Overview
zetian is a poking mage, but she can have a big damage based on the build.
Strengths
early game she was very weak, but if you understand the pasive she can control the early to mid game. at the late game she have more damage, but she was easy to ganked.
Weaknesses
mobility, zetian needs Flicker or purify to have a escape skill because her pasive just give her a knockback to enemy.
damage
at lategame you can changes bloodwings to imortality or winter crown.
idk
zetian is a mage that have a long cooldown ultimate, so you can use cooldown reduction for her i guess
Battle Spell
zetian mostly use Flicker but if the enemy Hero have so much CC you can use purify
best rotation for zetian
after cleared the mid Lane wave, you can go to goldlane for help teammates but you should go with ur roamer, so you don't get ganked.
Best With Zhuxin
zuxhin have a CC that can make zetian get presured
Watch Out For Kadita
you can use purify to deal Kadita, but she always at the bushes so you night get killed if you don't aware
