Kei finally gets another patch, where I took another look at his damage scalings than his setup. Even then, some items were changed around. I'll be taking a look atPrimus's formatting to make my descriptions more precise and or correct by text.
 * Added items to trivia and skins.
 * His innate now deals damage based on current health than maximum health.
 * Most of Kei's abilities have received a reduction to their base values, mostly in the late game. In return, some but not all ability scalings and attack damage ratios have received a slight increase.
 * Sacred Barrier does not grant CC-resistance anymore.
 * Holy Blade has received some slight reduction to its range. It also scales off less AD for its inner-cone.
 * For Great Spirit, the magic damage ability ratio looked strong, so for the while, they've been reduced here and there. Talisman are applied less frequently and enemies are not "exorcised" for the duration of Great Spirit.
