Hey guys! I'm Hio102, a Silver 5 ADC/Mid main. I'm a Mastery level 7 Xayah. She's easily my favorite ADC right now, as her play style is so unique. I figured I might as well make a guide for anyone looking to pick Xayah up. I'll keep this updated as often as I can!

Xayah is best with the usual ADC spells, Flash and Heal.

If you have a Soraka or Nami with you, and are confident you can get by without heal, Ignite is also viable, but not recommended.

These are standard ADC runes. I prefer scaling MR to straight MR, because usually you won't need the early MR in the botlane. By the time you get out of laning phase, the scaling MR will have kicked in to a noticeable effect.

This is the biggest controversy of all the guides I've seen. Every guide has a different item selection recommendation. I have tested a few different builds with Xayah, and have settled down with this one.

Essence Reaver helps a ton with staying in lane longer, since you are a bit of a mana hog.

Berserker's Greaves is the best choice for boots, since you need the attack speed to get those feathers out fast.

I prefer Runaan's Hurricane as a second item, because of how useful it is csing and dealing spread out damage. You could also go Phantom Dancer to nullify unit collision, or Rapid Fire Cannon to get a little more range for basic attacks.

After Runaan's, Infinity Edge is my go-to. Combined with ER and RH, at this point you have plenty of damage no matter how far down you are.

The rest of your build depends on their team. Guardian's Angel is a safe bet against most teams, or Mercurial's Scepter.

Q, Q, and more Q. Maxing Q is now best, as you want to harass as much as you can early game.

After your Q, max E for the damage from feathers. It's also a useful escape if you land the root.

W is next and last.

Fervor is the best keystone for Xayah, since you at primarily focusing on auto attacks. Biscuit of Rejuv. helps a ton with keeping a little mana in the tank for some last hits on their adc before you recall.

So what's so good about Xayah?

Pros:

Huge mid/late game
Amazing wave clear
Good lockdown potential
Dope voice lines
Unique ADC play style.

Cons:

Very squishy
Low mobility*
Weak early game
Easy to get behind with, hard to catch up.

*Xayah's W gives increased movement speed if it hits an enemy champion. This gives more mobility for a brief period of time, but requires moving into potential danger areas.
