just speculation. Someone that knows more about this needs to check some of this for me.
  • I do not in any way like or support the use of scripts
  • There are many easier and better ways to be better at the game, this is all pretty useless, everyone knows

This appears to be a misunderstanding of what pseudo-random number generation means, so allow me to gift you some insight.

Computers use a mathematical equation to determine the next random number in an endless series of random numbers. The formula is designed to provide a model that approximates rolling dice as closely as we can manage. That is to say, if there is a 1/36 chance of rolling two sixes, then in the long run about one in 36 pairs of rolls will be two sixes.

There are many more measures of randomness, such as the distribution of length of runs of numbers that are each higher than the previous, how the numbers would plot in a multi-dimensional graph, and so on.

The difference between pseudo-random and random is that pseudo-random number sequences are entirely determined ahead of time by their seed, whereas there isn't enough information to say the same about random numbers.

Pretty sure there even is or was a script that cancels non-crit autos.

its interesting. the idea of "i havent crit in awhile IM BOUND TO CRIT" is just wrong. mathematically you are no more likely to crit on the 7th auto after having not crit 6 times in a row than before. its unlikely of course. probability says that. but your technical chances are the same they always have been. its why you can get 10 in a row without crit. and 5 in a row with crit with only 10% crit. i mean its highly unlikely but it can happen. every attack is individually generated. so your chances are not actually going up. there is no actual way to exploit the system even if it feels like it.

To set the stage for comprehension, let's roll **three ** six-sided dice looking for the outcome three sixes. totalChances = sidesPerDie ^ numDice = 6^3 = 216 chances. There is only one of those 216 possible outcomes that contains three sixes, and thus 1/216 chances of that outcome. So far, so good, right?

For Part Two, let's roll **two ** six-sided dice looking for the outcome two sixes. totalChances = sidesPerDie^numDice = 6^2 = 36 chances, and thus 1/36 of the outcomes will be both sixes.

And for Part Three, rolling **one ** six-sided die: totalChances = sidesPerDie^numDice = 6^1 = 6 chances, and thus 1/6 for the all-sixes option, completing the stage for the problem.

We know the chances at each of three points, the roll of a set of one, two and three dice. If we instead traverse the implied timeline forward from one roll to three it becomes a conditional probability problem, where the second roll comes with the precondition the first was a six, and the third comes with the prerequisite the first two were sixes.

When we take into account that our present state has been only one out of a set of many possible present states, we can then say on the one hand there is only 1/216 chance of three sixes and on the other at each stage the chance of the next roll being a six is 1/6.

except RNG in league isnt a six sided die. its a number generator that is random 0 to 100. if your number is at your crit chance or lower then you crit. if its higher you dont. it is random every time. your chances statistically do not increase. what increases is the probability. aka, its unlikely to get 20 straight tails when you flip a coin. but statistically speaking that 20th flip on a coin is still 50/50

IIRC, critical strikes are decided per target. If you cancel a critical strike on one target, then that does not guarantee you a critical strike on another target.

Tryndamere would be one of the simplest champions to test with this due to his innate critical strike chance and obvious crit animation.

God I hope this is right and I'm not really confused, but it sounds to me like you guys are just trying to tell me not to fall for the gambler's fallacy. That each Crit or roll of dice is 100% independent of the last. Which is very true NORMALLY. But as far as I have Heard LEAGUE OF LEGENDS actually uses a system that modifies your crit chance based on previous crits.

This is the video that sparked my thoughts on it all https://www.youtube.com/watch?v=C11MEnl2NYw - goto 1:48 he explains it

Also there is this http://forums.euw.leagueoflegends.com/board/showthread.php?t=1234132

Another forum that talks about it https://www.reddit.com/r/LeagueofLegendsMeta/comments/1cev8k/is_it_true_crit_chance_scales_up_for_every_attack/

I think the term "Pseudo Random" is used because of this system, not because its not 100%. Which nothing outside quantum mechanics are really.

Someone in the Lolwiki comments posted this

I have a question. With one single crit mark, how many autoattack will you go at maximum without getting a crit? I'm referring to this excellent table: http://prntscr.com/aevih1 Where the percentage is crit chance, and the number is maximum amount of attacks without a crit. How is this calculated?

(League has a pseudo crit thingy, so your chance of getting a crit after not crit ting keeps getting higher).

And then that was replied with this

=========================================== A maximum of 107 auto attacks. A crit mark gives you 0.93% chance to crit. Each auto attack that you don't crit increases your crit chance by that amount. The only auto-attack that is sure to crit is when you have 100% crit chance. 100/0.93 = 107.53, which means that the 108th auto attack will have 100% crit chance.

This is literally all I have found about the math behind it. As I stated if anyone finds more information about this I would be grateful because I'm super curious?
