How to play as Zaahen
When Gwen activates Hallowed Mist(W), don't throw Dreaded Return(W) from outside it; either dash inside with Aureate Rush(E) before casting or wait for the mist to end.
Sidestep the center of Snip Snip!(Q), where Gwen deals true damage, rather than taking the full scissors combo.
Gwen's Hallowed Mist(W) prevents enemies outside it from targeting her with spells, so Zaahen's Dreaded Return(W) will not connect from beyond the mist.
