Hi, I'm Haytham, although I joined this community for a year, I want to create my own guides, and I have read many guides from previous creators in Mobafire, Mobalytics as the references
If you have any questions or suggestions about the guide then feel free to leave a comment, I try to respond to everything. If you want to support me, an upvote or +rep would be very appreciated.

I. Abilities

Passive - Clean Cuts: After casting an ability, Xayah's next 3 basic attacks penetrate through all enemies. At the end of their path, a Feather will be left in the ground for 6 seconds. This is the bread and butter of Xayah's Kit. Get used to maximizing the amount of feathers on the ground.

Q - Double Daggers: Xayah throws two feather-blades in quick succession, dealing Attack damage physical damage to all enemies hit and leaving two Feathers on the ground. This is your source of poke in lane phase and damaging champs that out range you, it also allows you to use your passive.

W - Deadly Plumage: Xayah creates a storm of blades for 4 seconds that grants her Attack speed icon bonus attack speed and cause her basic attacks to strike an additional time for 20% damage. If you have a Rakan he will also gain this attack speed buff and gain movement speed off you autoing enemy champs! Using this ability plus lethal tempo rune turns you into a turret and allows you to get a load of feathers out.

E - Bladecaller: Xayah calls all Feathers back to her, dealing physical damage to enemies they pass through, the more feathers, the more damage! This is what seperates the good from the great. Knowing when to call this back is the most important part of Xayah and is why i love this champ so much, you can win teamfights solo with a good E!

R - Featherstorm: Xayah leaps into the air, becoming Playful untargetable for 1.5 seconds, during which she is still able to move, then rains down daggers which deal physical damage and leave behind a line of 5 Feathers. Using ult to dodge extreme CC or a assassins combo is really important! Its also really useful to use Xayah's ult to juggle tower aggro in a dive!

II. Pros and Cons

Pros:
- Can solo carry
- Can escape most assassins
- Insane wave clear
- Lots of damage!
- Self Peel and good CC

Cons:
- Immobile
- Ult cooldown is very long
- Bad at chasing
- Low range
- Needs certain supports or isnt as impactful!

In starting game, try rushing to level 3,
Try to force your opponent by spreading the feathers in order not to let them farming and keep them at bay
W is essential in duel and turret pushing
After having the R, use in some case to escape or shut down the opponent

I have included my builds including runes and items above, you can try one of them if you like.
And there will be updated depends on new seasons, this build is not permanent
