then ririmu kept on reading there are four type of ADC in game its easy to understand for begginer and advanced players and ririmu will discover an adc that maybe suit her or understand about adc position reading there is hyper carries they low mobility low wave clear fragile early game theres that high item dependency but they scale really good its like champinos like jinx vayne kog maw aphelios they are hyper carry theres also skill adc casters they are stronger early game they have strong skill set they can pressure they build lots of AD instead of critical strike chance and then ririmu she wonder what a critical hit is she ask us...wait, what's an critical hit even? she trying to grasp about the concept what AD is versus what critical strike chance is now she chatting with soma kun its her little 6 years old baby but yea there is soma-kun he also good league teacher she called teacher so she can learn more ririmu sharing the screen and soma ask how it going the study and ririmu said its fun and soma said its fun thats good its super important and ririm usaid hmm what was it that she got lost with ah she was reading about this "instead ofbuilding items that increase critical strike chance, they get items that increase their AD" this is a part that ririmu didnt get she dont understand so she ask soma to explain and he ask if ririmu if she knows what critical strike chance is, like jhin and well he ask what champion ririmu play with what adc and ririmu said miss fortune yunara and jinx and the ADC with the violin and soma laugh because there is no ADC with a violin so yea with jinx you build infinitiy edge it give you 25 % critical strike chance when you build your attack have 25 % chance of being strong! super strong and ririmu say woaahh and soma say its a stat it has and ririmu ask if its means its 25 % of luck and soma said yes ADC stack two or three items like that they get 75% or 100% and that make their attacks stronger and ririmu said ohhh hcritical strike chance yea that the build that increase critical strike like phantom dancer or infinity edge are crit items and ririmu then asks what AD is and soma said AD is well infinity edge has AD on it it ake your attacks stronger then ririmu ask if its the same then soma said a critical doubles damage of normal attack and AD increase the base value that gets doubled
