It still makes me laugh when an enemy AP rushes Luden's Echo then asks me in all chat how I 1v1'd them when my items are pretty much mana regen and maybe half an Hourglass. Nice 120 AP item, be a shame if I had an ult that takes 80% of your combined AP then slaps you across the face with it... The legitimate oneshots lategame still surprises me. Flash R on a full health Cassiopeia and she just dies.
"/all Outplayed"
As someone who mains a Mythic Cassiopeia ... I can confirm this is extremely true to the point it makes me cringe.
19 kills and 4 deaths, I am acing it with my girl in mid lane. Getting all of those kills, helping others survive their lanes by surprise assaults, and even wrecking the dragon when jungler is to busy farming elsewhere. Suddenly, a god dang 12 kills and 7 deaths Rengar does his ult and kills me at FULL HEALTH, one shot kill.
My disbelief and frustration still carries to this day when remembering a few champions being able to kill me in one hit, specifically if their build + abilities allow it. Luckily most are to scared in engaging a strong Cassiopeia player because being paralyzed for 3 seconds while being poisoned + spammed with fang strikes that deals insane damage with no CD is ... horrifying. It's actually advised in most guides to NOT solo a late game Cassiopeia because she can wreck in 1v1. In ganks, she isn't as tough unless fed.
