I main Xayah and in here it shows Press The Attack is the keystones you should use. Xayah has the 2nd weakest early game out of any champ. When I use Press as my keystones I start or with 72 AD at lvl1. I've used Kelptomancy on her for the past few days and I start out with 88 AD at lvl1. Since she relies on her auto attacks to get her feathers out (after her Q and W have been activated) I've found it really helpful just because her early game is so bad.
Well they are some few changes i want to make to the runes but even these are not bad combined...well done
