Qiyana, my look on her.
Qiyana is aiming to be the next difficult AD Assassin like Zed or Lee Sin.
That in itself is fine, but there's one thing holding her back from being... well, an assassin. Maybe you noticed, maybe you haven't. Her kit operates on auto-attacks mainly.
Now I've only played her for 7 or so matches, slowly changing the build I go ever so. Qiyana isn't a real AD assassin we all expected. She's a highly-mobile fighter. Her kill move is in her ult. If I had to say, her kit is similar to playing Renekton.
Now back to build speak.
Qiyana's auto attacks are powerful and massive in power.
This led me to taking these items:
Mobility alone covers up for her weak defenses, and Qiyana; though is supposed to focus on one champion at a time, is best against 2 or 3.
Ravenous' lifesteal and AoE damage helps her go from off-assassin to full on fighter. Healing and sustain during fights is a must on Qiyana.
That said, Death's Dance is self-explanatory.
Gage is mostly because unlike other assassins, Qiyana can single herself out during that small moment where her W is down. The only way she can disengage is with her W unless you can position yourself to E towards safety.
So, the shield and what not is critical for her.
I highly reccommend one defensive item aside from Gage.
Ideally,
or
. Both can be used amazingly in Qiyana's kit.
