Hewwo everyone and welcome to my build! Read below to find out about the runes, the most important part of this build. I'm not going to explain how Zoe works in general, because this probably shouldn't be your first build on her. If you've played Zoe before, though, feel free to try this out :3 And leave me some feedback while you're at it!

GLACIAL AUGMENT: This is the core of this build. This rune is what'll be winning you games. Here's why it's good:
1. Your passive - autoattacks. Glacial Augment procs with auto attacks. It's that simple
2. The slows are great to help you hit someone. Imagine landing a close-ranged E. You can instantly use your animation-less autoattack from your passive to prevent them from getting too far. Same goes with attacking someone after you land a Q to set them up for another one. It's prefect for when someone's running away from you.
3. It procs with stolen items! For example this build gives you a better chance against Katarina than normal Zoe, because you can use the freeze ray every time she uses gunblade. Same for other champions that build slowing items, such as GLP.
4. It's fun. That's all that matters, r-right?

PERFECT TIMING: I take this rune even if I'm playing with Comet as my keystone. It's just a must-have against all assassins, so you'll be using it in every game if you're low elo like me. If you're confident that you don't need it, the second best option is Biscuit Delivery.

FUTURE'S MARKET: It adds to the cheese a lot. You'll be having important items way earlier and you'll always have enough for a control ward when you get back. Second best option is Magical Footwear, although there's no reason not to just pick this one in every scenario.

APPROACH VELOCITY: You'll be able to cast better long-range Qs on sleepy enemies without using your ult. Not much more to say here. Although if you don't like the appeal of this, take Cosmic Insight instead. Don't take Celestial Body because you need more poke damage, and the health isn't worth it, unless you're gonna be hugging the turret early game anyway (for example against a Zed)

MANAFLOW BAND: It's just the best of the first 3 options, and you don't need anything from the second 3 anyway. I used to think Ultimate Hat is nice because you can max it out quickly, but you don't really need your ultimate often enough for that one or two extra seconds to make a difference. If you're up against a magic damage heavy assassin, consider Nullifying Orb, duh

SCORCH: Helps with the poke, that's all. If you're going to need to go against this champion's nature and play safe, take Gathering Storm in order to have a bit of a late game advantage, although playing Zoe safe is not a good choice, especially with this build, unless you first pick and end up matched against a Zed (in which case you should probably take a normal rune build and take Gathering storm there.
