Xayah is a very good champion to play if you are looking for a fun adc that is not too hard to start off with, but is very hard to master. Both late and early game, Xayah can deal massive damage if her abilities are used correctly. Her passive makes it so after using an ability, you get charges o more powerful feathers from autos that pierce through enemies, and leave feathers on the ground. After using her Q or W, try to get off at least one auto attack because this will make it possible to recall her feathers, and root the enemy. Always keep in mind that 3 feathers being recalled need to hit the enemy to root them, so always try to get as many down as you can for a higher chance of rooting and more damage. Xayah's E is her most powerful ability because it can be used after any ability to deal extra damage and root. Xayah's R is not very strong by itself, but when also used with her E can deal massive damage to many enemies. Always make sure your E is ready before using your R. Her Q is very useful for chip damage and then rooting. Her W is mainly for when she is in a full on fight with an enemy, and need to do as much damage as possible. If you are looking for a strong and fun ADC, I would recommend picking up Xayah.
