Lets do the math here.
Xin Zhao ult has 75 base damage, 15% current health, and 100% BAD
Xin Zhao in this clip has 157 AD, and Xin Zhao's Base AD at level 8 is 83.3, so he has a bonus AD of 74.
The frame I take ult damage I have 747 health. So that would be an additional 112.
Xin Zhao has no lethality or armor pen, and his ult damage adds up to 256.
So, before resitances, I should have taken 256 damage, with 47 armor, I should have taken about 185~ish damage.
But I took OVER DOUBLE that?
Can someone explain that to me?
