Uh shit, guys, don't Double Ult with Yizuan.
The real power move is
Ult -> Auric Array -> Ult -> Auric Array

When you hold down te Dodge button (Auric Array) the game gives Yixuan 21 energy for free.
That's 42 perosonal energy if you temember to hold the dodge button after each Ult. That's crazy good.

Also, all the giant construction machines get utterly buttfucked by her Hold-Basic Inkball sphere, because they are big machines who can't move out of its way.
