Kai'Sa is a marksman-mage who chains Plasma effects: each attack applies stacks, and her allies' immobilizing effects add some too. Her items upgrade her basic abilities (Living Weapon), which changes her playstyle depending on her build. Her ultimate dashes her to an enemy champion, ideal for an execution.
