Upon evolving Kai'Sa's basic abilities,

grants invisibility for 0.5 seconds.
Kai'Sa
W
grants True Sight of the struck enemy.
Kai'Sa
E
's cooldown is reduced by 0.5 seconds per auto attack.
Kai'Sa
R
is an extremely fast dash, but can still be interrupted.
Strengths
Has strong 1v1 potential since
Kai'Sa
Q
will fire all its missiles at one target.
Excels at poking from a safe distance, especially before teamfights. This is especially true when
Kai'Sa
W
is upgraded.
Functions well as a follow-up diver with
Kai'Sa
R
with her high damage. Also doubles as an escape tool.
For AD, Best with items enhancing attack damage, critical strike, and attack speed.
For AP, Best with ability power-focused items for burst damage and enhanced abilities.
Weaknesses
Very reliant on gold and levels.
Kai'Sa
E
prevents her from auto attacking during its cast, which can be harmful before evolving it.
Once
Kai'Sa
R
is used, Kai'Sa has no way out of a fight.
