Patch v1.01...includes some changes to Kei's kit along with some minor tweaks... And that is it...for Kei's first patch. Hope to tweak this concept around a bit more so he'll look more developed over time.
 * To start off, due to the bit of commenting in regards to overloaded kits, some of Kei's abilities have been minimized and moved around.
 * His passive now does not deal DoT. Thas has been swapped over to his ult.
 * His W does not have enemy cast anymore, but has received some buffs (and nerfs) to his abilities in compensation.
 * His ult, with the addition of the "Talisman" DoT, does not activate an auto-AoE of true damage on activation.
 * To be more concise, Kei has received some small statistical buffs too, such as health and damage.
 * His abilities have been scaled to more of a late game power, whether or not he's expected to be better late game. Some examples include the rescaling of the W's healing along with the increased duration of Great Spirit in later levels.
 * Few bits of lore and quotes have been added.
