Since Wikia has some "restrictions" her base Ki is at 175, it is called mana by her stat list. The reason for the 10% Health bonus on shield is because it is one of her strongest abilities at the moment, so I wanted to nerf all her base values, but want to keep something Viable with her. The 10% Health is also so people have a cushion for building tankier if they fall behind. Personally my two favorite defensive items in the game are Randuin's Omen and Spirit Visage, so I want to make them more viable items on someone who isn't a DoT, but a Burst.
