One Punch? One Lizard Crash Kled?
So I was messing around with Kled after I looked at the numbers on his ultimate. His ultimate deals: 12/16/18% + 12% per 100 AD of the target's max HP depending on how far you travel through your ultimate's duration.
Long story short I did all the math. Kled's AD Lv 18: 106 Runes: Full scaling AD runes +52 AD at Lv 18 Masteries: Doesn't matter just get Natural Talent and you're guuci +10 AD Items: x6 75 AD items (highest AD items in the game) +1 elixir +480 AD Infernal Drake x3 + Baron Buff + Elder Dragon 50% boost +40 AD and +36% AD
What this comes down to is: 106 + 52 + 10 + 480 + 40 = 688 x 36% = 247.68 (round up to 248) 688 + 248 = 936 AD total Now to put it into Kled's Ult: 936/100 = 9.36 x 12 = 112.32%
In the end you'll do 130% of your target's HP. However, sadly Kled's ultimate is affected by armor. So in theory if your target (the closest to/first champion you encounter when using your ultimate) had little to no armor you could one shot them.
